  In the vast landscape of manufacturing and engineering, standard fasteners like screws, bolts, and nuts play a crucial role. However, when off-the-shelf solutions don't quite fit the bill, custom fasteners step in to bridge the gap. These specialized components are designed and manufactured to meet the unique and specific requirements of a particular application. Why opt for custom fasteners? The reasons are varied and often critical. In some cases, standard fasteners may not offer the necessary material properties to withstand extreme temperatures, corrosive environments, or high levels of stress. Customization allows engineers to select specific alloys, coatings, and heat treatments to ensure optimal performance and longevity. Furthermore, the geometry of an application might demand a non-standard head shape, thread type, or overall dimension. Custom fasteners can be engineered with precise dimensions and features to ensure a perfect fit and seamless integration within the assembly. This is particularly important in industries like aerospace, medical devices, and automotive, where precision and reliability are paramount.   The process of creating custom fasteners typically involves close collaboration between the client and the manufacturer. Engineers discuss the specific needs, including load requirements, environmental conditions, and integration constraints. Using advanced design software and manufacturing techniques, prototypes are often created and tested rigorously before mass production.   While custom fasteners may come with a higher initial cost compared to standard options, the long-term benefits often outweigh this investment. Improved performance, enhanced safety, and increased lifespan of the final product are just some of the advantages. In essence, custom fasteners empower engineers and manufacturers to overcome limitations and achieve optimal results in even the most demanding applications, proving that sometimes, a tailored solution is the only solution.

Stainless steel screws are threaded components used to connect or secure two or more objects. They are made of stainless steel and typically have high strength, corrosion resistance, rust resistance, and long lifespan. The toughness of stainless steel screws is their ability to withstand impact and vibration. Different materials can affect their toughness. Stainless steel screws The main characteristic of stainless steel screws is their corrosion resistance, and the corrosion resistance of stainless steel screws of different materials varies in different environments Stainless steel screws come in various types and specifications, including different head shapes (such as round head, half round head, flat head, cylindrical head, etc.) and different thread types. Stainless steel screws are widely used in fields such as architecture, machinery, electronics, automobiles, aerospace, and are commonly used to connect and fix steel plates, wood, plastics, and other materials. They are usually tightened and connected through the mutual fit of threads and nuts. In many applications, stainless steel screws are a very suitable choice, especially when corrosion resistance is required. However, the suitability of various accessories depends on the specific situation. In some cases, screws made of other materials, such as galvanized steel screws or copper screws, may be more suitable than stainless steel screws. For example, if aluminum alloy accessories are to be connected, the potential difference between stainless steel screws and aluminum alloy is large, which is prone to corrosion. At this time, galvanized steel screws may be more suitable. Therefore, when selecting screw materials, multiple factors such as the material of the accessories used, the usage environment, and the stress situation should be considered, and the selection should be based on the specific situation.

   Over time, the fasteners of precision screws may experience slipping teeth. Even if we twist them with a wrench, we cannot open them. The main purpose of precision screws is to form a fixed body for industrial products. When using teeth and teeth, it is common for screw heads to break, lock too tightly, or the teeth to not lock tightly, which cannot meet the application conditions. Precision screw 1. The screw length is not good and cannot accept the corresponding torque. 2. The strength and hardness of the screw are not good (possibly due to quality reasons such as data (material) and process), and the corresponding torque cannot be accepted. 3. The strength of the screw exceeds the standard load of the screw, resulting in slipping. 4. Screws with threaded holes or threads are non-standard and not strictly compatible with each other. The main purpose of customized screws is to form a fixed body for industrial products. When using teeth and teeth, it is common for screw heads to break, lock too tightly, or the teeth to not lock tightly, which cannot meet the application conditions. All of these are precise quality issues. 5. The screws themselves are irregular and can also result in sliding teeth. 6. The outer diameter of the teeth is small. If a normal machine uses regular threads, the small outer diameter of the teeth will definitely cause the teeth to slip. The main purpose is to form a fixed body for industrial products. When using teeth and teeth, the screw heads often do not close together, cannot be locked with too much force, or the dentin cannot be locked well, thus failing to meet the application conditions. All of these are precise quality issues.

      Screws constitute a fundamental part of any DIY or construction project, but there are a wide variety of types you need to be aware of in order to choose the right one. Depending on their size, thread, head or tip, different types of screw are effective for different purposes. Types of screw according to their drive or head shape When it comes to classifying the different types of screws available, we can start with a fundamental part of this element: the head and its drive. Together, they determine the strength and torque of the screw. ● Phillips screws. This type of screw is one of the most used and has slots in the head in the shape of a cross. The heads are designed to avoid the screwdriver slipping, thus facilitating use. It doesn't usually require a lot of torque when installing and is very useful, for example, for work with wood/ Plastic /Electronics.     ● Torx® screws. Torx® screws have grooves in the shape of a star with six points and are very resistant. The tamper-resistant Torx® screw, especially designed to be extra secure, falls within this classification. It is characterised by its protruding pin in the middle of the six-point star that requires a special tool to turn.     ● Slotted-head screws. Slotted-head screws have a slot in a vertical line and are perfect for joining together two pieces of wood. It is one of the most commonly-used types of screw and is recommended for medium torque jobs.     ● Socket screws. These screws have a cylindrical head with a hexagonal hole in the middle. To work with them, you need an allen key, a tool capable of exerting greater torque than a conventional screwdriver.     ● Pozidriv screws. Pozidriv screws are similar to Phillips screws but have greater torque as they have eight points of contact in the slots, which guarantees good fixing to the surface. They are ideal with work with materials that require a strong hold.     ● Hexagonal head screws. These screws have a hexagonal head. Unlike the other screws, hexagonal head screws do not have any slots and are perfect for fastening metal parts together with the right tool. Also, screws with a hexagonal head that include a flange don't need to have a washer incorporated.     How are screws classified by use? In addition to the different screw heads there are on the market, it is also fundamental to know about the different uses each one has according to the material you will be working with or the particular features that apply. Some of the most common types of screw are detailed below. ● Wood screws. This classification includes various types, but coach screws are the most common. The distance between the thread lines is greater than with conventional screws, which facilitates a much stronger joint thanks to the fact that the screw fastens to the wood more securely. Bear in mind that, if they are going to be visible, there are different types of covering to make the installation more aesthetically-pleasing.     ● Self-drilling screws. Self-drilling screws are those that, as their name suggests, don't need prior drilling to install them as their tip acts as a drill. Within this classification you'll find screws for roofs and façades which are principally hex head self-drilling and favour the joining of metal elements. They have a washer or flange incorporated with EPDM rubber that seals the material you are working on.     ● Screws for laminated plasterboard. Most of these screws have a trumpet head, which allows easy insertion of the screw into the material and provides a gentle but strong torque. Depending on the thickness of the material to be drilled, the tip of the screws for plasterboard may be sharp, perforating or self-drilling. Additionally, the thread tends to be wide in most cases. This guarantees the perfect, long-lasting fastening of laminated plasterboard panels to each other or to wood.     ● Sheet metal screws. In this group of screws you'll find a large variety of types of screw, diameters and lengths depending on the flexibility of the material to be perforated. They are designed to fasten metal elements to each other or to other materials. In this case, they require prior drilling to guarantee the fixing. They have a fine thread which means they can be used at the edges of the material to be fixed.   ● Standardised screws. This classification includes all screws with a metric thread, which are those where the thread follows standard measurements used internationally. There is a large variety of types of head and they can be half thread with a neck or full thread covering the whole body. Another main characteristic is that metric threaded screws have no tip. They are mainly used in machinery with nuts or washers to achieve better fixing of the elements.   Types of screw according to the material Another thing to bear in mind when choosing a screw for any project is the material it is made of. Taking this classification into account, different screws are suitable for different surfaces. The most common are steel screws with a bichromatic or zinc-coated finish, recommended for interiors as they have an average level of corrosion resistance. If work is to take place outdoors, stainless steel screws (A2 and A4) are the best option as they are highly corrosion-resistant in outdoor environments and/or in coastal areas. Additionally, as we have indicated before, bichromatic screws are suitable for projects with wood if they are going to be visible as they make the project more aesthetically-pleasing.   In short, the choice of the different types of screw will depend on the characteristics of each application. It is important to be aware of their differences to find the one that will perform best in each case. At LOCK we specialise in fixings that suit your needs and have a wide range of screws for all types of application.

Screw dispensing is a special fastener processing technology that sprays traditional adhesive onto screw threads through automated equipment, typically at 180 ° and 360 °. It is commonly used in mobile precision electronic products, such as laptops, mobile phones, etc. Its main advantages include: 1. Compared to non glued screws, it has better anti loosening function and can withstand long-term continuous vibration without loosening the screws. 2. Better installation, replacing traditional production line on-site dispensing. The installation personnel have different methods, resulting in uncertainty in the amount of glue, while also not damaging the surface of fasteners and connectors. Rework and disassembly are also easy. 3. Widely applicable, it can be applied in automated assembly, resulting in higher production and installation efficiency.
