### 1. **Product Standard and Design** - Conform to DIN912 standard, ensuring high - quality and interchangeability in industrial applications. The hexagon socket cap head design allows for efficient torque transfer using Allen keys, reducing the risk of cam - out during tightening and loosening. ### 2. **Size Range** - Available in metric sizes from M3 to M10, catering to a wide variety of fastening needs in different mechanical and structural assemblies. This size range is commonly used in electronics, machinery, and general equipment manufacturing. ### 3. **Material Composition** - Constructed from high - grade SS 304 and SS 316 stainless steel. SS 304, with its 18 - 20% chromium and 8 - 10.5% nickel content, offers excellent corrosion resistance in most general - purpose environments. SS 316, containing an additional 2 - 3% molybdenum, provides superior resistance to harsh chemicals, saltwater, and higher - temperature conditions, making it suitable for more demanding applications such as marine and chemical industries. ### 4. **Assembly Design** - Pre - assembled with washers, these screws ensure even distribution of clamping force, preventing damage to the mating surfaces. The washer helps to reduce the risk of loosening due to vibration, enhancing the overall stability and reliability of the assembly. ### 5. **Surface Finish** - Feature a plain hex finish, which showcases the natural appearance of the stainless steel. This finish provides a basic level of corrosion protection inherent to the stainless steel material. It can also be further passivated upon request to enhance corrosion resistance, or customized with other coatings like PTFE for reduced friction or black oxide for aesthetic and anti - glare purposes. ### 6. **Applications** - Widely used in industrial machinery for component assembly, where high strength and corrosion resistance are essential. In the electronics industry, they are suitable for securing parts in electronic enclosures due to their non - magnetic properties (especially SS 304). In the food and beverage industry, SS 316 variants are preferred as they meet strict hygiene standards and can withstand cleaning agents and food acids. They are also ideal for marine and outdoor applications due to their excellent corrosion - resistant properties. ### 7. **Quality Assurance** - Undergo strict quality control processes. Tensile strength tests are conducted to ensure they meet or exceed the minimum requirements for SS 304 and SS 316 materials. Threads are carefully inspected using go/no - go gauges to ensure accurate threading, and the dimensions of the head and shank are verified against the DIN912 standard. Certifications such as RoHS compliance (ensuring freedom from hazardous substances) and material test reports (MTRs) can be provided upon request. ### 8. **Packaging and Supply** - Typically packaged in quantities suitable for industrial use, such as boxes of 500 or 1000 pieces. Moisture - resistant packaging is used to protect the stainless steel from rust during storage and transportation. Available for both small - scale orders and large - volume wholesale purchases, with customized packaging options and timely delivery to meet different customer needs.
