Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Excellent flush-mounting capability thanks to the standard 90° flat head and countersink angle, providing a smooth, secure finish.
- High mechanical strength and durability from a Rockwell B71 hardness and 60,000 psi tensile strength, ensuring reliable performance under load.
- Efficient and secure fastening with a fully threaded M3 coarse thread and Class 6h fit, offering strong holding power and easy installation.
- Broad tool compatibility and ease of use with the Phillips No. 1 drive, allowing for quick assembly with common tools.
- Guaranteed dimensional precision and interchangeability by conforming to the stringent DIN 965 standard for metric flat head screws.
- Safe for regulated industries as the screw is fully compliant with RoHS 3 and REACH environmental regulations.
Professional Applications & Engineering Value
This M3 flat head screw is engineered from zinc-plated steel to solve common industrial challenges like component loosening and corrosion-induced failure. Its fully threaded coarse metric thread with a 0.5mm pitch ensures maximum grip and vibration resistance in materials such as metal, plastic, and wood. The 90° countersink angle and flat head design allow for a completely flush installation, which is critical in applications where protruding hardware is not an option, such as in machinery panels, automotive assemblies, and electronic enclosures. By meeting DIN 965 specifications, it provides reliable dimensional consistency for industrial manufacturing and maintenance, reducing assembly time and improving the longevity of the final product.
Specification Summary & Compliance
This screw features a M3 x 0.5mm coarse thread with a Class 6h thread fit, ensuring precise dimensional accuracy per ISO metric standards. It is manufactured to conform to the DIN 965 standard for flat head screws. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety requirements for hazardous substances.
