• Full-thread engagement along the 30 mm length, offering maximum grip and pull-out resistance in various material thicknesses
• Regulatory compliance with RoHS 3 and REACH standards, ensuring safety and environmental responsibility in global supply chains

Professional Applications & Engineering Value

Engineered for demanding settings, these M8 flat head screws in 316 Stainless Steel address critical challenges like corrosion in marine, chemical, or outdoor installations. The passivated finish enhances surface durability, while the Class 6g thread and coarse pitch ensure quick, reliable assembly with standard metric tools. The undercut flat head and 100° countersink angle minimize protrusion, making them ideal for machinery, enclosures, and structural components where a smooth surface is essential. With full threading and high tensile strength, they provide robust, long-term fastening solutions that withstand vibration and dynamic loads, reducing maintenance needs and downtime in industrial operations.

Specification Summary & Compliance

This screw meets precise dimensional standards, including a Class 6g thread fit per metric specifications, head diameter tolerance of -0.127 to 0.127 mm, and M8x1.25 mm coarse threading. Manufacturing adheres to industry norms for flat head screws, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The combination of 316 Stainless Steel material and controlled hardness supports consistent performance in technical applications.
