Professional Applications & Engineering Value
This 316 stainless steel flanged button head screw delivers exceptional value in corrosive and demanding industrial environments. The combination of M8 x 1.25mm coarse threads with Class 6g tolerance provides reliable fastening in machinery, marine equipment, and chemical processing applications where vibration resistance and easy assembly are critical. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making it ideal for outdoor, marine, and chemical exposure scenarios. The integrated flange design distributes clamping force effectively, preventing surface damage while the button head profile offers a low-profile, aesthetically pleasing finish. These metric fasteners are engineered to maintain integrity in temperature variations and aggressive atmospheres, reducing maintenance frequency and replacement costs.
Specification Summary & Compliance
This fully threaded screw features M8 x 1.25mm coarse threads with Class 6g thread fit per ISO metric standards. The 12mm length and 17.8mm flange diameter provide precise dimensional control. Manufactured to ISO 7380 specifications, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while maintaining consistent quality and performance standards.
