Professional Applications & Engineering Value
This M8 flat head screw is engineered to address critical sealing challenges in industrial applications where fluid or gas containment is essential. Made from 18-8 stainless steel with a passivated finish, it resists corrosion and maintains integrity in moist or chemical-exposed settings. The silicone rubber O-ring provides a reliable seal against high pressure (up to 6000 psi) and extreme temperatures (-80° to 400° F), making it ideal for machinery, automotive, and HVAC systems. The metric coarse thread with Class 6g fit ensures quick, secure fastening, while the undercut flat head design allows for a smooth surface finish, reducing the risk of snagging and improving safety in dynamic environments.
Specification Summary & Compliance
This screw features a M8 x 1.25mm thread with Class 6g tolerance and coarse spacing, ensuring dimensional accuracy per metric standards. It is manufactured in compliance with DIN 965 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and safe industrial use.
