Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 316 stainless steel flat head screws address critical challenges like corrosion, vibration loosening, and mechanical stress. The passivated finish enhances surface integrity, preventing galling and rust in marine, chemical processing, and outdoor applications. With a fully threaded UNC coarse design and Class 2A thread fit, they provide superior pull-out resistance and ease of installation in metals, plastics, and composites. The Phillips drive and flat head profile allow for seamless, flush mounting, reducing protrusion risks in machinery, enclosures, and structural assemblies where space and aesthetics matter. Ideal for OEMs and maintenance teams requiring RoHS and REACH compliant fasteners that endure harsh conditions without compromising performance.
Specification Summary & Compliance
This screw adheres to ASME B18.6.3 specifications, ensuring dimensional accuracy and interchangeability. Threads are UNC 6-32 coarse with a Class 2A fit for consistent tolerance, while the 82° countersink angle supports standard flat head applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance control.
