Professional Applications & Engineering Value

Engineered for demanding applications, these 6-32 UNC flat head screws in 316 Stainless Steel provide exceptional durability where corrosion resistance is critical, such as in marine, chemical processing, and outdoor equipment. The passivated finish enhances surface protection, reducing the risk of thread galling and failure. With a coarse thread spacing and fully threaded body, they offer quick assembly and superior pull-out resistance in soft materials or pre-tapped holes. The hex drive ensures high torque transmission without cam-out, making them ideal for machinery, enclosures, and structural assemblies requiring reliable, long-term performance under stress.

Specification Summary & Compliance

This screw adheres to ASME B18.3 and ASTM F879 specifications, with a Class 3A thread fit for precise tolerances and a 82° countersink angle for standard flush mounting. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and regulatory acceptance in industrial supply chains.
