Professional Applications & Engineering Value

This 316 stainless steel rounded head screw delivers critical reliability in corrosive or high-moisture settings where fastener failure is not an option. The fully threaded UNC design with Class 3A precision ensures tight tolerances and vibration resistance in machinery, marine equipment, and chemical processing systems. Its passivated finish enhances the natural corrosion resistance of 316 stainless, while the rounded button head and hex drive provide secure, flush installation without snagging. Engineered to withstand 70,000 psi tensile loads, this screw maintains integrity under stress, reducing maintenance needs and downtime in industrial fastening applications.

Specification Summary & Compliance

This fastener features a 10-24 UNC coarse thread with Class 3A fit for precise engagement, manufactured to ASME B18.3 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. The screw is right-hand threaded and fully threaded along its 2" length, with a hardness of Rockwell B55 and a passivated surface treatment for enhanced durability.
