1/4 inch UNC Socket Head Button Screws ASME B18.3-2012 in Mechanically Plated Zinc Steel

A popular and attractive socket head screw, typically used where aesthetics are important, or where a lower profile domed finish is required. The hex drive is generally smaller than other hex driven ranges and thus the ultimate tightening torque is reduced. Manufactured to ASME/ANSI B18.3, and always fully threaded.
