Socket Head Button (Dome) Screw UNC 1/4 x 5/16 inch in A2 Stainless - ASME B18.3

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.
