HT Socket Button Head Cap Allen Bolt M4 X 8mm-25 Pcs

Hex drive Socket Cap Screws are often found in applications where there is insufficient wrench/socket clearance for hex head cap screws, or when a “finished” look is desired. Button heads provide a larger bearing surface and a lower head profile than Socket heads and are used when the material is too thin to countersink. Because of their smaller outer diameter, Socket Head screws may be preferred and are sometimes recessed (counterbored). When clearance is an issue, use a Low Socket Head instead of a Socket Head.

EasyMech HT Socket Button Head Cap Allen Bolt are recommended for high strength applications. Button and Flatheads are suggested when only moderate strength is needed. For Button and Socket heads, measure the length from under the head. For Flat heads, length includes head height

A socket cap bolts, also known as a socket head capscrew, socket screw, or Allen bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole. The term socket head capscrew typically refers to a type of threaded fastener whose head diameter is nominally 1.5 times that of the screw shank (major) diameter, Forged heat-treated alloy examples are high strength fasteners intended for the most demanding mechanical applications, with special alloy formulations available that are capable of maintaining strength at temperatures in excess of 1000 degrees F (587ºC).
