Socket Head Cap Screw Technical Information

Socket head cap screws feature a hexagonal center recess in the head for tightening with an Allen wrench or hex key. With no sideclearance restrictions, they can be placed close together and are ideal for assemblies with close tolerances.

Standard socket head cap screws typically supply higher tensile strength, better yield strength, and more shear strength than equivalent sizes of hex head cap screws; yet they require less counter-bore because they are internally wrenched.

TYPES

Standard Head
Features a relatively high cylindrical head with a recessed hexagonal socket. Used where maximum tensile strength is essential.

MATERIALS

Stainless Steel—contains a minimum of 12% chromium for exceptional resistance to extreme environmental conditions. Properties are highly anticorrosive. Not affected by scratching; however, not as strong as common alloy steels. May be mildly magnetic.

Socket head cap screws are commonly used in machine assembly, especially for removable panels and parts. They have a round cap with a hex head and are tightened with a socket wrench drive. Choose the right cap head for your specific application. Longer caps are easier to see when fastened, while button and flat head caps are less apt to snag clothing or linkages. Chrome cap screws have a great appearance. Those with a black oxide or armor coat finish resist corrosion. Stock up on socket head cap screws from Grainger to expedite engine and machine maintenance.
