6C37KFC, 6-32X 3/8 In. Flat Head Socket Cap Screw, Alloy Steel, Thermal Black Finish

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. These socket head cap screws feature a hexagonal center recess in the head for tightening with an Allen wrench or hex key. With no side clearance restrictions, they can be placed close together and are ideal for assemblies with close tolerances. Flat head socket screws feature an 82° countersunk flat head. Flush mounts so moving parts can pass over freely. Not ideal for applications that require optimal anti fatigue properties.
