A black 3/8″ – 16 allen head socket cap screw head, made of steel.
- Allen head socket cap screws feature a hexagonal recess in the head for tightening with hex keys or Allen wrenches.
- No side clearance restrictions mean that they are ideal for applications and assemblies with close tolerances.
- Since they are internally wrenched, Allen head socket cap screws need less counter-bore.
They also usually have higher tensile strength, greater shear strength, and better yield strength than comparable sizes of standard hex head cap screws. - Made of heat-treated alloy steel
- Finished with thermal or chemical black oxide
