Value Collection 211271PR Flat Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION 211271PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 1/4-inch hex socket, making it compatible with standard Allen wrenches and hex keys. The screw is sized at 7/16-14 UNC thread with an overall length of 1.75 inches and is fully threaded along that length. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance for interior and protected exterior use. Machinists, millwrights, and maintenance technicians commonly install this fastener in machine frames, fixtures, and assemblies where a low-profile head is required.

This flat socket cap screw is suited for use in mechanical assemblies, tooling fixtures, machine guards, and structural fabrications where the head must sit flush with or below the mating surface. The 7/16-14 UNC thread size is a common inch-series coarse thread used across a wide range of industrial and OEM equipment. The black oxide finish provides a clean appearance and mild protection in dry or lightly oiled environments. Maintenance professionals and fabricators working to ASME/ANSI B18.3 or ASTM F835 standards will find this fastener meets those specifications directly.

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 7/16-14 UNC countersunk fastener per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/4-inch hex key or Allen driver. A properly sized 82-degree countersink must be prepared in the mating material before installation to allow the head to seat flush. De-energize, de-pressurize, or otherwise make safe any equipment before fastener service. Do not exceed the rated mechanical limits of the fastener by applying impact tools without appropriate torque control.
