Value Collection 581477PS Hex Socket Cap Screw 3/8-16

Product Description

The Value Collection 581477PS is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and trade applications. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean, low-reflectance appearance suited to demanding environments. The screw features a 3/8-16 UNC thread and a 5/16-inch hex drive socket for use with a standard hex key or Allen wrench. With a 5.5-inch length under head and partial threading, it is well-suited for through-bolt applications where thread engagement is needed only at the mating end. Installation is straightforward for any mechanic, millwright, or maintenance technician working with threaded fasteners.

This cap screw is appropriate for general mechanical assembly, equipment mounting, fixture fabrication, and structural fastening in both residential and commercial settings. Partial threading allows the unthreaded shank to act as a precise locating feature in close-tolerance assemblies. The black oxide alloy steel construction makes it a reliable choice in shop environments where standard zinc-plated fasteners are inadequate for load requirements. This item is sold individually but must be ordered in multiples of 5.

Installation Notes

Install using a 5/16-inch hex key or T-handle Allen wrench. Ensure the mating tapped hole is clean and free of debris before threading. Power down and de-energize any equipment before accessing fastener locations on live machinery. Follow applicable machine-specific service documentation for proper seating procedure and inspection requirements.
