Value Collection 63528 5/16-18 Unc Hex Socket Cap Screw SS316

Product Description

The VALUE COLLECTION 63528 is a hex socket cap screw designed for secure fastening in applications where a low-profile, recessed-drive fastener is required. Threaded at 5/16-18 UNC, this screw features a 1/4-inch hex drive and measures 1 inch in length under the head. It is manufactured from 316 stainless steel, offering strong corrosion resistance in wet, marine, and chemically aggressive environments. This type of fastener is installed by maintenance mechanics, pipefitters, plumbers, and HVAC technicians wherever reliable clamping force and resistance to oxidation are priorities.

This screw is suited for use in residential and commercial mechanical systems, structural assemblies, and equipment enclosures where UNC thread engagement and corrosion-resistant materials are specified. The 5/16-18 UNC thread is a standard unified coarse thread, compatible with common tapped holes and threaded inserts in that size. Minimum order quantity is 25 pieces per order, and each package contains 1 piece.

Key Features

• 316 stainless steel construction provides enhanced resistance to corrosion, pitting, and chloride exposure
• 5/16-18 UNC thread for reliable engagement with standard unified coarse tapped holes
• 1/4-inch hex drive socket for use with standard hex keys or socket drivers
• 1-inch length under head suits moderate-depth clamping applications
• Low-profile socket cap head allows use in recessed or space-constrained installations

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring that thread size and a 1/4-inch hex drive, including mechanical equipment, enclosures, and piping system components.

Installation Notes

Install using a properly sized 1/4-inch hex key or socket driver to avoid stripping the drive. Power down or de-energize any equipment before accessing fastener locations inside electrical or mechanical enclosures. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly. Inspect threads and mating hole for contamination or damage before installation.
