Value Collection R82230422 5/16-18 X 1-1/4 in Hex Cap Screw

Product Description

The VALUE COLLECTION R82230422 is a hex head cap screw sized 5/16-18 x 1-1/4 inches, manufactured from 18-8 stainless steel with an uncoated finish. The 5/16-18 designation indicates a 5/16-inch nominal diameter with 18 threads per inch on a Unified National Coarse (UNC) thread form. Constructed from 18-8 stainless steel, this fastener provides solid corrosion resistance in moderate-exposure environments, making it a dependable choice for mechanical assemblies, equipment mounting, and general structural applications across multiple trades.

This cap screw suits a wide range of light industrial, commercial, and residential applications where a standard hex-drive fastener is required. It is commonly used in HVAC equipment mounting, plumbing fixture installation, electrical panel and enclosure assembly, and pool equipment hardware. The UNC thread form is the most widely used inch-series thread standard in North American trade work, allowing compatibility with standard hex nuts, lock nuts, and tapped holes of matching specification. Minimum order quantity is 10 units.

Installation Notes

Install using a standard hex wrench or socket of the appropriate drive size for 5/16-inch hex head fasteners. Power down or de-energize any equipment before replacing or installing fasteners on electrical enclosures or energized assemblies. Do not mix stainless steel fasteners with incompatible dissimilar metals in applications where galvanic corrosion is a concern. Follow applicable equipment manufacturer torque guidelines and relevant code requirements for the trade discipline involved.
