Value Collection R82234911 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R82234911 is a 1/4-20 x 1-1/2 inch hex head cap screw machined from 18-8 stainless steel with no coating applied. The 1/4-20 designation indicates a 1/4-inch nominal diameter with 20 threads per inch on a Unified National Coarse (UNC) thread form. Length under head measures 1-1/2 inches. The 18-8 stainless alloy provides corrosion resistance suitable for general industrial, mechanical, and light structural fastening. Installed with a standard hex wrench or socket drive, this fastener is used by millwrights, pipefitters, HVAC technicians, plumbers, and maintenance mechanics across a wide range of trade applications.

This cap screw suits residential and commercial mechanical installations where corrosion resistance and a standard UNC thread form are required. Typical applications include equipment mounting, panel fastening, pipe support hardware, and general machine assembly. The uncoated 18-8 stainless finish is appropriate for indoor and moderate outdoor environments. This fastener meets multiple military standard specifications, making it suitable for assemblies that reference MS-series fastener requirements. Sold individually; minimum order quantity is 10 pieces.

Installation Notes

Installation requires a hex wrench, socket, or nut driver sized for a 1/4-inch hex head cap screw. Always de-energize and lock out equipment before fastening near electrical or mechanical hazard zones per applicable OSHA lockout-tagout procedures. Do not exceed the torque capacity of the 18-8 stainless alloy, which is lower than carbon or alloy steel grades of equivalent size. Use stainless-compatible anti-seize compound when installing into stainless or aluminum tapped holes to prevent galling.
