Value Collection R82222448 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R82222448 is a 1/4-28 hex head cap screw measuring 1-1/4 inches under the head, manufactured from 18-8 stainless steel with no additional coating. The fine-thread UNF profile provides strong thread engagement in ferrous and non-ferrous base materials where vibration resistance and corrosion resistance are both required. The 18-8 stainless alloy offers reliable performance in wet, marine, and chemically exposed environments without the galvanic concerns associated with carbon steel fasteners. This screw is suitable for mechanical assemblies, equipment frames, and structural connections across a range of trade applications where a hex drive and fine-pitch thread are specified.

This fastener is used in light industrial, HVAC, plumbing, and electrical panel assembly work wherever a 1/4-28 fine-thread hex cap screw is called out. The uncoated 18-8 stainless finish makes it appropriate for indoor and outdoor installations where corrosion resistance matters but a plated or coated finish is not specified. It meets multiple military standard specifications, making it a fit for aerospace-adjacent, defense, and OEM service applications. Minimum order quantity is 10 pieces; individual package quantity is 1.

Key Features

Suitable as a direct replacement wherever a 1/4-28 x 1-1/4 inch 18-8 stainless hex cap screw is specified.

Installation Notes

Installation is performed by a mechanic, technician, or tradesperson using a standard hex wrench, socket, or open-end wrench sized for a 1/4-28 fastener. Always verify thread engagement depth in the mating component before torquing; fine-thread fasteners require clean, undamaged threads to seat properly. Inspect the receiving hole for debris or thread damage prior to installation. Follow the torque specifications provided by the equipment manufacturer or applicable industry standard for the assembly being serviced.
