Value Collection R82222400 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R82222400 is a 1/4-28 hex head cap screw with a 1-1/2 inch length under head, manufactured from 18-8 stainless steel with an uncoated finish. The 1/4-28 designation indicates a 1/4 inch nominal diameter with 28 threads per inch, conforming to the Unified National Fine (UNF) thread standard. This fastener is suited for applications where corrosion resistance is required without the need for an additional protective coating. Tradespeople, maintenance technicians, and assembly professionals working in corrosive or wet environments rely on 18-8 stainless construction for long-term joint integrity.

This screw is appropriate for general mechanical assembly, equipment maintenance, and structural fastening tasks in residential and commercial settings. The UNF thread form is commonly found in precision equipment, HVAC components, plumbing fixtures, and electrical enclosures where fine-thread engagement provides greater holding strength in thinner materials. It is sold individually with a minimum order quantity of 10 units, making it practical for both service calls requiring a handful of fasteners and larger installation jobs.

Key Features

• 1/4-28 UNF thread for fine-pitch engagement and higher clamping force in thin or precision materials
• 1-1/2 inch length under head for standard through-bolt and tapped-hole applications
• 18-8 stainless steel construction provides corrosion resistance in wet and mildly chemical environments
• Uncoated finish maintains dimensional accuracy and avoids coating-related tolerance interference
• Meets MS 35308-312D military standard specification
• Inch measurement system with length measured from under the head

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw for use in any application specifying that thread size, length, and 18-8 stainless steel material. Conforms to MS 35308-312D standard.

Installation Notes

Install using an appropriately sized hex wrench or socket driver rated for the fastener diameter. Power down or de-energize any equipment before accessing fastener locations inside electrical or mechanical enclosures. Avoid over-torquing stainless steel fasteners, as galling can occur; apply a compatible anti-seize compound when fastening stainless to stainless. Follow applicable equipment manufacturer specifications and relevant codes for the trade and installation type.
