Value Collection R82222462 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R82222462 is a 1/4-28 UNF hex head cap screw manufactured from 18-8 stainless steel with an uncoated finish. Sized at 1/4-28 thread and 2 inches under the head, this fastener delivers corrosion resistance appropriate for wet, marine, and chemical-exposure environments. The fine thread UNF profile provides stronger clamping force and better resistance to loosening under vibration compared to coarse-thread variants. Licensed tradespeople and maintenance technicians working on HVAC equipment, plumbing assemblies, and electrical enclosures rely on this grade for applications where galvanic compatibility and corrosion performance are required. This screw meets MS 35308-314D standards, confirming dimensional and material compliance for applications where documentation is necessary.

This fastener is suited for light industrial, commercial, and residential mechanical assemblies requiring a fine-thread stainless fastener. Typical use cases include panel mounting, equipment framing, conduit support hardware, and plumbing fixture installation where exposure to moisture or mild chemicals rules out plain steel or zinc-plated alternatives. The 18-8 stainless composition performs reliably across the temperature ranges common in HVAC and mechanical rooms. No special coatings or thread treatments are applied, so the fastener threads in cleanly with standard tooling.

Key Features

• 1/4-28 UNF fine thread for higher clamping force and vibration resistance
• 2-inch length under head for deeper engagement in thick assemblies
• 18-8 stainless steel construction for corrosion resistance in wet and chemical environments
• Uncoated finish — no risk of coating interference with threaded holes or torque readings
• Meets MS 35308-314D dimensional and material standard
• Inch system of measurement for compatibility with standard SAE tooling

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw for use in any application requiring an inch-series fine-thread stainless fastener in this size and length.

Installation Notes

Install using a standard hex head wrench or socket driver sized for a 1/4-inch hex cap screw. De-energize and lock out any electrical or mechanical equipment before accessing fastener locations inside panels or enclosures. Avoid mixing stainless fasteners with dissimilar metals in direct contact in high-moisture environments to minimize galvanic corrosion risk. Apply anti-seize compound if the fastener will be installed into an aluminum or stainless threaded hole that may be difficult to remove after extended service.
