Value Collection R82222920 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R82222920 is a hex head cap screw sized 5/8-11 x 2-3/4 inches, manufactured from 18-8 stainless steel with no surface coating applied. The 5/8-11 designation indicates a 5/8-inch nominal diameter with 11 threads per inch on a Unified National Coarse (UNC) thread form. At 2-3/4 inches of length under the head, this fastener provides substantial grip length for structural and mechanical assemblies. It meets the MS 35307-467D military standard, making it appropriate for applications where dimensional and material traceability is required. Installation is performed with standard hex drive tooling. Tradespeople across HVAC, plumbing, electrical, and general mechanical work use cap screws of this type when corrosion resistance and thread integrity are priorities.

This cap screw is suited for indoor and outdoor installations where exposure to moisture, mild chemicals, or corrosive environments makes carbon steel fasteners unsuitable. Common applications include equipment mounting, panel assembly, pipe hanger installation, and structural connections in mechanical rooms, rooftop units, and utility spaces. The 18-8 stainless steel composition resists rust and oxidation without requiring a protective coating, which simplifies maintenance and inspection over the service life of the assembly.

Key Features

• 5/8-11 UNC thread form for broad compatibility with standard tapped holes and hex nuts
• 2-3/4 inch length under head suits medium-depth fastening applications
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Uncoated finish allows direct visual inspection of the base material
• Meets MS 35307-467D military standard for dimensional and material compliance

Compatibility

Designed as a direct-fit fastener for any application requiring a 5/8-11 UNC hex head cap screw in 18-8 stainless steel, including assemblies specifying compliance with MS 35307-467D.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using the appropriate hex wrench or socket driver sized for a 5/8-inch hex head cap screw. Verify that the mating tapped hole or nut is also 5/8-11 UNC thread form before installation to avoid cross-threading. De-energize or isolate any equipment before fastener work in live electrical or pressurized mechanical systems. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation measures.
