The VALUE COLLECTION R82222913 is a 5/8-11 hex head cap screw manufactured from 18-8 stainless steel with an uncoated finish. It measures 2-1/2 inches under the head and uses a Unified National Coarse (UNC) thread form. The 18-8 stainless steel construction provides solid corrosion resistance in wet, chemical-exposure, and marine environments where carbon steel fasteners would degrade. Licensed trades — including plumbers, HVAC mechanics, electricians, and general contractors — use this fastener when code or application conditions call for stainless-grade hardware. The inch-system thread designation makes it a direct fit for standard UNC tapped holes and hardware.
This screw is suited for structural and mechanical assemblies where corrosion resistance is required. Common applications include equipment mounting, pipe hangers, utility panel hardware, pump and compressor installations, and general trade work in coastal, industrial, or high-humidity environments. The UNC 5/8-11 thread size is a widely used coarse pitch in both commercial and residential mechanical installations. Fastener is sold individually.
Conforms to MS 34307-341D, MS 35307-303D, MS 35307-305D, MS 35307-306D, MS 35307-307D, MS 35307-308D, MS 35307-310D, MS 35307-312D, MS 35307-313D, MS 35307-314D, MS 35307-316D, MS 35307-318D, MS 35307-331D, MS 35307-334D, MS 35307-336D, MS 35307-338D, MS 35307-340D. Designed as a direct-replacement fastener for any 5/8-11 UNC hex head cap screw application calling for 18-8 stainless steel material grade.
Installation should be performed by a qualified trades professional familiar with fastener torque requirements for the application and material being joined. Always power down or de-energize equipment before replacing fasteners on electrical or mechanical assemblies. Use the appropriate hex wrench or socket for a 5/8-inch hex head drive to avoid fastener damage. Verify thread engagement depth meets the requirements of the joint design before final tightening.
