Value Collection R82222882 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R82222882 is a 5/8-11 hex head cap screw measuring 1-1/2 inches under the head, manufactured from 18-8 stainless steel with no additional finish or coating. The 18-8 stainless alloy provides solid corrosion resistance in wet, chemical-exposure, and outdoor environments, making this fastener well suited for plumbing, HVAC, pool equipment, and general mechanical assembly. The Unified National Coarse (UNC) thread form is the standard for most inch-system structural and mechanical connections. Installed with a standard hex wrench or socket, this cap screw is a common choice for trade professionals assembling or servicing equipment where corrosion resistance is a priority.

This fastener is used across residential and light commercial applications wherever a 5/8-11 UNC threaded connection is required. Typical install scenarios include equipment mounting, pipe hanger assemblies, pump bases, and mechanical panel supports. The uncoated 18-8 stainless finish suits installations in humid or corrosive environments such as mechanical rooms, rooftop equipment curbs, and poolside equipment pads. It meets military standard MS 35307-462D, which defines dimensional and material requirements for stainless hex head cap screws in this size range.

Key Features

• 5/8-11 UNC thread for compatibility with standard inch-system tapped holes and hex nuts
• 1-1/2 inches length under head for accurate torque and thread engagement in standard applications
• 18-8 stainless steel construction resists rust and corrosion in wet or outdoor environments
• Uncoated finish eliminates concern over coating delamination or chemical interaction
• Meets MS 35307-462D military standard for dimensional and material conformance

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw for use in any application requiring an inch-system fastener of this thread size and length in 18-8 stainless steel.

Installation Notes

Installation is performed by hand-threading the screw into a pre-tapped or through-bolted hole, then torquing to the value specified by the equipment manufacturer using a standard hex socket or wrench. De-energize and isolate all equipment before working in areas where live electrical or pressurized systems are present. Do not mix stainless fasteners with carbon steel hardware in the same joint without accounting for galvanic compatibility. Follow applicable mechanical and structural codes for the jurisdiction where the fastener is being installed.
