Value Collection R82222934 Hex Cap Screw 3/4-10 X 3 in 18-8 Ss

Product Description

The VALUE COLLECTION R82222934 is a 3/4-10 hex head cap screw machined from 18-8 stainless steel and supplied in an uncoated finish. With a 3-inch length under the head and a UNC (Unified National Coarse) thread form, this fastener is built for structural and mechanical assemblies where corrosion resistance is a priority. The 18-8 alloy designation indicates an austenitic stainless grade with approximately 18 percent chromium and 8 percent nickel, delivering solid resistance to rust, oxidation, and mild chemical exposure. Licensed tradespeople and assembly technicians reach for this grade when galvanic compatibility and longevity in wet or outdoor environments matter more than raw tensile strength.

This hex cap screw is appropriate for general mechanical, structural, and trade-service applications including HVAC equipment mounting, plumbing skid assemblies, pool equipment frames, and electrical enclosure hardware. The 3/4-10 UNC thread mates with standard 3/4-10 nuts, inserts, and tapped holes used throughout commercial and residential mechanical systems. The uncoated finish keeps the fastener ready for direct installation without the risk of coating interference in close-tolerance tapped holes.

Key Features

• 3/4-10 UNC thread form compatible with standard 3/4-10 nuts and tapped holes
• 3-inch length measured under the head for consistent stack-up calculations
• 18-8 stainless steel construction resists corrosion and oxidation in wet or outdoor environments
• Uncoated finish maintains thread tolerances and simplifies installation
• Meets MS 35307-491D standard for dimensional and material conformance

Compatibility

Designed as an OEM-style replacement and general-service fastener for any 3/4-10 UNC tapped hole or nut application requiring 18-8 stainless steel material per MS 35307-491D.

Installation Notes

Installation is performed by licensed mechanical, plumbing, HVAC, or electrical tradespeople using a standard 1-1/8-inch hex wrench or socket. Always verify thread engagement depth and mating material compatibility before installation, particularly when threading into aluminum or mild steel to avoid galvanic corrosion. Clean tapped holes of debris before driving the fastener. Do not use impact tools at full torque without a torque-limiting socket, and always confirm final torque values against the equipment manufacturer's specifications.
