Value Collection R63084688 Hex Jam Nut 3/4-10 18-8 Ss

Product Description

The VALUE COLLECTION R63084688 is a 3/4-10 UNC hex jam nut manufactured from 18-8 stainless steel with an uncoated finish. Jam nuts are thin hex nuts used primarily as locknuts — threaded against a standard nut or against a component to resist loosening under vibration and torque. At 27/64 inches in height and 1-1/8 inches across the flats, this nut follows standard dimensional tolerances for 3/4-10 unified coarse thread fasteners. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, chemical-exposure, and outdoor environments. Plumbers, HVAC technicians, electricians, and mechanical contractors install jam nuts in pipe supports, equipment mounting assemblies, and threaded rod applications.

This jam nut is suited for residential and commercial trade applications where a thin locking nut is required on 3/4-10 UNC threaded rod, bolts, or studs. Common uses include pipe hanger assemblies, equipment vibration isolation mounts, conduit support hardware, and general mechanical fastening where corrosion resistance is a priority. The right-hand thread direction is standard for the vast majority of threaded fastener assemblies encountered in trade work.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• 3/4-10 UNC right-hand thread fits standard unified coarse thread rods and bolts
• Jam nut profile at 27/64 inches height functions as a locknut against a mating nut or component
• 1-1/8 inches across flats accepts standard 1-1/8 inch hex wrenches and sockets
• Uncoated finish — no plating that can flake or interfere with stainless-on-stainless galling considerations

Compatibility

Designed for use with 3/4-10 UNC threaded rod, bolts, and studs in standard unified coarse thread assemblies. Suitable wherever an 18-8 stainless steel jam nut is specified for that thread size.

Installation Notes

Install using a standard 1-1/8 inch open-end wrench, combination wrench, or socket. When using stainless steel fasteners, apply an anti-galling compound or zinc-based anti-seize to the threads before assembly, as stainless fasteners are prone to galling under high torque. Power down or de-energize any equipment before working on mounting or support assemblies. Follow applicable mechanical and structural codes for the specific installation type.
