Value Collection V70210PS Hex Jam Nut 7/8-9 316 Ss

Product Description

The VALUE COLLECTION V70210PS is a 7/8-9 UNC hex jam nut machined from Grade 316 stainless steel with a bright, uncoated finish. Jam nuts are thinner than standard hex nuts and are used primarily as locknuts to secure a mating nut or threaded fastener in position. The 316 stainless alloy provides strong resistance to corrosion in wet, chemical, and marine environments. This nut features right-hand thread and measures 1-5/16 inches across the flats with a height of approximately 31/64 inches. It is sold individually and suited for general industrial, mechanical, and trade assembly applications.

This jam nut is appropriate for use in plumbing, HVAC, pool equipment, and general mechanical assemblies where a corrosion-resistant locknut is required. The 7/8-9 UNC thread size fits standard fractional fastener systems. Its compact jam-nut profile makes it well suited for applications with limited vertical clearance on the threaded shaft, including pump mounts, bracket assemblies, and equipment tie-downs in corrosive or wet service environments.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Jam nut profile allows use as a locknut against a standard hex nut or shoulder
• Right-hand 7/8-9 UNC thread standard for compatibility with standard fractional fastener systems
• Bright uncoated finish preserves dimensional accuracy and allows visual inspection of the base material
• 1-5/16 inch across-flats dimension fits standard 1-5/16 inch wrenching tools

Compatibility

Designed for use with 7/8-9 UNC right-hand threaded fasteners in standard fractional fastener assemblies. Suitable for general industrial and trade applications requiring a Grade 316 stainless steel jam nut.

Installation Notes

Installation is performed by hand-threading the jam nut onto the fastener and then tightening with a standard 1-5/16 inch open-end or combination wrench. When used as a locknut, thread the jam nut first, then the primary nut, and tighten the two against each other. Ensure threads are clean and free of debris before assembly. No special tools or trade license is required for fastener installation, though the surrounding system should be de-energized or depressurized before any fastener work is performed on live equipment.
