Value Collection 329150PS Hex Jam Nut 9/16-12 Grade 2

Product Description

The VALUE COLLECTION 329150PS is a 9/16-12 UNC hex jam nut machined from Grade 2 steel with a bright, uncoated finish. Jam nuts are low-profile fasteners used primarily as locknuts to secure a standard hex nut in place or to fasten components where thread engagement depth is limited. This nut features right-hand threading and measures 7/8 inches across the flats with a height of 5/16 inches. At 0.01 pounds, it is a lightweight hardware component suited for general mechanical and structural fastening applications. Installation is performed by hand tools or wrenches by maintenance technicians, millwrights, or general contractors.

This jam nut is appropriate for general-purpose fastening in residential, commercial, and light industrial settings. It follows the UNC (Unified National Coarse) thread standard, making it compatible with standard 9/16-12 threaded rod, bolts, and fastener assemblies. Typical use cases include machinery assembly, pipe hanger hardware, equipment mounting, and locknut applications where a thin profile nut is required to back up a primary nut.

Key Features

• 9/16-12 UNC right-hand thread for compatibility with standard coarse-thread fastener systems
• Grade 2 steel construction for general-purpose mechanical strength
• Bright uncoated finish suitable for dry or protected indoor environments
• Low-profile jam nut design at 5/16 inches height for space-limited applications
• 7/8 inches across flats for standard wrench fit

Compatibility

Designed as a general-purpose replacement or supplemental jam nut for 9/16-12 UNC threaded fastener assemblies in mechanical, structural, and maintenance applications.

Installation Notes

A licensed or qualified technician should verify thread compatibility before installation. Power down or de-energize any associated equipment before accessing fastener assemblies. Use a properly sized open-end or box wrench to tighten the jam nut against the primary nut. Follow applicable mechanical codes and torque requirements specified by the equipment manufacturer for the assembly.
