Value Collection 112NJP Hex Jam Nut 1-1/8-7 Un Steel

Product Description

The VALUE COLLECTION 112NJP is a 1-1/8-7 UN hex jam nut machined from steel and intended for use in threaded fastener assemblies where a thin locking nut is required. Measuring 2.25 inches across flats and 0.84 inches high, this right-hand-thread jam nut is supplied uncoated and is well suited for general mechanical, industrial, and trade applications. It is installed by maintenance technicians, millwrights, and mechanical contractors working on equipment assemblies, structural connections, and piping or HVAC support frameworks that require a secondary nut to lock a primary fastener in position.

This jam nut is a standard UN-thread fastener used wherever a low-profile locking nut is needed on 1-1/8-7 UN threaded rod, bolt, or shaft. Typical applications include equipment mounting, adjustable support structures, vibration-sensitive assemblies, and mechanical linkages across residential, commercial, and light industrial settings. The right-hand thread direction follows standard installation conventions, making it compatible with the vast majority of threaded fastener applications encountered in the field.

Key Features

• 1-1/8-7 UN thread size with right-hand thread direction for standard fastener compatibility
• Steel construction provides strength and durability in mechanical assemblies
• Hex jam nut profile at 2.25 inches across flats accepts standard open-end or box wrenches
• Low-profile height of 0.84 inches functions as a locking secondary nut against a primary fastener
• Uncoated finish suitable for dry indoor environments and assemblies where coating is not required

Compatibility

Designed for use with 1-1/8-7 UN threaded fasteners including threaded rod, bolts, and shafts using right-hand UN thread form.

Installation Notes

Installation is performed with a standard open-end or combination wrench sized for 2.25-inch across-flats hex geometry. The jam nut is threaded onto the fastener and tightened against the primary nut to prevent loosening under load or vibration. Ensure the mating threaded component uses a compatible 1-1/8-7 UN right-hand thread before installation. Follow applicable mechanical codes and torque guidelines for the assembly type and load requirements.
