Value Collection 2525 Hex Jam Nut 7/16-20 Unf Stainless Steel

Product Description

The VALUE COLLECTION 2525 is a 7/16-20 UNF hex jam nut machined from stainless steel with a right-hand thread direction. Jam nuts are low-profile locking nuts used to secure a primary nut in place or to lock a threaded fastener at a fixed position along a shaft or rod. This nut measures 11/16 inches across the flats and 1/4 inch in height, making it a standard thin-profile hex nut suitable for tight axial spaces. The uncoated stainless steel construction provides corrosion resistance without the dimensional variation introduced by plating or coating. It is installed by plumbers, HVAC technicians, electricians, and millwrights wherever vibration or adjustment requires a secondary locking nut on a threaded assembly.

This jam nut is suited for light mechanical assemblies, fluid system fittings, threaded rod applications, and equipment mounting hardware in both residential and light commercial settings. The 7/16-20 UNF thread pitch is a fine-thread specification, which provides finer adjustment resolution and higher thread engagement strength per unit length compared to coarse-thread variants. Stainless steel construction makes this nut appropriate for environments with moisture exposure or mild chemical contact, including plumbing chases, mechanical rooms, and outdoor equipment installations.

Key Features

• 7/16-20 UNF fine-thread specification for precise adjustment and strong thread engagement
• Low-profile jam nut design at 1/4 inch height for use in space-constrained assemblies
• 11/16 inches across flats for standard hex wrench or open-end wrench fitment
• Uncoated stainless steel construction for corrosion resistance without coating buildup on threads
• Right-hand thread direction compatible with standard fastener tooling and assemblies

Compatibility

Designed as a standard 7/16-20 UNF hex jam nut for use in threaded rod, fastener locking, and mechanical assembly applications requiring a fine-thread stainless steel thin nut.

Installation Notes

Installation is performed by hand-threading onto a 7/16-20 UNF male-threaded fastener or rod, then tightening against a primary nut using two opposing wrenches to achieve a locked position. Power down or depressurize any system before servicing threaded fasteners within live assemblies. Do not overtighten jam nuts against soft or aluminum male threads, as the fine thread form is susceptible to galling under excessive torque. Follow applicable mechanical or plumbing codes for fastener material selection in wet or chemically exposed environments.
