Value Collection 329050PR Hex Jam Nut 1/4-20 Grade 2

Product Description

The VALUE COLLECTION 329050PR is a 1/4-20 UNC hex jam nut manufactured from Grade 2 steel with a bright, uncoated finish. Jam nuts are thin-profile hex nuts used to lock a standard nut in place or to secure a fastener assembly where vertical space is limited. This nut measures 7/16 inches across the flats and 0.156 inches in height. It features a right-hand thread and is suited for general-purpose mechanical and structural fastening applications. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and industrial service regularly stock this fastener for field repairs and panel assembly work.

This jam nut is appropriate for residential and light commercial applications where a low-profile locking nut is required. It is commonly used in equipment mounting, bracket assemblies, threaded rod installations, and any situation where a jam or check nut is specified. The 1/4-20 UNC thread size is one of the most widely used coarse-thread standards in North American trade work, making this nut a common addition to service van fastener stock.

Key Features

• 1/4-20 UNC right-hand thread for compatibility with standard coarse-thread hardware

Installation Notes

Jam nuts are typically installed by threading the jam nut against a standard hex nut and tightening the two against each other to create a locking effect. Use an appropriately sized wrench to hold the jam nut while torquing the primary nut. This fastener does not meet military specifications and should not be used in applications requiring mil-spec hardware. Always verify thread engagement and inspect for cross-threading before applying final torque.
