Value Collection 329430PS Hex Jam Nut 7/16-20 Unf Grade 2

Product Description

The VALUE COLLECTION 329430PS is a 7/16-20 UNF hex jam nut manufactured from Grade 2 steel with a bright, uncoated finish. Jam nuts are thin hex nuts used primarily as locknuts to secure a standard nut in place or to adjust and lock threaded rod assemblies. This nut features a right-hand thread and measures 11/16 inches across the flats. At 0.02 pounds, it is a lightweight fastener suited for general mechanical and structural fastening applications where Grade 2 steel meets the load requirements. Installation is straightforward and does not require specialty tooling beyond a standard open-end or box wrench.

This jam nut is used across a wide range of trade and industrial applications including HVAC equipment assembly, plumbing support hardware, electrical panel mounting, and general equipment maintenance. It is appropriate for residential and light commercial settings wherever a 7/16-20 UNF fine-thread fastener is needed for locking or adjustment purposes. Grade 2 steel suits low-to-medium strength applications. Sold individually per package, with a minimum order quantity of 50 pieces.

Key Features

• 7/16-20 UNF fine-thread specification for precise thread engagement
• Grade 2 steel construction for general-purpose fastening applications
• Bright uncoated finish — suitable for interior or dry-environment use
• Right-hand thread direction, standard for the majority of fastening applications
• Jam nut profile allows use as a locknut or for threaded rod adjustment
• 11/16 inch across flats — compatible with standard SAE wrenches

Compatibility

Designed as a general-purpose replacement or supplemental jam nut for any assembly requiring a 7/16-20 UNF right-hand thread hex nut in Grade 2 steel.

Installation Notes

Install using a standard open-end, box-end, or combination wrench sized to 11/16 inches. When used as a locknut, thread the jam nut against the primary nut and hold one while tightening the other to create the locking effect. Do not exceed the torque capacity appropriate for Grade 2 steel at this thread size. For structural or load-bearing applications, verify that Grade 2 steel meets the engineering requirements before use.
