Value Collection 330150PS Jam Nut 9/16-12 Unc Grade 2

Product Description

The VALUE COLLECTION 330150PS is a 9/16-12 UNC jam nut manufactured from Grade 2 steel with a zinc-plated finish. Jam nuts are thin hex nuts used as locknuts, threaded against a primary nut to prevent loosening under vibration or dynamic load. This nut features a right-hand thread and measures 7/16 inches across the flats with a height of 5/16 inches. It is suited for general-purpose mechanical fastening in HVAC equipment, plumbing supports, electrical enclosures, and light structural assemblies where a standard-depth nut is not required.

This jam nut is used in a wide range of trade applications including securing threaded rod assemblies, pipe hangers, and equipment mounting hardware. The zinc coating provides basic corrosion resistance for indoor and semi-protected outdoor installations. The 9/16-12 UNC thread size is a common coarse-thread standard found on fasteners throughout residential and commercial mechanical systems. Licensed tradespeople and maintenance technicians routinely use jam nuts in this size for vibration-sensitive installations.

Key Features

• 9/16-12 UNC coarse right-hand thread for broad fastener compatibility
• Grade 2 steel construction suitable for general-purpose load applications
• Zinc-plated finish provides basic corrosion protection
• Thin jam-nut profile at 5/16 inches height for use as a locknut
• 7/16 inches across flats fits standard hex wrenches and sockets

Compatibility

Designed as a general-purpose 9/16-12 UNC jam nut compatible with any matching coarse-thread bolt or threaded rod of the same diameter and thread pitch.

Installation Notes

Jam nuts are installed by threading a primary nut to the desired position, then threading the jam nut against it and tightening the two nuts toward each other with two wrenches to create a locking friction load. Use an appropriately sized open-end or box wrench to avoid rounding the flats. Inspect threads on both the bolt and nut for damage before installation. No special tools or trade license are required, but follow applicable mechanical codes for structural or load-bearing applications.
