Value Collection 329130PS Hex Jam Nut 1/2-13 Grade 2 Steel

Product Description

The VALUE COLLECTION 329130PS is a 1/2-13 UNC hex jam nut manufactured from Grade 2 steel with a bright, uncoated finish. Jam nuts are thinner than standard full hex nuts, making them the correct choice for lock-nut applications where two nuts are threaded against each other to prevent loosening under vibration or dynamic load. The right-hand thread engages standard 1/2-13 UNC fastener systems. At 5/16 inch in height and 3/4 inch across the flats, this nut fits a standard 3/4-inch wrench or socket. Grade 2 carbon steel suits general-purpose mechanical and structural fastening work across trade and industrial settings.

This jam nut is used in general mechanical assembly, HVAC equipment mounting, plumbing fixture support, electrical enclosure hardware, and similar trade applications where a low-profile locking nut is required on a 1/2-13 UNC threaded rod, bolt, or stud. The uncoated finish is appropriate for dry or protected indoor environments. Installers working in corrosive or exterior environments should evaluate whether a coated or stainless alternative is required for the application.

Key Features

• Jam-nut profile at 5/16 inch height for low-profile lock-nut applications
• 1/2-13 UNC right-hand thread for compatibility with standard inch-series fasteners
• Grade 2 steel construction for general-purpose mechanical fastening
• Bright, uncoated finish with 3/4 inch across-flats dimension fitting standard tooling
• Sold individually; minimum order quantity is 50 pieces

Compatibility

Designed for use with standard 1/2-13 UNC threaded fasteners including bolts, rods, and studs following Unified National Coarse thread specifications.

Installation Notes

Installation requires a 3/4-inch wrench or socket. When used as a jam nut, thread it against a primary nut and torque both nuts against each other to secure the assembly. Verify thread engagement and ensure no cross-threading before applying final torque. Always follow applicable mechanical and structural codes for the specific installation environment.
