Value Collection 498000 Hex Jam Nuts Steel Unc 50-pack

Product Description

The VALUE COLLECTION 498000 is a pack of 50 steel hex jam nuts designed for general fastening applications where a low-profile locking nut is required. Hex jam nuts are thinner than standard hex nuts and are commonly used as locknuts to secure a primary nut against loosening under vibration or torque. These nuts follow the Unified National Coarse (UNC) thread standard with right-hand threading. Installers in mechanical, HVAC, plumbing, and electrical trades use jam nuts when securing threaded rod, bolts, or fastener assemblies in panels, brackets, and equipment frames.

These hex jam nuts are suited for light mechanical assembly, equipment mounting, and fastener lockout applications across residential and commercial settings. The UNC thread standard makes them compatible with the most common inch-series threaded fasteners used in North American trade work. The steel construction provides adequate strength for typical panel and bracket fastening tasks. Each package contains 50 nuts, making them practical for service vehicles and job-site inventory.

Key Features

• Steel construction provides durability for general mechanical fastening
• UNC (Unified National Coarse) thread standard for broad inch-series compatibility
• Right-hand thread direction matches standard fastener convention
• Low-profile hex jam nut design functions as a locknut against primary fasteners
• Sold in a 50-piece pack for efficient job-site and service inventory use

Compatibility

Designed as a general-purpose replacement or stock hex jam nut for use with standard UNC inch-series threaded fasteners in mechanical, HVAC, plumbing, and electrical assembly applications.

Installation Notes

Hex jam nuts are installed by a wide range of trades as locknuts on threaded rod, machine bolts, and equipment fasteners. Always de-energize or shut down the equipment being serviced before working on fastener assemblies. Use an appropriately sized open-end or box wrench to torque the jam nut snugly against the primary nut. Do not overtighten, as the thin profile of a jam nut has lower torque tolerance than a standard full hex nut.
