The VALUE COLLECTION 330170BR is a 5/8-11 UNC jam nut manufactured from Grade 2 steel with a zinc-plated finish. Jam nuts are thin hex nuts used to lock a standard nut in place or to secure a fastener assembly where reduced stack height is required. At 3/8 inches tall with a 15/16-inch width across flats, this nut follows right-hand thread direction and meets standard UNC thread specifications. It is a general-purpose fastener suited for mechanical assemblies, structural connections, and equipment fabrication where a Grade 2 steel fastener is appropriate.
This jam nut is used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture support, electrical enclosure assembly, and general mechanical work. The zinc plating provides basic corrosion resistance suitable for indoor and light-duty outdoor environments. With a 5/8-11 UNC thread size, it is compatible with standard 5/8-inch threaded rod, bolts, and hardware commonly found in residential and commercial construction and mechanical systems.
Designed for use with standard 5/8-11 UNC threaded fasteners including bolts and threaded rod in general mechanical, structural, and equipment-mounting applications.
Install with a standard 15/16-inch combination wrench or socket. When used as a locking jam nut, torque the primary nut to the required value first, then tighten the jam nut against it while holding the primary nut stationary. Ensure mating threads are clean and free of debris before installation. Minimum order quantity is 25 units.
