Industrial Nylon Insert Jam Lock Nut Grade 2 USS Coarse Zinc 1/4-20 Nylon Insert Lock Nut

Description:

The Wurth Grade 2 Nylon Insert Jam Lock Nut is a thin-profile locking fastener designed for securing threaded assemblies in industrial, automotive, construction, and maintenance applications. Featuring a zinc-plated steel body with a nylon locking insert and USS coarse 1/4-20 threads, these jam nuts are commonly used where vibration resistance and reduced nut height are required. Maintenance technicians and assembly professionals use nylon insert jam nuts to prevent loosening on bolts, threaded rods, and machine assemblies.

Applications:

These Wurth nylon insert jam lock nuts are used in machinery, automotive systems, industrial equipment, electrical enclosures, fabrication projects, and maintenance operations where a low-profile locking nut is needed to resist vibration loosening. Nylon insert jam nuts are commonly installed as secondary locking nuts or in confined spaces where standard-height lock nuts cannot fit. Coarse USS threading provides durable fastening for general-purpose industrial use.
