[100 PKG] Hex Lock Nuts NU Nylon Inserts 18/8 Stainless 1/4-20

Hex Lock Nuts NU Nylon Inserts 18/8 Stainless 1/4-20 provide secure, vibration-resistant fastening with a built-in nylon insert that helps prevent loosening in challenging environments.

Constructed from 18/8 stainless steel for outstanding corrosion resistance and durability, these hex lock nuts are designed to perform in wet, outdoor, and high-humidity applications.

The nylon insert delivers a positive locking action, gripping the bolt thread as you tighten and resisting backing out under vibration or dynamic loads. This makes them ideal for equipment, machinery, and assemblies subject to movement.

Thread size: 1/4-20 — a common coarse thread suitable for a range of standard bolts and fasteners.

Why choose Hex Lock Nuts NU — combines stainless steel strength with nylon locking, delivering reliable, maintenance-friendly performance in a compact locknut design.

Applications — ideal for automotive, industrial machinery, marine hardware, outdoor equipment, and electronics assemblies where secure fastening and corrosion resistance are important.

To install, thread the nut onto a compatible bolt to the manufacturer’s torque specification. The nylon insert remains in place to provide locking action; if the nut shows signs of wear or the assembly is subjected to repeated, high-cycle loading, consider replacement to maintain optimum locking performance.
