Description

Hex Lock Nuts Nylon Inserts 18/8 Stainless Waxed 4/40 deliver secure, vibration-resistant fastening for a wide range of assemblies. These nuts combine a standard hex nut body with a built-in nylon insert that forms a locking action once the screw threads through.

Made from 18/8 stainless steel, they offer excellent corrosion resistance and durability in moisture-prone, outdoor, or chemical-exposure environments. The waxed nylon insert further enhances performance by reducing friction during installation and improving long-term locking capability.

  • Locking mechanism: Built-in nylon insert creates a secure, vibration-resistant lock.
