Description

Hex Top Lock Nuts 18/8 Stainless Waxed 1/2-20 offer durable, rust-resistant fastening for mechanical assemblies and outdoor projects. Crafted from 18/8 stainless steel and finished with a waxed coating, these lock nuts deliver smooth threading, superior corrosion resistance, and reliable vibration resistance in a wide range of environments.

Key features

  • Material: 18/8 stainless steel for excellent corrosion resistance in wet or outdoor environments
  • Finish: Waxed coating to improve lubricity and thread protection during installation
  • Type: Hex Top Lock Nut provides a secure, vibration-resistant locking action
  • Thread Size: 1/2-20 UNC (Unified National Coarse) standard for broad compatibility
  • Applications: Ideal for automotive, machinery, structural, and outdoor fastenings

Why choose waxed stainless lock nuts?

Waxed locking nuts help reduce galling and facilitate smoother installation, while the 18/8 stainless construction delivers long-lasting corrosion resistance. The hex-top design makes it easy to tighten with common tools, and the locking feature helps prevent loosening under vibration and thermal cycling.

Usage tips

  • Pair with corresponding bolts or studs of the same 1/2-20 UNC size.
  • Tighten to the manufacturer's torque specification to avoid over- or under-tightening.
  • Store in a dry environment to preserve the wax coating and extend service life.
