Description

Enhance fastening reliability with Lock Washers External Tooth Steel Black Oxide #1/2. These external-tooth lock washers are engineered to resist loosening under vibration by biting into the bolt head and the mating surface for a secure, clamped connection.

Key features

  • Material: Steel
  • Finish: Black oxide
  • Type: External tooth lock washer
  • Size: #1/2
  • Applications: Automotive, machinery, and general hardware assemblies

Benefits

External tooth design provides a positive bite into surfaces, helping prevent loosening under vibration and shocks. The black oxide finish adds mild corrosion resistance and delivers a low-profile appearance for assemblies where both performance and aesthetics matter.

Installation tips

  • Place the washer between the bolt head or nut and the mounting surface.
  • Ensure seating surfaces are clean, flat, and free of debris for full bite.
  • Pair with compatible fasteners to maximize retention in high-vibration environments.
