Product overview
Hardened steel lock washer prevents nuts and bolts from turning, slipping, and coming loose because of vibration and torque. These fasteners contain split ends that help "lock" into the mating material, thus providing a locking feature when tightened beneath a nut.
  • Commonly used in applications where two pieces of wood are being joined together
  • Split ends grip the material surface to prevent loosening during vibration
  • Zinc plating offers moderate protection against rust and corrosion
  • Prevents a nut, bolt, or screw of the same finish and size from pulling through material
  • These washers are approved for use in any project involving treated lumber
