Tooth Lock Washers

  • EXTERNAL TYPE: Should be used wherever possible, as the tapered, twisted teeth are on the largest radius to provide maximum torsional resistance. Best used with a fastener having a round, pan, binding or other head large enough to make contact with the washer teeth. External tooth washers are also available with left hand or alternately twisted teeth for special applications.
  • INTERNAL TYPE: Recommended for use with smaller head screws such as fillisters. Also recommended for applications where it is best to hide the teeth either for appearance or to prevent scratching or snagging.
  • HEAVY DUTY INTERNAL TYPE: Recommended for use with heavy bolts and nuts, and with heat treated bolts usually on castings and heavy machinery or equipment.
  • FOLDED RIM TYPE WASHERS: A modification of the standard Red Earth External Tooth Lock Washer with the folded rim providing additional body strength to resist extreme fastening stresses.
  • COUNTERSUNK TYPE For use with flat or oval head screws having either 82º or 100º countersunk angles. Also available with internal teeth or flanged to provide locking action with concealed teeth.
  • EXTERNAL-INTERNAL TYPE Should be used where a larger bearing surface is desired, for oversized or elongated holes or as an insert between two adjustable pieces where the adjustment - either rotational or longitudinal - must be maintained after the original setting. Because of the added biting teeth, External-Internal lock washers are ideal for electrical bonding purposes.
  • PYRAMIDAL TYPE Recommended for applications requiring very high tightening torques. This type has a unique design which provides both locking teeth and rigidity, yet is resilient under heavy loads. Both square and hexagonal shapes are available.
  • DOME TYPE Available with either plain or toothed periphery. Because they distribute the load over a wide area, Dome Type washers are recommended for use with soft or thin materials where considerable force is needed for holding.
  • Also recommended for oversize or elongated holes. Plain periphery washers are recommended where surfaces should not be marred by biting teeth. Toothed periphery washers should be used where additional protection against shifting is required
  • DISHED TYPE: Available with plain or toothed periphery. Recommended for the same applications and purposes as Dome Type washers, but should be used where resiliency rather than rigidity is most important.
  • Both Dome and dished Types are crowned or arched to support the internal teeth so they can lock into the bolt head or nut. Flat rim Dished Type Lock Washers are a variation of the plain periphery and are ideal for plastic surfaces, electrical components and similar applications. Has small O.D. for limited space
  • WIDE RIM TYPE: Recommended for use with large diameter screw and bolt heads and for spanning oversize holes where extreme torques are not required
  • ALTERNATE TWISTED TOOTH TYPE: Provide both clockwise and counter clockwise locking action. Resists rotation in either direction
  • NARROW RIM TYPE: Ideal for small head screws and for applications where appearance or O.D. clearance are determining factors
  • PIPE LOCK WASHERS: Made especially for locking nuts having an extreme internal diameter in relation to the O.D. Examples are found in lamp and instrument board assemblies
  • TYPE "B" TOOTH FORM: This alternative tooth form is available in most styles and types. Preferred by some for heavy duty applications
