Tooth Lock Washers

Internal Tooth
This style is recommended for applications where the teeth must be hidden under the screw head. Internal type lock washers provide maximum locking efficiency where finished appearance is a factor.

External Tooth
This style offers the greatest locking efficiency and should be used wherever possible. Optimum locking action is assured since teeth maintain largest area of contact with nut or screw and work piece.

Internal-External Tooth
These washers are for use where a larger bearing surface is desired, for oversize or elongated screw holes. Extra teeth make it ideal for electrical grounding purposes.

Countersunk External Tooth
Countersunk type lock washers are for use with flat or oval head screws in either 82 degree or 100 degree countersunk angles. Some sizes are available with internal teeth.

Standard Sizes
Standard sizes range from #2 diameter to 1-5/16" bolt diameter.

Internal: #2 to 1=5/16"
External: #3 to 1"
Internal-External: #6 to 5/8"
Countersunk: #2 to 1/2"
