available in every style and material. Check with us for specs, prices and availability.
Tooth Lock Washers
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.
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.
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 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"
