Hardened Metal Stamping Parts Steel Internal Toothed Lock Washer DIN 6797 Type J
Stamped internal toothed lock washer with good anti-slip purpose and widely used to various metal or non-metal conjunction , when put a toothed lock washer onto the surface of material , the teeth will be insert into it under pressure , and the opposite side will be touched the surface under head of screw or bolt . internal toothed lock washer will provides enough grip to prevent screw or bolt slipping after installed .
The specifications for internal toothed lock washers are from 1.7 to 31 normally , the total height of lock washers are usually two times the thickness of material .
