DIN 6798 A Serrated Lock Washers, With External Teeth

DIN 6798 A are external toothed washers that can provide excellent locking.
They are particularly effective on flat bearing surfaces that are larger than their outer diameter.

Sizes Ø from 3 to 16 mm feature overlapped teeth to ensure an excellent clamping. Internal hole of sizes 6, 8x14, 12 and 16 features a restricted tolerance compared to the standard in order to reduce the play between washer and screw.
