DIN 7980 split washers differ from DIN 127 due to their smaller external diameter. Therefore, they fit the small head of cheese-head and hexagon socket screws (DIN 84, 85, 912) and are especially well-suited to countersinking applications.
Field of Application:
Only suitable for bolts of strength class ≤ 5.8. For higher strength classes, Schnorr lock washers (item no. 0493/0493 0) or Nord-Lock lock washers (item no. 0435 0) should be used.
