Conical spring washers DIN 6796
Hardened, bright, oiled or mechanically galvanised.
The special shape (formed like a disc spring) enables the conical spring washer to achieve a high spring effect. The spring force resulting from the flattening load washer amounts to 70–90% of the corresponding contact pressure of a screw of grade 8.8–10.9.
Conical spring washers are used to compensate for subsidence formation in screw connections and to prevent a loosening or unfastening of the connection. The locking effect is purely frictional.
