Grade 10.9 Belleville Spring Washer M3.5 Bevel Black Phosphate Din6796

M3.5 disc spring washer Anti Loosening conical lock washer belleville washer DIN6796 with phosphate for bolted connection

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.

The special shape (formed like a disc spring) enables the 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.

The design and manufacture method of these washers make them offer great forces in short travels. It should never be forgotten that their elastic capacity is limited. This is why they are preferred to work under static loads, where they can maintain the pressure over time.
