The contact lock washer is a product specifically designed for the industry. It complies with the NFE 25-511 and SN 70093 standards, making it highly reliable and effective in securing wobble-prone screws.

This lock washer is particularly well-suited for use on slot fasteners, where screws are dynamically cross-loaded and require high biasing forces. It guarantees secure fastening with its grooved surface and positive spring action.

The contact lock washer comes in different forms to accommodate various applications. Form S is narrow and ideal for small headrests, while Form M is average and suitable for normal headrests. For large pressure transmission surfaces and slot fasteners, Form B is recommended. Additionally, Form K, with its serrated surface and contact teeth, is specifically designed for electrically conductive connections (SN 70093).

In terms of operation, the contact lock washer provides a form-fitting locking mechanism, ensuring that the screw remains securely in place. It is manufactured by VOSSLOH-VERBINDUNGSELEMENTE, INH. MICHAEL VOSSLOH E.K., a reputable German producer.
