Engineered to solve problems
ecosyn®-SEF combines a self-locking nut with an integrated conical spring washer and large contact surface. Bossard engineers designed ecosyn®-SEF as a multifunctional fastening element for the safe connection of electrically conductive contacts, especially in the high-voltage range. ecosyn®-SEF is also excellently suited for purely mechanical connections requiring Design for Manufacturability by combining several mechanical fastener elements into one.
