Self Locking Counter Nut - A2 Stainless DIN 7967
Tightens against a primary nut to secure it firmly into place. Compressing the counter nut against the primary nut causes the internal teeth / barbs of the counter nut to pinch the threads of the bolt, locking both the counter nut and the primary nut into place. Once in place, the primary nut cannot be accidentally unscrewed.
