Lock washer with two lugs is a fastener used to lock hex bolts and nuts, mainly on corners and faces. The larger foot bends down, behind the edge of the part that is clamped, and the smaller one bends up, pressing against the face of the nut or bolt cap, which makes it impossible to unscrew them.
Scope DIN 463 is widely used in mechanical engineering, construction and manufacturing industries for good fastening of structural elements, prevents self-unscrewing of threaded connections under dynamic impact and vibration.
Material stainless steel. The A4 steel grade allows you to use fasteners with significant temperature changes and in an aggressive and humid environment.
No coverage.
