Description
Locking Washer MB33-SKF is a circular steel device designed to prevent loosening of fasteners (screw, bolt or nut) subjected to vibrations and alternating loads. Inserted between the head and the support surface, it creates an elastic tension that keeps the clamping force constant, avoiding “self-loosening”. The surface finish (zinc-plated, burnished or passivated) increases corrosion resistance and optimizes adhesion, ensuring reliability and durability in mechanical applications.
