Stainless Steel Belleville Washers Conical M10 Spring Anti Loosening

M10 disc spring washer Anti Loosening conical lock washer belleville washer DIN6796 with phosphate for bolted jointing

The washers grip bolts more tightly than split and tooth lock washers and have a continuous body that can rotate in either direction. The main application of these elements is to secure screwed joints, maintaining constant tension between them. Temperature variations and vibrations may produce expansion or contraction in the joint between the screw and nut, which produces the joint loosening over time. The force generated in the screw joint by the washer once compressed maintains a tension that compensates those effects and avoids the total loss of tension, maintaining a firm and stable joint between the screw and nut over time.
