Quarter-Turn Retainer, Size 4, Stainless Steel Stainless Steel Starlock Washer Fasteners 0.16in ID 0.47in OD Internal Tooth Lock Washers Push-On Locking Speed Clip Fasteners

Toothed star lock washer is a commonly used fastening element, used in mechanical equipment to realize the fastening and fixing of parts. It has a certain special structure and working principle and has certain requirements for fastening requirements.
Toothed star lock washers are made of spring steel and have a certain degree of elasticity and hardness. This enables it to provide a certain fixing force through elastic deformation when subjected to external forces. At the same time, its surface presents a toothed structure, which can increase the friction between it and the parts, thus realizing a stronger fixing effect. When used, the toothed star lock washer needs to be selected according to the specific fastening requirements of the appropriate specifications and dimensions. Generally speaking, its inner diameter should match the outer diameter of the part to ensure that it can be correctly set into the part. At the same time, its outer diameter should be slightly larger than the hole diameter of the part to ensure that it can be fully expanded during assembly and close contact with the part, to realize a better fixing effect.
