DIN128B Wave Spring Lock Washers

The 304 stainless steel Wave Spring Lock Washers is an elastic washer in the shape of a saddle (arc-shaped curve). It complies with the German standard DIN 128B. The products produced by JINGHONG are made of high-quality 304 stainless steel (A2), formed by stamping. The surface is treated with natural passivation, featuring excellent rust prevention and corrosion resistance properties. Its unique saddle-shaped arc surface structure generates continuous elastic restoring force when under pressure, providing pre-tightening compensation for the connection pair and effectively resisting vibration loosening. The specifications cover M3 to M12, and are compatible with corresponding metric bolts/screws.

Product Feature

The 304 stainless steel material possesses natural passivation properties, featuring excellent rust and moisture resistance. It is suitable for humid, outdoor and general chemical environments, and there is no risk of coating peeling. Its saddle-shaped arc structure deforms under pressure and generates rebound force, which can continuously compensate for the thread gap and effectively suppress loosening caused by vibration. Its performance is superior to that of ordinary flat washers. Its thin design occupies less space than standard spring washers and is suitable for compact assembly positions, without significantly increasing the connection height. The elastic contact can disperse compressive stress and reduce indentation and damage to thin plates or soft surfaces. It covers specifications from M3 to M12, is compatible with hexagonal bolts, internal hexagonal screws, self-tapping screws and other fasteners of the same specification, and is widely applicable in various scenarios, with extremely strong versatility.
