Spring lock washers, often manufactured to DIN 127 and ASME B18.21.1 standards, are critical components used to maintain bolt tension and resist loosening due to vibration or dynamic load. Their helical shape allows them to exert constant spring pressure between the nut and substrate, providing a locking effect in bolted joints.
TAIMING, a specialized manufacturer of fasteners and industrial hardware, recommends using zinc-plated carbon steel spring lock washers for general mechanical assemblies and Grade 304 stainless steel for corrosive or outdoor environments. Sizes typically range from M3 to M30, matching standard bolt dimensions and tolerances.
Engineering evaluations from TAIMING indicate that Type B square-end washers offer better seating and rotation resistance compared to Type A. When paired with Grade 8.8 or Grade 10.9 bolts, they ensure higher preload stability in machinery exposed to dynamic stress.
Correct installation torque is vital. Over-compression may reduce the washer’s elasticity and locking performance. TAIMING’s recommendation is to follow matched torque specs and avoid reusing deformed washers to maintain joint integrity.
