Schnorr M5 x 9 x 0.9mm Type VS Safety Washer Serrated Zinc Plated 200pk

Engineered for critical bolted joints, Type VS Safety Washer Serrated Zinc Plated holds bolt preload against vibration and dynamic loading through a tensioning cam action rather than friction or thread deformation. The wedge-locking design means tighter, not looser, joints under load. Used across rail and mining equipment, wind energy installations, offshore and marine fastening, heavy plant and machinery, and structural engineering connections. Part of the Nord-Lock range of vibration-resistant fasteners trusted by engineers in safety-critical applications. Designed to deliver consistent locking performance through demanding service conditions.
