Schnorr 17 x 2mm HS Load Washer DIN 267 | AIMS Industrial

HS Load Washer DIN 267 Geomet 321B is engineered to secure bolted joints against vibration, dynamic load and thermal cycling through a wedge-locking cam action. Unlike friction-based locking solutions, the cam angle of the washer is greater than the bolt thread pitch, so any rotation actually increases clamping tension on the joint. Suited to heavy machinery, rail rolling stock and infrastructure, mining and quarry equipment, wind turbines and renewable energy installations, offshore and marine assemblies, and structural engineering connections where bolt failure is not an option. Manufactured by Nord-Lock to engineering standards trusted by critical-fastening engineers worldwide. Built to maintain preload through repeat vibration and dynamic loading.
