BGL MS Lock Washer for HM Nuts
The BGL MS lock washer sits over an HM nut on a large adapter sleeve and holds it in place with a screw. It stops the nut from backing off under vibration or rotation, so the bearing stays properly fitted on the shaft. This type of washer belongs to large adapter sleeve assemblies where the nut needs a secure lock.
