Questions about this item
Will these M20 split lock washers fit the 20.2 mm bolt holes on my existing flanges?
Yes, the inside diameter is 20.2 mm and they are made for M20 bolt sizes, so they match standard M20 hardware.
How can I verify the washers meet the DIN 128 A standard after installation?
Check that each washer is curved spring steel with a zinc-plated gray finish, 3.20 mm thick and 33.6 mm outside diameter — those dimensions confirm DIN 128 A compliance.
Does the pack of 50 include any bolts or nuts, or just the washers?
The box contains only the 50 split lock washers; bolts and nuts must be purchased separately.
