MBS Series Bearing Lockwashers – Metric, Stainless Steel
The MBS series is the stainless steel metric bearing lockwasher, matched to the stainless KMS locknut. Corrosion at the tang is what kills a lockwasher — a pitted tang cracks when bent — so in wet or chemically aggressive service the stainless pair is the specification that actually holds.
