Midwest Fastener No. 10 Split Lock Washers

The Midwest Fastener No. 10 Split Lock Washers provide reliable tension and holding power to keep threaded fasteners secure under heavy vibration. Designed with a split helical cut that deflects under load, these washers exert continuous spring pressure against the fastener head and mating surface to help prevent accidental loosening. Manufactured from high-grade stainless steel, these split lock washers deliver superior resistance against rust and corrosion, making them suitable for indoor, outdoor, marine, and harsh environmental applications. They provide an effective fastening solution across automotive, mechanical, construction, and general repair projects.
