External Tooth Lock Washer 400 Series Stainless Steel

External Tooth Lock Washer 400 Series Stainless Steel

External Tooth Lock Washer 400 Series Stainless Steel fasteners are designed to provide superior locking action and resistance to loosening in bolted and screwed assemblies. Featuring multiple external teeth around the outer diameter, these washers create a strong gripping action between the fastener and the mating surface. This design helps prevent loosening caused by vibration, shock, and movement, making external tooth lock washers a popular choice for industrial, electrical, automotive, and manufacturing applications.

Durable 400 Series Stainless Steel Construction

Manufactured from 400 Series stainless steel, these lock washers offer a unique combination of strength, hardness, and corrosion resistance. Unlike austenitic stainless steel grades, 400 Series stainless steel is heat treatable and provides increased wear resistance and mechanical strength. This makes it particularly suitable for applications requiring both secure fastening and durability under load.

400 Series stainless steel lock washers are commonly used in environments where moderate corrosion resistance and excellent mechanical performance are required. They are well-suited for machinery, equipment, and assemblies exposed to vibration and repeated use.

External Tooth Design for Enhanced Holding Power

The external teeth are designed to bite into the mating surface and the underside of the fastener head, creating a positive locking action. This helps maintain consistent clamping force and improves resistance to loosening caused by vibration or operational movement.
