This product is suitable for all general applications. Washers with an enlarged outer diameter (SP) have the same inner diameter as the standard washers. They are designed to be used together with flanged bolts and nuts (ISO 4161,4162) on oversized and slotted holes, or on sensitive surfaces and soft materials.
Washer is through hardened to ensure it is harder than the bolt and contact surface. It is treated with Delta Protekt®, a surface coating that provides excellent corrosion protection. Nord-Lock washers work with all common bolt grades such as 4.8, 5.6, 8.8, 10.9 and 12.9.
