Split lock washers in 18-8 stainless steel to ASME B18.21.1. A split ring with a helical twist that flattens under the nut or bolt head and keeps spring tension on the joint, helping it resist loosening from vibration. Medium (regular) section, the standard lock washer for bolts and cap screws. 18-8 (A2-70) stainless resists rust and staining outdoors and in wash-down areas. A black oxide finish gives a dark, low-glare look over the stainless. Sold in production-volume bulk packs.
