Product description

This B40-8 lock washer works alongside the matching B41-8 flat washer to keep an 8-series bolt from backing out under the constant vibration a lift experiences during daily cycling. Its split-ring design bites into both the bolt head and the flat washer beneath it, converting rotational vibration into resistance instead of allowing the fastener to loosen. SVI manufactures this washer from spring-tempered steel so the ring retains its bite even after repeated torque-and-release cycles, unlike a softer washer that can flatten out over time. Fitting it correctly during a rebuild is a small detail that has an outsized effect on how long the joint stays tight between service intervals.
