1-1/4″ Conquest Split Lock Washer – Plain Finish

This 1-1/4″ split lock washer is engineered to help secure large-diameter bolts used in structural, industrial, or mechanical applications. Its helical spring design generates tension under load, providing a mechanical lock that resists loosening from vibration or shifting. The plain steel finish makes it ideal for indoor or low-corrosion environments where rugged fastening is key.

Install under bolt head or nut and torque to compress the washer, engaging the spring-loaded locking force.
