Professional Applications & Engineering Value
This split lock washer is engineered to solve the critical industrial problem of fastener loosening under intense vibration and dynamic loads. Its high-carbon steel composition and Rockwell C38 hardness provide the necessary spring force and resistance to deformation, ensuring a constant preload on the 3/4" screw. The standard split lock design bites into both the nut and the workpiece, creating a powerful locking action that is essential in machinery, automotive assemblies, and heavy equipment. This makes it an indispensable industrial washer for maintaining the integrity of bolted joints, preventing downtime, and enhancing the safety of mechanical systems where reliability is non-negotiable.
