3/4" Screw, 0.79" ID, Spring Steel Internal Tooth Lock Washer MPN:SIWIS0750HDUSA-

The 3/4 Screw with Spring Steel Internal Tooth Lock Washer is perfect for applications requiring extra holding power and preventing loosening under vibration or shock load conditions such as machinery, automotive, aerospace industries amongst others. The combination of the two components allows users to create a locking mechanism when tightening the screw into a through-hole in one piece of material while simultaneously washing the inside surface with a secondary piece - effectively wedging or camming it against its mating piece. The 0.790 ID of this product allows ample space between the threads for optimal engagement, ensuring longevity and superior performance even in heavy duty environments subjected to high stress loads while maintaining minimal insertion clearance demands for thin material.
