Value Collection HLWIS062 High Collar Split Lock Washer 25 Pack

Product Description

The VALUE COLLECTION HLWIS062 is a high collar split lock washer designed for use with 5/8 inch screws. Manufactured from steel with an uncoated finish, this washer provides reliable resistance to fastener loosening under vibration and dynamic loads. The split lock design bites into both the fastener bearing surface and the mating material, maintaining clamp load in demanding mechanical assemblies. With an inner diameter ranging from 0.635 to 0.65 inches, a maximum outer diameter of 0.923 inches, and a thickness of 0.203 inches, these washers meet standard dimensional requirements for 5/8 inch hardware applications. Supplied in a pack of 25.

These high collar split lock washers are suited for general mechanical, structural, and industrial fastening applications. The high collar profile provides additional thread engagement compared to standard split lock washers, making them a preferred choice where fastener security under load cycling is a priority. Typical installation scenarios include equipment assembly, structural steel connections, and maintenance applications across HVAC, plumbing, electrical, and general trade work where 5/8 inch fasteners are used.

Installation Notes

Installation is performed by placing the washer onto the fastener shank between the fastener head and the mating surface before torquing to specification. Ensure the split ends are properly seated against the bearing surfaces to achieve the intended locking effect. No special tools are required beyond standard hand or power wrenches appropriate for the fastener size. Inspect washers for deformation or damage before reuse, as a compressed or flattened split lock washer will not provide adequate locking force.
