Value Collection R52000340 Split Lock Washer 9/16 in

Product Description

The VALUE COLLECTION R52000340 is a split lock washer designed for use with 9/16 inch fasteners. Made from 18-8 stainless steel with an uncoated finish, it provides reliable resistance to corrosion and oxidation in demanding environments. The washer measures 0.564 to 0.574 inches inner diameter, up to 0.965 inches outer diameter, and 0.141 inches thick. Split lock washers function by biting into the mating surface and fastener underhead to resist loosening under vibration and torque. This hardware is commonly installed by HVAC technicians, plumbers, electricians, and millwrights wherever a secure, corrosion-resistant fastener assembly is required.

This split lock washer is suited for use in mechanical, plumbing, electrical, and HVAC assemblies where stainless steel hardware is specified to prevent galvanic corrosion or rust. Its inch-system dimensions make it a standard fit in domestic trade applications. Typical use cases include equipment panels, pipe hangers, conduit supports, and structural fastener assemblies in both residential and commercial settings.

Installation Notes

Install with the split ends oriented to bear against the fastener underhead and mating surface before torquing the fastener.
