Value Collection C52000812 High Collar Split Lock Washer

Product Description

The VALUE COLLECTION C52000812 is a high collar split lock washer designed for use with 3/8 inch screws. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this washer provides reliable vibration resistance and load distribution in bolted assemblies. The high collar profile offers increased bearing surface compared to standard split lock washers, helping to maintain clamp load under dynamic or high-vibration conditions. Inside diameter ranges from 0.382 to 0.393 inches, maximum outside diameter is 0.553 inches, and thickness is 0.125 inches. Each package contains 50 washers.

This washer is suited for mechanical, industrial, and trade assembly applications where 3/8 inch fasteners are used and vibration resistance is required. Common installation scenarios include HVAC equipment mounting, electrical panel and enclosure assembly, plumbing fixture attachment, and general structural fastening. The 18-8 stainless steel construction offers corrosion resistance appropriate for both indoor and moderate outdoor environments. This package quantity of 50 makes it practical for service techs and contractors stocking field kits.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends oriented to bite into both surfaces as the fastener is tightened. Ensure mating surfaces are clean and free of debris before assembly. Stainless steel fasteners can be prone to galling — apply appropriate anti-seize compound when pairing with stainless bolts and nuts in high-torque applications. Follow applicable mechanical and electrical codes for the specific assembly being serviced.
