Minerallac 40335 3/8" Flat Cut Washer, Zinc Plated Steel

Minerallac 40335 3/8" Flat Cut Washer, Zinc Plated Steel

The Minerallac 40335 3/8" Flat Cut Washer, Zinc Plated Steel is a fundamental hardware component designed for use around bolts and screws in electrical and mechanical assemblies. Constructed from zinc-plated steel with a silver finish, this flat cut washer sits between the bearing surface of a fastener and the part it secures, helping distribute clamping stress evenly across the joint. With a 3/8" fit, an outside diameter of 0.827" and an inside diameter of 0.419", this washer is engineered to span larger clearance holes while maintaining a low profile thickness of 0.08". This flat washer design protects the substrate material from damage by spreading fastener load across a wider bearing area, reducing the risk of surface deformation or pull-through in soft materials. Sold by the jar for convenient bulk handling on the jobsite or in the shop, it's a staple item for electricians, contractors, and maintenance professionals who need reliable fastener support hardware on hand for panel builds, enclosure assembly, conduit hangers, and general mechanical fastening tasks. The jar packaging keeps washers organized and easy to dispense one at a time, reducing waste and keeping small parts from getting lost in a toolbox or parts bin. Because it is manufactured to consistent diameter and thickness tolerances, the 40335 washer performs predictably across repeated installations, making it a dependable choice for anyone stocking a service truck, panel shop, or maintenance department with essential fastening hardware.
