Minerallac 40325 1/4" Flat Cut Washer, Zinc-Plated Steel Hardware

Minerallac 40325 1/4" Flat Cut Washer, Zinc-Plated Steel

The Minerallac 40325 is a 1/4" flat cut washer manufactured from steel with a zinc-plated finish for reliable corrosion resistance. Designed for assembly around a bolt or screw, this washer sits between the bearing surface of the fastener and the part to which it is attached, helping distribute clamping load evenly across the joint and preventing surface damage under torque. With an outside diameter of 0.64", an inside diameter of 0.296", and a thickness of 0.08", this washer is precisely sized to fit 1/4" bolt applications commonly found in electrical panel work, conduit support hardware, and general fastening tasks across commercial and industrial job sites. The silver zinc-plated finish gives the washer a clean, uniform appearance while helping guard against rust in indoor electrical and mechanical assemblies. Supplied in a jar for convenient bench-top access, easy dispensing, and simple inventory control, the 40325 is a practical bulk-hardware solution for electricians, panel shops, and maintenance crews who need a dependable flat washer on hand.

Why Minerallac?

Minerallac supplies steel, zinc-plated fastening hardware built for consistent, reliable performance on electrical and mechanical assemblies. The 40325 flat cut washer's precise 0.64" outside diameter, 0.296" inside diameter, and 0.08" thickness ensure a proper fit for 1/4" bolt applications, while the zinc-plated finish helps guard against corrosion over the life of the installation. Packaged in a convenient jar, it's an easy addition to any electrician's or maintenance crew's hardware stock, delivering dependable performance job after job. Electricians and panel shops rely on this washer for consistent bearing-surface protection whenever bolts, screws, or lugs are torqued into place on switchgear, enclosures, or conduit supports, since a uniform washer diameter and thickness keeps clamping force even across every joint in a bulk hardware run.
