Overview

Minerallac Company SKU 70315J #10 flat cut washers are precision-engineered stainless steel fasteners designed for uniform load distribution in general-purpose applications. Made from Type 18-8 stainless steel, these washers provide excellent corrosion resistance against moisture and mild chemicals, making them ideal for electrical, HVAC, and construction environments where reliability is critical. The flat cut design ensures a broad bearing surface that prevents damage to fastened materials by distributing clamping force evenly. Each washer features an outside diameter of 0.515 inches and an inside diameter of 0.227 inches, precisely matching #10 bolt sizes for secure fitment. Supplied in a convenient 100-piece jar, these washers offer bulk storage and easy access for high-volume assembly operations. The 18-8 stainless steel composition delivers non-magnetic properties and long-term durability without requiring additional finishes. Common applications include securing electrical panels, mounting HVAC components, and general construction where stainless steel fasteners are specified. These washers are not intended for high-temperature or high-stress environments beyond standard mechanical fastening requirements. The flat cut profile differs from split or lock washers by providing a smooth, continuous surface for even pressure distribution across joined materials.
