Overview

Minerallac 1/4" Flat Cut Washer (SKU: 70325) is a precision-engineered Type 18-8 stainless steel washer designed for superior load distribution and clearance hole spanning in industrial and electrical applications. Manufactured by Minerallac Company, this flat cut washer is engineered to fit 1/4" bolts with an inside diameter of 0.281" and a nominal thickness of 0.050" (±0.007"). Supplied in jars of 100, this washer provides a silver-finished, corrosion-resistant solution for demanding environments where moisture, mild chemicals, or chloride exposure are concerns. Flat washers are essential components in mechanical assemblies, serving to distribute the load of a fastener across a larger surface area while also spanning oversized clearance holes. The 18-8 stainless steel composition ensures excellent resistance to rust, corrosion, and oxidation, making it ideal for outdoor, marine, and industrial settings. Unlike standard washers, flat cut washers provide a uniform bearing surface that minimizes stress concentrations on connected parts, reducing the risk of deformation or failure over time. This washer is RoHS compliant, ensuring it meets strict environmental regulations for hazardous substances. It is not UL listed but is fully compliant with California Proposition 65, with no known chemicals associated with the regulation. The product is distributed in standard quantities of 100 per jar and 1200 per master carton, with a country of origin of the USA. For applications requiring enhanced chloride resistance, consider Minerallac’s Type 316 stainless steel flat washers, which offer superior performance in harsh environments. Key applications include electrical panel assemblies, machinery mounting, structural connections, and any scenario where a durable, non-magnetic washer is required. The 18-8 designation refers to the alloy composition (18% chromium, 8% nickel), providing a balance of strength, ductility, and corrosion resistance. This washer is a cost-effective solution for engineers and contractors seeking reliable, long-lasting performance without the premium cost of higher-grade alloys.
