Overview

The Minerallac 70725SS316USJ is a 1/4" x 1-1/4" fender washer constructed from Type 316 stainless steel. This material offers superior corrosion resistance, making it ideal for applications in marine environments, chemical processing, and other corrosive settings where standard stainless steel may not suffice. Type 316 stainless steel is known for its enhanced resistance to pitting and crevice corrosion due to its molybdenum content. Fender washers are characterized by their larger outer diameter compared to their inner diameter. This design effectively distributes the load over a wider surface area, preventing damage to softer materials or finishes and reducing the risk of pull-through in bolted assemblies. The 1/4" inner diameter is suitable for use with standard 1/4" bolts and screws, while the 1-1/4" outer diameter provides the necessary surface area for load distribution. Manufactured by Minerallac Company, a trusted name in electrical and industrial hardware, this fender washer is designed for heavy-duty applications requiring long-term durability and reliability. The product is conveniently sold in jars, facilitating bulk purchasing for projects and inventory management. The SKU 70725SS316USJ clearly identifies this specific fastener for easy reordering. Its US origin signifies adherence to manufacturing standards.
