Workshop Hardware offers a wide selection of hardware that is both durable and authentic. Our Metric Stainless Steel Nylon Insert Flange Nut Set offers 87 nuts, in varying sizes, to ensure you have what you need for your next project – no matter how big or small. Flange nuts are nuts that have a wide flange at one end that acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. This means they are made to hold heavy-duty machine parts, manufacturing equipment, and more. You can feel confident that you are getting reliable, quality crafted products that will take you from one job to the next from Workshop Hardware.
