Plain Washers

Description

HBS Fasteners manufactures a comprehensive range of Plain Washers, the most widely used component in the fastening industry. A plain washer serves two primary purposes: it distributes the pressure of the fastener over a wider area to prevent damage to the workpiece, and it provides a smooth, flat surface for the nut or bolt head to bear against. Whether you are working with soft plastics, wood, or high-strength steel, our plain washers ensure that your joints remain tight and your surfaces remain intact.

Technical Specifications

• Standard: Available in all major international standards:

  • DIN 125 / ISO 7089: Standard Flat Washer (Type A).

  • DIN 9021 / ISO 7093: Large OD (Fender) Washer for extra load distribution.
