Description
Our Flat Washers are engineered to provide even load distribution, improved fastening stability, and protection for surfaces during assembly. Available in both DIN 125 (standard form) and BS 4320 (large outside diameter) specifications, these washers are suitable for general and heavy-duty fastening applications.
Designed to pair with bolts, nuts, threaded rods, and screws, they reduce pressure on surfaces, prevent pull-through, and enhance long-term fastening performance.
