Square Section Spring Washer DIN 7980

Our Square Spring Washers, or Split Washers as they are also known, are manufactured to DIN 7980 from high performance stainless steel, which provides an excellent level of resistance and strength across medium to heavy loads. These washers act like a spring, becoming compressed during fastening, counteracting work loosening on short bolts that are subject to thrust.

Most commonly used in conjunction with Bolts, Machine Screws and Nuts, these products are used to prevent loosening of the fasteners. We also offer Rectangular Section Spring Washers.

Our Rectangular Section Spring Washers are available in A2 (Equivalent to 304) or A4 (Equivalent to 316 Marine Grade) Stainless Steel in metric sizes from M3 to M30. For our full selection of sizes and materials see the product table displayed below, or get in touch with a member of our staff.
