Applications & Selection Guide
Carbon-steel structural plate washers to DIN 7989. Large-diameter, thicker washers for steel-to-steel bolted connections — typically with DIN 7990 construction hex bolts. Listed for M10–M30.
Use over slotted holes, on thinner plate, or wherever the drawing calls for a plate washer rather than DIN 125. They are not HV (DIN 6916) washers and should not be mixed into a pretensioned HV set. Pair with DIN 7990 bolts and appropriate nuts as specified.
Add sizes and quantities to the quote cart with coating and destination. Matching construction bolts can be included.
