M5 Washer for Wood Construction DIN 440 Type R in A2 Stainless - DIN 440

These washers for timber or wood construction are of a robust design that distribute the force a bolt head and nut apply to the wood when tightened. By spreading the load over a larger surface area, the large diameter washer will protect the timber around the fixing point from being crushed or splitting. This type R variant features the usual round hole, but the standard does feature a square holed type (type V). These timber construction washers are especially useful for softwood and aluminium, and their additional support will aid the structural integrity of the joint. The increased bearing surface of the washer will also help accommodate the movement in the wood as the timber expands and contracts with changes in humidity.
