DIN 436:2024 Wood Construction Square Washer

DIN 436:2024 Wood Construction Square Washer is used for broad bearing support in timber bolted connections. The square outside shape provides a wide support surface, helping distribute tightening force from the nut or bolt head over the wood surface.

The product can be used in wooden beam joints, timber trusses, bridge timber elements, fence structures, and large wooden assemblies. Its geometry creates a stable clamping area on timber components and reduces the risk of local indentation, cracking, and loosening.

Different sizes, thicknesses, and corrosion-protection treatments can be selected according to bolt size, wood strength class, and exposure environment, making it suitable for long-term structural connections and repair reinforcement.
