M20 Wood Construction Washer - 23mm ID x 80mm OD | DIN 1052 | A4 Stainless Steel
Designed for marine timber work, jetties and boardwalks, this DIN 1052 wood construction washer provides a larger contact area than a standard flat washer. Manufactured from A4 Stainless Steel to DIN 1052, it helps distribute fastener load across the timber and reduce the risk of bolt heads or nuts pulling into softer wood. The A4 marine-grade material is particularly suited to coastal, marine and high-moisture timber applications where enhanced corrosion resistance is required.
What Are Wood Construction Washers?
Wood Construction Washers are large-diameter flat washers designed specifically for timber assemblies. Their wider surface area spreads the clamping load from bolts, coach screws or nuts across more of the wood which helps reduce crushing, indentation and fastener pull-through.
Common Applications
- Heavy Timber Projects: Supports larger structural connections where standard flat washers may not provide enough load distribution.
- Retaining Structures: Helps spread clamping force in heavy timber walls, sleepers and structural support projects.
- Boardwalks and Jetties: A4 Stainless Steel options suit timber structures exposed to saltwater, high humidity and coastal conditions.
- Timber Frame Construction: Spreads bolt or coach screw load across beams, posts and joists to support stronger structural joints.
