M12 Galvanized steel Square washer 50 x 50 x 3

M12 square plate washer, 50mm x 50mm x 3mm thick, in Galvanized stainless steel. Bigger footprint than a standard round washer, so it spreads the load better and stops the bolt head or nut pulling through timber. Good for decking joists, balustrade posts, ground screw fixings, and any structural timber connection where you need more bearing area than a round washer gives you. 3mm thick, so it won't flex or dish under load. Stainless steel means it won't rust or stain the timber around it. Specs: Size: 50mm x 50mm Thickness: 3mm Bolt size: M12 Material: Stainless steel Galv Hole: centred, sized for M12 bolt/coach screw Sold individually
