Reliable corrosion resistance – Thanks to zinc-plated alloy steel

Zinc plating over alloy steel forms a protective layer that reduces oxidation and surface rust. The alloy composition improves durability compared with plain steel.

Longer service life in damp or exposed conditions means fewer replacements and less maintenance for gates and outdoor fittings.

Secure load distribution – With a flat bearing surface

Flat washers provide a broad, even bearing surface that spreads clamping force over a larger area around the screw or bolt head. This reduces localised stress and prevents pull-through in softer materials.

Reduced risk of damaged timber or loose fixings, resulting in firmer joints and tidier finishes on carpentry and metalwork.

Predictable compatibility – With standard DIN/ISO sizing

Manufactured to DIN EN ISO 125 and ISO 7089 dimensions for M12 hardware, ensuring consistent internal and external diameters and fit. Dimensions noted as M12 (13mm x 24mm).

Simple selection for repairs and projects, with reliable fit for M12 bolts and nuts across common hardware ranges.
