Waxed Cardboard Cones for Holding Down Bolts

Our square plate washers are manufactured to provide secure and even load distribution for holding down bolts and structural anchor systems. Ideal for use in concrete foundations, steel column bases, and heavy-duty construction projects, these washers enhance stability and prevent pull-through under high loads.

Available in M16, M20, and M24 sizes, our washers are precision-engineered for compatibility with standard bolt configurations. Each washer is produced from high-quality galvanised steel, offering superior corrosion resistance and long-term durability — even in demanding site conditions.

Designed to meet UK engineering and construction standards, BoltBox square plate washers ensure a strong, reliable connection between baseplates and foundation bolts.
