Anchor bolts form the structural connection between a building's superstructure and its concrete foundation, transferring tensile, shear and bending loads safely into the ground. At Hyrax Fasteners, every anchor bolt is forged and machined from certified carbon steel, high-tensile steel or stainless steel billets, then heat-treated to deliver consistent yield strength across the full bolt length.

Our anchor bolt range covers L-shaped, J-shaped and straight foundation bolts in diameters from M10 to M48, supplied with matching hex nuts and washers. Threads are rolled rather than cut to retain material grain structure and maximise fatigue resistance under cyclic structural loading, making these fasteners suitable for seismic and wind-load design conditions.

Surface protection is selected to match the exposure environment: hot-dip galvanizing for outdoor and corrosive sites, electro-zinc plating for indoor structural work, and black oxide for embedded, non-exposed applications. Every batch is dimensionally inspected and proof-load tested before dispatch, with mill test certificates issued on request for project documentation and statutory compliance.
