Cast-in-place bolts
At their most basic, cast-in-place anchors are straight bolts inserted into concrete foundations. Often, the inserted end includes a nut and a small steel plate to increase its holding strength. The other end is corkscrewed. This end connects concrete or steel structures to the foundation. Multiple variants have been developed from this basic design, specialising by application. One variety is the headed anchor bolt. Headed anchor bolts have a hexagonal or square head, providing more support than the basic design.
Eye foundation bolts
Eye foundation bolts bend into an eye shape at one end and are attached to a cross piece at the other for easy setting into a concrete foundation. These pieces are your best choice for firmly securing cables and steel rods, helping structural elements withstand strong movements and pressure while allowing secured components to move if required.
Bent-bar anchor bolts
Instead of securing cables, the typical application of J and L type foundation bolts is to hold together heavy structural elements. These anchor bolts bend at one end to provide firmer support when set into wet concrete and see use across the construction industry and civil engineering projects. The L-type foundation bolt has industrial applications, such as anchoring tooling, equipment and structural columns to concrete structures. The L-type bolt is a fantastic choice for lighter-weight uses.
Swedge bolts
Swedge bolts are round bars with a threaded end and a swedged end. ‘Swedge’ refers to the serrated indentations made on the bar, which considerably improves the grip of the foundation bolt in the concrete. Swedge bolts are among the strongest foundation bolt types.
Plate bolts
Plate bolts resemble a capital T. Inserted upside-down into wet concrete, one end of the plate bolt is corkscrewed, allowing a nut and steel plate to connect to concrete foundations. Plate-type foundation bolts are popular components for holding down heavy equipment and have a variety of applications across the construction industry.
Lewis foundation bolts
Unlike other foundation bolt types, lewis’s foundation bolts are particularly effective for one specific task: moving heavy stones and slabs. These bolts are tapered at one end and include keys, allowing easy removal. Inserted into concrete slabs or drilled into heavy stones, lewis foundation bolts can then be attached to cranes or winches. This can either be done by securing a key to the bolt’s end or forging the lewis bolt initially as a headed anchor bolt. They then allow easy lifting and moving. After moving the heavy object, these bolts can be removed and reused.
