Description
The dyna bolt (expansion anchor / wedge anchor) is a mechanical anchor that fixes fittings and equipment to cured concrete without needing to cast anything in beforehand. Drilled into hardened concrete and tightened, its sleeve expands to grip the hole tightly, providing a strong, immediate fixing for railings, machinery, brackets and fixtures. This makes it the go-to anchor for retrofitting and attaching to existing concrete structures.
Dyna bolts (expansion anchors) are supplied in a range of diameters and lengths, with the correct drill-hole size and embedment specified for each. Matching the anchor size and embedment to the load and the concrete is what makes the fixing reliable. Confirm the sizes and drill requirements in the specifications below.
