L-Shaped Foundation Anchor Bolts
L-shaped foundation anchor bolts are cast into concrete foundations so that machinery, columns and base plates can be bolted down after the concrete has cured. The 90° bend at the embedded end works like a hook, mobilising the surrounding concrete against pull-out. Also called bent anchor bolts, foundation bolts or cast-in bolts.

Frequently Asked Questions
How are L-shaped foundation anchor bolts installed?
The L-bend is cast into the wet concrete footing with the threaded end projecting, or set into a grouted pocket. The concrete cures around the bend so the bolt resists pull-out, then the structure or machine base is bolted down on the thread.
