Related specificationsHow does an Ankerbolt differ from a throughbolt?
A throughbolt expands against the hole wall; the Ankerbolt cuts a thread into it. That makes it expansion-free - usable closer to edges - removable, and suitable for cracked as well as non-cracked concrete in the assessed ranges. Drill the listed hole size, blow it clean and drive the bolt; no plug, no sleeve.
