Internal Thread Screw KH-EZ 1/4" x 2-1/2" I 1/4"

This ultimate‑performance screw anchor features an internally threaded head for fastening standard ANSI‑tolerance threaded rods into cracked or uncracked concrete and other base materials. Constructed from zinc‑plated carbon steel, it installs quickly without hammering or high‑accuracy torque wrenches, thanks to efficient cutting edges that reduce drilling effort and enable overhead use. Approved by FM, ICC‑ES (including seismic and cracked‑concrete applications), and LABC, it meets IBC 2018 requirements and works with standard 1/4″ drill bits. Not reusable, this pre‑fastening anchor delivers high productivity and reliability where code compliance is critical.
