Drop-in Anchor Carbon Steel Yellow Passivated



Drop-In Anchors are perfect for suspending threaded rod from concrete ceilings.

The Steel Drop-In Anchor (also sometimes referred to as Knockins or HKDs) is an internally threaded expansion anchor complete with a pre-assembled integral expander plug. The anchor is expanded with a matching setting tool designed to protect internal threads while driving the pre-fitted plug to the end of the anchor. The tapered plug is precisely matched to the internal configuration of the anchor body to develop maximum expansion against the walls of the hole, and each steel anchor body has 4 slots on the leading end which allows it to expand.

During installation, as the plug is driven into the bottom of the anchor, the steel shell is forced outward in four directions compressing against the walls of the anchor hole.
