Red Head IRHWS-3446 Itw Wedge Anchor Carbon 3/4" x 4 3/4"

The Red Head IRHWS-3446 is an ITW Red Head wedge anchor, carbon style, 3/4 inch x 4-3/4 inch, supplied 10 per box.

A wedge anchor is a mechanical expansion anchor for concrete, and understanding how it works explains how it is correctly installed. The anchor is a threaded stud with a tapered cone at its buried end and a wedge clip around it. Drilled into a hole and tightened, the nut pulls the stud upward, the cone is drawn into the clip, and the clip is forced hard against the wall of the hole. The anchor holds by friction and mechanical interlock against the concrete.

That mechanism has consequences that installers ignore at their peril. The hole diameter must be exactly what the anchor specifies — an oversized hole means the wedge never gets the grip it needs. The hole must be cleaned of dust before the anchor goes in, because drilling dust between the wedge and the concrete is a lubricant. The anchor must be set to the specified torque, since that torque is what expands the wedge. And an anchor that spins rather than tightening has failed and cannot be fixed by tightening it more.

At 3/4 inch by 4-3/4 inch this is a substantial structural anchor.

Applications include structural steel base plates, equipment mounting, racking, and heavy fixings into concrete.

Verify the anchor's load rating and embedment against the engineering requirement.
