Drill It.
Red Head makes installation simple, accurate and reliable.
Use It.Set It.
Simply drill the hole to the same
diameter as the outside diameter
of the anchor being used.
After drilling, clean the hole. Drive
the anchor flush with the surface
of the concrete. Expand the anchor
using the setting tool provided in
each master carton. The anchor is
fully expanded when the shoulder
of the setting tool is flush with the
top of the anchor.
The Red Head anchor is now set.
The flush embedment lip keeps
the suspended threaded rod
at the same length for a clean,
finished look.
ITW Red Head offers an
entire line of easy to install
drop-in anchors

* The tabulated values are for RX anchors installed at a minimum of 12 diameters on center and minimum edge distance of 6 diameters for 100 percent anchor efficiency. Spacing and edge distance may be reduced to 6 diameters spacing and 3 diameter
edge distance provided the values are reduced 50 percent. Linear Interpolation may be used for intermediate spacings and edge margins.
* Allowable values are based upon a 4 to 1 safety factor. Divide by 4 for allowable load values.
