NOTES
Unless otherwise noted, recommended load rating is 1/4 of above Ultimate Load data.
Next to the screw used, “T” stands for Tensile force, and “S” stands for Shear force.

1
2" embedment
2
depending on actual dim. of drill used
3
2" embedment of threaded insert for use in hollow applications. Drilled pilot hole approx. 3/16" larger.
4
Tensile value is recommended at 1/6 tested
5
Shear value is recommended at 1/4 tested
6
for use in solid applications. Drilled pilot hole approx. 3/16" larger.
7
For hollow concrete block, use of “Block Plug” is required
RESULTS
Alligator Anchor
Plastic anchor that’s inserted into predrilled hole. As fastener is screwed into anchor, it expands uniformly around screw and elongates from 1-3/16" to
over 2". The threads of the screw cut into the anchor, and the anchor spreads to fill into the crevices and pores of the mansonry.
Benefits: Can be used in solid concrete, hollow blocks, or even drywall. It is inexpensive and does not require special installation or drilling tools.
Drawbacks: Anchors cannot be reused, and a separate screw must be used together with the anchor.

Rawl Lok/Bolt and Hilty HLC
Metal expansion sleeve anchors that are screwed into predrilled holes of same diameter and depth. Anchor is inserted into hole through fixture, then
tightened with wrench or screw driver. As screw is tightened, it pulls metal sleeve outward from the hole, thus expanding the sides and wedging it into
the concrete.
Benefits: Can be used in solid concrete, hollow blocks, or brick. Does not need special drill bit. Single piece system so no extra assembly is needed.
High holding strength. Short embedment. Anchor may possibly be reused if sleeve and nylon compression ring are not damaged.
Drawbacks: These anchors are more expensive than Alligator anchors and self tapping masonry screws. They’re not as strong in dense concrete as
Alligator anchors.

Rawl Tapper and ITW Tapcon
High strength steel screw that self taps into predrilled hole. Hole must be drilled with specially toleranced drill bit that is mated with that particularly sized
screw. A special installation tool is required. It’s used to attach to the drill bit, and also has a torque slip mechanism to fasten the screw without over
tightening it.
Benefits: Can be used in solid concrete, hollow blocks, or brick. It’s inexpensive, easy to use and does not need separate anchors. Can be reused.
Drawbacks: A special installation tool and drill bit are required. These fasteners are not as strong as Alligator anchors.
