GENERAL INFORMATION
AGGRE-GATOR®
300 Series Stainless Bi-metal Concrete and masonry fasteners
PRODUCT DESCRIPTION
The Aggre-Gator anchor is a bi-metal screw anchor for light to medium duty applications in concrete and masonry block base materials. The Aggre-Gator is fast and easy to install and provides a neat, finished appearance. Aggre-Gator anchors provide excellent corrosion resistance in demanding applications, such as those in exposed environments.
GENERAL APPLICATIONS AND USES
- Exposed anchoring/wet areas
- Hurricane shutters
- Windows and screens
- Masonry facade support anchors (e.g. brick tie anchors)
- Aluminum enclosures
- Curtain wall & window wall support anchors
- Pressure-treated wood (e.g. ACQ)
FEATURES AND BENEFITS
+ High in-place value over life of structure
+ High strength and ductility
+ stalgard Gb coating creates greater galvanic compatibility in dissimilar metal applications involving aluminum
+ Anchor design and thread profile provides quick cutting during installation

Anchor Detail
Nomenclature
d = Diameter of anchor
dbit = Diameter of drill bit
dh = Diameter of fixture clearance hole
hnom = Minimum embedment depth
h = base material thickness The minimum value of h should be 1.5hnom or 3″ whichever is greater
ho = Minimum hole depth
INSTALLATION INSTRUCTIONS
Installation Instructions for Aggre-Gator
Step 1
Using the proper drill bit size, drill a hole into the base material to the required depth, ho, which is a 1/4-inch deeper than the minimum embedment depth, hnom.
Step 2
Remove dust and debris from the hole during drilling (e.g. dust extractor) or following drilling (e.g. suction, forced air) to extract loose particles created by drilling.
Step 3
Attach a Ultracon+ installation socket tool for the selected anchor size to a percussion drill and set the drill to rotary only mode. Mount the screw anchor head into the socket. For flat head versions a bit tip must be used with the socket tool.
Step 4
Place the point of the Aggre-Gator through the fixture into the pre-drilled hole and drive the anchor in one steady continuous motion until it is fully seated at the proper embedment. The driver will automatically disengage from the head of the screw.

| 1. Tabulated load values are for anchors installed in uncracked concrete. Concrete compressive strength must be at the specified minimum at the time of installation. 2. Ultimate load capacities must be reduced by a minimum safety factor of 4.0 or greater to determine allowable working load. Consideration of safety factors of 10 and higher may be necessary depending upon the application such as life safety or overhead. 3. These values are for tests conducted with 1″ x 4″ nominal (3/4″ max. thick) treated southern yellow pine attached to concrete; the listed embedment is into the concrete. 4. These values are for tests conducted with 2″ x 4″ nominal (1-1/2″ max. thick) treated southern yellow pine attached to concrete; the listed embedment is into the concrete. | |||||||||||||

| HWH = Hex Washer Head, TFH = TrimFit® Flat Head Hex Head Aggre-Gator anchors are measured from below the washer while flat head Aggre-Gator anchors are measured end to end. To select the proper minimum anchor length, determine the embedment depth (e.g. required to obtain desired load capacity). Then add the thickness of the fixture, including any spacers or shims, to the embedment depth. | |||||
