Anchor Detail

Nomenclature
da = 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 Instruction for UltraCon SS4

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 UltraCon SS4 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.

HWH = Hex Washer Head, TFH = TrimFit® Flat Head
Hex Head UltraCon ss4 Anchors are measured from below the washer while flat head UltraCon ss4 anchors are measured end to end. To select the proper minimum anchor length, determine the embedment depth required (e.g. required to obtain desired load capacity). Then add the thickness of the fixture, including any spacers or shims, to the embedment depth.
