“During the late 1970's and early 1980's, the Tapcon masonry screw was initially introduced to tap threads into concrete,” stated Bob Carlisle, President and founder of Concrete Fastening Systems, Incorporated. “The combination of the screw's capacity to have threads hard enough to cut into concrete and to also remove the dust created during the application created an innovative design that revolutionized the concrete fastening business.”

“The original Tapcon masonry diameters of 3/16” and ¼” remain highly popular,” he explained. “Now added to these widely used fasteners are the large size diameter concrete screws (LDT) which have been developed in diameters of 3/8”, ½”, 5/8 “ and ¾”. “

· Buildex, a division of ITW RedHead, manufactures the Tapcon brand masonry fastener in the United States.
· The hole drilled into the masonry material is critical and must meet the tolerance specifications to meet minimum holding values.
· Carbide tipped drill bits that meet ANSI standards must be used to drill the hole in the masonry, and they must be used with a hammer drill that is set in the hammer and rotation mode.
· The 3/16” tapcon requires the use of a 5/32” while the 1/4” requires the use of a 3/16”.
· The lengths of the Tapcon masonry anchor are the same for both diameters.
· The 1/4” comes in two additional lengths of 5” and 6”.
· The lengths available for both diameters are 1-1/4”, 1-3/4”, 2-1/4”, 2-3/4,3-1/4, 3-3/4' and 4”.

· The Tapcon masonry anchor comes in both a carbon steel that is Climaseal® coated in a blue color and in the 410 stainless steel that is also coated with Climaseal® in a silver color.
em bedment Depths
· The em bedment depth of the Tapcon masonry anchor is critical both in the minimum and maximum em bedment depth.
· The Tapcon masonry anchor must be installed into the ba se material a minimum of 1” and the maximum em bedment is 1-3/4”. Below the 1” minimum em bedment depth the tapcon masonry anchor will not achieve required holding values.
· em bedment depths of more than 1-3/4” will create installation problems, such as when the Tapcon masonry anchor becomes stuck, unable to be removed or inserted further.
· The harder and the more abrasive the ba se material, the further from the maximum em bedment of 1-3/4” should be attempted.

Head st yle
· There are two different head st yles that the Tapcon masonry anchors are manufactured: the hex washer slotted and the flat phillips countersunk.
· Both diameters come in both different head st yles and require different size tools for installation. The 3/16” hex head requires a 1/4” nut runner; the 1/4” requires a 5/16” one. The 3/16” phillips flat head needs a #2-bit tip and the 1/4” needs a #3-bit tip.
· When measuring the lengths of the Tapcon masonry anchor, the hex head is measured from under the head and the flat heads are measured as an overall length including the head.
