Titen® Concrete Screws

Purchase Tapcon Anchors

The brand name used by Simpson Anchor Systems for their concrete & masonry screw is the Titen®. The Titen® concrete screw is manufactured to fasten a wide variety of items to concrete, brick or block base material. The Titen® concrete screw should be used in dry, non-corrosive environments. Studies have shown that hardened fasteners can have performance problems if they are used in applications where the environment is corrosive and/or wet.

Titen® Material and Finish

This masonry and concrete screw is made from a heat-treated carbon steel that is zinc plated with a baked on ceramic coating.

Diameter of Screw

Titen® screws are available in two diameters of 3/16” and 1/4”. Large diameter Titen® concrete screws called the Titen® HD are available. The Titen® HD comes in diameters ranging from 3/8” to 3/4”.

Length of Screw

The 3/16” Titen® is available in seven different lengths ranging from 1-1/4” to 4”. The 1/4” Titen® screw comes in nine different lengths from 1-1/4” to 6”. The 1/4” is available in the 5” and 6” length.

Head Style

The Titen® concrete screw comes in two different head styles of the hex slotted washer head and the flat phillips countersunk. The 3/16” diameter Titen® has a 1/4” hex slotted washer head and the 1/4” Titen® has a 5/16” hex slotted washer head. The phillips drive on a 3/16” Titen® has a #2 phillips drive and the 1/4” has a 3# phillips driver.

Colors Available

The flat headed phillips Titen® screw is available in the standard blue color as well as in white and silver.

Hole Diameter

Both diameters of Titen® screws require a specific size hole to be drilled into the base material. Hole size is critical because a hole drilled too large in the base material will reduce or eliminate the load capacity of the Titen® concrete and masonry screw. The 3/16” diameter Titen® requires a 5/32” hole and the 1/4” Titen® requires a 3/16” diameter hole in the base material. The correctly sized bit for each Titen® concrete and masonry screw is provided in each box of 100 screws. To meet hole tolerance specifications, the carbide bit must meet ANSI standards for the designated diameter.

Hole Depth

The hole that is drilled in the base material must be a minimum of 1/2” deeper into the base material than the Titen® screw will penetrate. This extra 1/2” allows space for any dust to collect during the installation process in order to prevent the screw from bottoming out in the hole and creating problems.

Length of Screw

The minimum length of the Titen® concrete and masonry screw can be determined by adding the thickness of the material being fastened plus 1”. The maximum length of the Titen® that can be used is equal to 1-1/2” plus the thickness of the material being fastened. The hex headed Titen® length is measured from under the head and the flat-headed Titen® length is measured including the head.

Critical Spacing and Critical Edge Distance

For the Titen® masonry screw to achieve adequate holding values in the base material, the screws need to be spaced a minimum distance from each other and also a minimum distance from an unsupported edge of the concrete. The minimum distance is a factor of the diameter of Titen® being used in the particular application. A 3/16” Titen® concrete screw must not be placed closer than 2-1/4” from each other and no closer than 1-1/8” from an unsupported edge of the concrete. The 1/4” Titen® needs to be spaced 3” from each other and no closer than 1-1/2” from an unsupported edge of the concrete.

Thickness of Base Material

The base material that the Titen® concrete and masonry screw is placed must be 1.5 times thicker than the embedment depth of the Titen® screw.

Titen® Usage in Treated Lumber

The Titen® screw is suitable for use in non-ammonia formulations of CCA, ACQ-C, ACQ-D, CA-B SBX/DOT and zinc borate. The Titen® screw should be used in dry, interior environments only. Caution should be taken not to damage the ceramic coating during installation.

Installation Instructions

1. With the correct diameter, carbide tipped bit and a hammer drill, drill hole in the base material 1/2” deeper than the screw will penetrate.

2. Clean the hole with compressed air.

3. Insert Titen® concrete screw through the hole in the fixture and into a hole in the base material. Turn Titen® slowly until the head of the screw is tight against the fixture.
