Product Overview

The Titen HD anchor is a high-strength screw anchor for concrete and masonry. It is designed for optimum performance in both cracked and uncracked concrete. The high-strength, easy-to-install Titen HD anchor has been tested and shown to provide outstanding performance in cracked and uncracked concrete under both static and seismic loading conditions. The self-undercutting, non-expansion characteristics of the Titen HD anchor make it ideal for structural applications, even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.
  • Qualified for static and seismic loading conditions
  • Thread design undercuts to efficiently transfer the load to the base material
  • No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits
  • Testing shows the Titen HD installs in concrete with 50% less torque than competitor anchors
  • Hex-washer head requires no separate washer and provides a clean installed appearance
  • Carbon steel Titen HD utilizes a specialized heat-treating process that creates tip hardness for better cutting without compromising the ductility
  • Mechanical galvanizing meets ASTM B695, Class 65, Type 1, intended for some pressure-treated wood sill plate applications; not for use in other corrosive or outdoor environments
  • Size: 3/8 in. x 4-in
  • Caution: Use a Titen HD screw anchor one time only — installing the anchor multiple times may result in excessive thread wear and reduce load capacity

Can these be used to fasten a vertical wood post to a brick wall?

Asked by Randy August 17, 2020
1
Answer

The Titen HD is rated for attachment to concrete or CMU, but it is not rated for attachment to red brick. Thank you!

Are these self-tapping, or Do you need to drill a pilot hole, and if so with what diameter bit?

Asked by eric July 9, 2020
2
Answers

Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed (1/2" for the THD50400H). Drill the hole to the specified embedment depth plus minimum hole depth overdrill (1/2" minimum hole depth overdrill for the 1/2" Titen HD) to allow the thread tapping dust to settle, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling and tapping. Thank you!

Asked by Roger June 16, 2020

Answer

The hole for the Titen HD needs to be drilled to the specified embedment depth plus minimum hole depth overdrill (1/2" for the 1/2" Titen HD anchors) to allow the thread tapping dust to settle. The anchor needs to be tightened into the base material until the hex-washer head contacts the fixture. Based on these requirements and the condition described above, a shorter Titen HD is needed. Thank you!

Is there a limit to the amount of times they can be removed and reinstalled?

Asked by Kit January 12, 2020
1
Answer

The Titen HD is removable and ideal for temporary anchoring or applications where fixtures may need to be moved, but reuse of the anchor to achieve listed load values is not recommended. Thank you!

How closely can these be installed to the edge of the concrete (e.g. near a basement window)?

Asked by Lucky November 27, 2018

Answer

The minimum edge distance for the 1/2" Titen HD anchors is 1 3/4". Thank you!

Updated installation instructions say to drill a 5/8" hole for te 1/2" diameter TITEN screw. If in doubt, CALL SIMPSON FIRST.

Asked by KWM June 5, 2018

Answers

Simpson answer says 1/2" bit/hole for a 1/2" Titen, but the technical spec's, say 5/8" (0.625) hole for the 1/2" Titen. I think Simpson is right, but ALL of the technical spec's for ALL of the Titen bolts lists 1/8" (0.125) larger. This information mistake by HD/Simpson could *really* screw a lot of people up by having them drill a hole that is too large--leading to catastrophic failures.

Are these Grade 5 rated

Answer

Please refer to ESR-2713 (found on our website: strongtie.com) for mechanical properties of this anchor. Thank you!

Can this screw anchor be drilled into new concrete with a regular 1/2 inch drill?

Asked by Gdaddy March 21, 2017
2
Answers

Yes! I installed 15 of these in new concrete and they worked great. Using the hammer drill feature on your 1/2 in. drill will drill the holes twice as fast. Also be sure to blow the concrete dust out of the holes before installing the bolts. I used a soft drink straw--if you don't have an air compressor.

These are theoretically faster to install and with a lower profile than wedge anchors. A huge plus about them is you can uninstall them quite easily, something that cannot be said for wedge or epoxy installations. They can also be installed to code without a washer. I recommend you have a powerful impact wrench to install them as they occasionally become nearly impossible to drive otherwise when within 1 inch of maximum depth. Only use the zinc-plated where corrosion is not of great concern, otherwise spend extra for galvanized.

This anchor bolt is all that I expected. Hefty. Strong. It really grips the concrete. You can remove them or leave them in without reaming out the hole rendering it unusable. I use them to attach deck ledger boards to concrete. I will always use this product on my projects.

These were used to fasten the Simpson UFP10-SDS3 foundation plate to the concrete foundation wall. We used a cordless 1/2" Milwaukee impact drill to install these, and it was a easy-peasy. Nice, tight grip, and installed very quickly. Make sure you vacuum out holes before installing, makes all the difference in the world.
