Cold-Formed Steel: S/LTT & S/HTT Tension Ties

The S/HTT14 is a single-piece formed tension tie - no rivets, and a 4-ply formed seat which won't unfold during loading. No washers are required.

The S/LTT and S/HTT Tension Ties are ideal for retrofit or new construction projects. They provide high strength, post-pour, concrete-to-steel connections.

Material: See table.

Finish: Galvanized.

Installation:

Use all specified fasteners.
Use the specified number and type of screws to attach the strap portion to the steel stud. Bolt the base to the wall or foundation with a suitable anchor; see table for the required bolt diameter.
Do not install S/LTT20 raised off of the bottom track.
Refer to Anchor Designer Software™ for ACI 318 for anchoring solutions.

S/LTT20	S/HTT14 U.S. Patent 5,467,570	Typical S/HTT14 Installation as a Holdown
	UPDATE SEPT. 2009: S/HTT14 is now being manufactured with different tooling. This has caused some minor dimensional changes in the part. The images above have been updated to reflect these changes, as have the DWG and DXF drawings below.

The Designer shall specify the anchor embedment and configuration. See SSTB Anchor Bolts.
Tabulated loads shown at (100) do not include steel stress increase. Tabulated loads shown at (133) include a 1/3 stress increase on the steel. Refer to Steel Stress Increase for additional information.
Back-to-back stud members are required unless otherwise specified. The design of the studs is the responsibility of the building designer.
The allowable tension load of the S/HTT14 is 2475 lbs. when connected to a single 33 mil (20 ga.) stud.
S/LTT and S/HTT allowable tension loads at 1/8" deflection are 1200 lb and 3715 lb respectively.
See S/HDU notes regarding deflection at highest allowable design load.
