Cold-Formed Steel: LTS/MTS/HTS Twist Straps

(MTS and HTS
similar)

MTS30 (HTS30 similar)

MTS30C (HTS30C similar)

Twist straps provide a tension connection between two members. They resist uplift at the heel of a truss economically. The 3" bend section eliminates interference at the transition points between steel members.

Material: See table.

Finish: Galvanized. Some products available in stainless steel and ZMAX®; see Corrosion Resistance.

Installation: Use all specified fasteners. See General Notes.

Not all fastener holes need to be filled as additional fastener holes are provided. Install fasteners symmetrically.
Install half of the fasteners on each end of strap to achieve full loads.
Tabulated loads are governed by tests and may not be increased. Refer to Steel Stress Increase for additional information.
All straps except the MTS30 and HTS30 have the twist in the center of the strap.
Twist straps do not have to be wrapped over the truss to achieve the load.
May be installed on the inside face of the stud.
Loads are based on steel with 43 mil (18 ga) minimum.
