Frequently Asked Questions

What type of fasteners should be used to install the MTS30Z?

Install with 10d common nails or 10d x 1-1/2 in. nails.

What is the purpose of the 2" bend section on the MTS30Z?

The 2" bend section eliminates interference at the transition points between wood members, allowing for a cleaner and more secure connection without obstruction.

Why is ZMAX galvanization important for this twist strap?

ZMAX galvanization offers extra corrosion resistance, making the MTS30Z suitable for exterior applications and use with treated wood, where standard coatings may not provide adequate protection against moisture and chemical exposure.

Does the strap need to be wrapped over the truss to achieve its allowable load rating?

No. The MTS30Z does not need to be wrapped over the truss to achieve the allowable load, simplifying installation while still delivering reliable performance.
