Frequently Asked Questions

What is the purpose of the Simpson SPH4Z stud plate tie?

The SPH4Z is a heavy U-shaped strap designed as a stud-to-plate connection to resist roof uplift. Its horizontal portion bears against wood wall top plates or sill plates, while two vertical legs are nailed to the edges of a wood stud to create a secure, uplift-resistant connection.

What type of galvanization does the SPH4Z have, and why does it matter?

The SPH4Z features ZMAX galvanization, which offers extra corrosion resistance compared to standard galvanized coatings. This makes it suitable for exterior applications and use with treated wood, where exposure to moisture or chemicals could degrade a lesser finish over time.

What fasteners are required to install the SPH4Z?

Installation requires 10 to 12 nails measuring 0.148 in. x 1-1/2 in. For best results, the tie should be installed before the placement of the wall.

Does the SPH4Z require top or bottom track attachment?

No. The SPH4Z does not require top or bottom track attachment, simplifying installation and making it a cost-effective stud-to-plate connection option for resisting wind and seismic forces.
