Simpson Strong-tie HTP37Z Heavy Tie Plate 3x7 in Galvanized

Product Description

The SIMPSON STRONG-TIE HTP37Z is a nail-on heavy tie plate engineered to reinforce wood-to-wood connections on flat structural members. Fabricated from 16-gauge galvanized Z-Max steel, this plate delivers corrosion resistance suited to treated lumber applications and protected interior framing. It measures 3 inches wide by 7 inches long and installs using 20 ten-penny by 1-1/2-inch fasteners. Carpenters, framers, and general contractors reach for this plate during structural repair, retrofit, and new-construction framing tasks where flat-member connections require added rigidity and load transfer.

This tie plate is commonly used in residential home repair and light construction projects. It is applied to flat wood members where a simple, mechanically fastened connection needs reinforcement — such as spliced joists, doubled plates, or beam repairs. The nail-on installation method requires no special tools beyond a hammer or nail gun, making it straightforward for jobsite use. The Z-Max galvanized coating makes it compatible with ACQ and other treated lumber types commonly found in repair and renovation work.

Installation Notes

Installation is typically performed by framers, carpenters, or qualified general contractors. Center the plate over the joint or connection point and fasten with the specified ten-penny fasteners, ensuring full fastener count for rated load transfer. Follow applicable building code requirements, including IBC and IRC provisions for structural connector fastening. Do not substitute fastener size or count, as full nail schedule is required to achieve the intended connection capacity.
