Simpson Strong Tie HTP37Z Heavy Tie Plate 16 Gauge Zmax

Product Description

The SIMPSON STRONG TIE HTP37Z is a heavy tie plate designed to reinforce structural lumber connections in wood-frame construction. Measuring 3 inches by 7 inches and formed from 16-gauge steel, it delivers the load-transfer performance framing and decking applications demand. The Zmax coating provides enhanced corrosion resistance, making this plate suitable for exterior and treated-lumber environments where standard galvanized finishes may fall short. Licensed contractors, framers, and structural carpenters install this plate to strengthen butt joints, splice points, and general lumber-to-lumber connections where additional bearing area is required.

The HTP37Z fits residential and light commercial wood-frame applications including floor framing, wall framing, decking substructure, and roof framing. Its flat-plate profile allows it to seat flush against dimensional lumber, keeping the assembly tight without creating interference with adjacent structure. The pre-punched nail holes align with standard fastener patterns, simplifying layout and installation on the job site.

Key Features

• 3 inch by 7 inch plate footprint provides broad bearing area for load distribution
• 16-gauge steel construction delivers structural rigidity under shear and tension loads
• Zmax coating offers elevated corrosion resistance for exterior and treated-lumber contact
• Pre-punched nail holes align with standard fastener patterns for consistent installation
• Flat profile seats flush against dimensional lumber without structural interference

Compatibility

Designed as an OEM-style structural connector for use with standard dimensional lumber in residential and light commercial wood-frame construction applications.

Installation Notes

Installation is performed by licensed framers or general contractors following local building code and applicable provisions of the International Building Code. Fasten using the nail or screw type and quantity specified on the engineered drawings or manufacturer load tables for the application. Do not substitute fastener type or reduce fastener count, as doing so affects rated load capacity. Inspect the mating lumber surfaces for crown, warp, or splits before fastening to ensure full plate contact.
