Simpson Strong-tie TP37 Nail-on Tie Plate

Product Description

The SIMPSON STRONG-TIE TP37 is a nail-on tie plate designed to reinforce wood-to-wood connections on flat framing members. Stamped from 20-gauge galvanized steel, it provides corrosion resistance for both interior and exterior repair applications. Nail holes are sized to accept 8d common or 8d x 1-1/2 nails, making fastener selection straightforward. Carpenters, framers, and general contractors reach for this plate when a flat connection needs mechanical reinforcement without specialty hardware. Its simple flat profile keeps the installation low-profile against the lumber face.

The TP37 tie plate is commonly used in residential repair and light construction projects where wood members meet flat and need additional load transfer. Typical applications include reinforcing spliced joists, repairing cracked or split lumber, and strengthening flat wood-to-wood connections in floor systems, wall framing, and roof framing. It is well suited for home repair work where a straightforward mechanical fastener solution is needed on accessible framing members.
