Simpson 7/16 inch Plywood Sheathing Clips by Simpson Strong-Tie are designed to brace unsupported sheathing edges where adjacent plywood panels meet edge to edge without a rafter beneath for support. These lightweight roof sheathing clips are stamped from 20-gauge steel and finished with a zinc galvanized G90 coating, providing reliable corrosion resistance for roofing applications. By spanning the gap between panel edges, they reduce deflection, keep panels flush, and maintain a level plane across the roof deck - making them an essential component in standard plywood and OSB roof sheathing installations.

Key Features

• Designed for 7/16 inch panel thickness - matches directly to standard 7/16 in. plywood and OSB sheathing for a secure, flush fit without modification
• Provides a built-in 1/8 inch gap between adjacent panels - accommodates natural shrinkage and expansion of roof sheathing, reducing the risk of buckling or warping over time
• Reduces deflection at unsupported panel edges - keeps adjoining sheathing panels even and aligned, maintaining a smooth, level surface across the roof structure
• 20-gauge steel construction - delivers reliable structural performance while remaining lightweight and easy to handle and insert during installation
• Zinc galvanized G90 coating - resists corrosion in outdoor roofing environments where moisture and humidity are constant factors
• Made in the United States - manufactured to consistent quality standards for dependable performance on residential and light commercial roofing projects

Why This Product

• Solves the unsupported edge problem - when sheathing panels meet without a rafter beneath, these clips provide the bracing needed to prevent edge deflection and panel misalignment, a common issue on standard rafter spacing layouts
• The 1/8 inch built-in expansion gap is engineered directly into the clip design, eliminating guesswork during installation and helping panels respond naturally to seasonal moisture changes without damage
• G90 zinc galvanized finish means these clips hold up in outdoor roofing conditions where uncoated steel would degrade, supporting long-term performance of the roof sheathing assembly
• Lightweight 20-gauge profile makes installation fast and practical - simply insert over the edges of adjacent plywood panels without special tools, keeping the work moving on the roof deck

Frequently Asked Questions

What panel thickness are these sheathing clips designed for?

These clips are sized specifically for 7/16 inch plywood or OSB sheathing panels. It is important to match the clip size to the actual panel thickness for proper fit and performance.

Why do these clips have a 1/8 inch gap built in?

The 1/8 inch gap is intentionally designed into the clip to address the natural shrinkage and expansion that occurs in roof sheathing panels over time. This spacing helps prevent buckling or panel distortion caused by moisture-related movement in the wood.

Where exactly are plywood sheathing clips installed on a roof?

Sheathing clips are inserted over the edges of adjacent plywood panels at locations where two panel edges meet without a rafter or other framing member beneath for support. They are placed along the unsupported edges between rafters to brace those edges and reduce deflection.

What is the coating on these clips and why does it matter?

These clips carry a zinc galvanized G90 coating, which provides corrosion resistance suited to outdoor roofing applications where panels are exposed to moisture during and after installation. The G90 designation refers to the weight of zinc coating applied, indicating a durable galvanized finish.
