The Simpson PSCA 7/16-in. 20-Gauge Galvanized Panel Sheathing Clip is engineered by Simpson to brace unsupported sheathing edges where plywood panels meet edge to edge without a rafter for support. Inserted over the edges of adjacent 7/16-in. plywood panels, this light roof sheathing clip reduces deflection and keeps panels even to maintain a level plane on the structure, while providing the recommended 1/8-in. gap to accommodate the natural shrinkage and expansion of roof sheathing over time.

Key Features

• Designed for 7/16-in. panel thickness - ensures a precise, secure fit on compatible plywood panels without guesswork or modification.
• No nails required for installation - clips slip directly over panel edges for fast, tool-free installation that keeps roofing projects moving efficiently.
• Provides the APA-recommended 1/8-in. gap between panels - automatically spaces adjacent plywood panels to the correct clearance, helping prevent buckling caused by seasonal wood movement.
• Supports natural shrinkage and expansion over time - built-in spacing accommodates the long-term dimensional changes common in roof sheathing, protecting the structural integrity of the installation.
• Made from 20-gauge steel - delivers reliable rigidity and holding strength to reduce panel deflection and maintain a flat, even roof plane.
• G90 zinc galvanized coating - provides corrosion resistance suited to roofing environments where moisture exposure is a concern, helping extend the service life of the clips.
• Sold in a 250-count package - bulk quantity covers large roof sheathing projects without the need for multiple separate purchases.

Why This Product

• Maintains a level roof plane without extra hardware - by reducing deflection at unsupported panel edges, these clips help ensure a flat, even surface for roofing materials, minimizing the risk of visible waves or weak points in the finished roof deck.
• Built-in spacing eliminates a common installation error - the clip automatically provides the 1/8-in. gap recommended by the American Plywood Association, so installers do not need to measure or estimate panel spacing manually on every course.
• Fast, nail-free application saves labor time - because the PSCA clips require no fasteners or special tools, they can be placed quickly between panels during sheathing installation, helping crews maintain a steady work pace across large roof areas.
• Corrosion-resistant construction supports long-term performance - the G90 galvanized finish on 20-gauge steel means these plywood panel clips are built to hold up in the demanding conditions of a roof assembly, reducing concerns about premature deterioration.

Frequently Asked Questions

What size panels are these sheathing clips designed for?

These clips are specifically designed for 7/16-in. panel thickness. As a general rule, you should use the same size sheathing clip as the panel thickness you are working with.

Do the PSCA sheathing clips require nails or special tools for installation?

No. The PSCA sheathing clips are designed for quick installation with no nails required. They are simply inserted over the edges of adjacent plywood panels during installation.

Why is the 1/8-in. gap important, and who recommends it?

The 1/8-in. gap provided by the PSCA clip is important because it allows roof sheathing to naturally shrink and expand over time without causing structural issues. This spacing is recommended by the American Plywood Association to help maintain the integrity of the roof sheathing installation.

What corrosion protection do these sheathing clips offer?

The PSCA sheathing clips are made from 20-gauge steel with a G90 zinc galvanized coating, which provides reliable corrosion resistance to help ensure long-term performance in roofing applications.
