The Ace #15 FATnSTRONG™ Roofing Fasteners are designed to be used with Ace Screws Insulation and Membrane Plates to secure ridged insulation, base sheet, EPDM, TPO, PVC, to steel or wood structural decks. Fasteners ranging in length from 1-1/4” to 24” are available to meet a variety of commercial roofing applications.

Method of Application

1. Using the #3 Phillips tip provided, and a variable speed drill, engage the fastener into the deck as noted below. Do not over or under drive the fastener. Threads must engage the decking material per Technical Specifications.

2. Determine screw length as follows:

a. Steel Decks: Select fastener length to penetrate through the deck a minimum of 3 ⁄ 4" (19.1 mm).

b. Wood Decks: Select fastener length to penetrate into or through the deck a minimum of 1" (25.4 mm).

3. Ace #15 Fasteners may not work as expected through existing roof systems or unusual substrates.

4. For best results, use a variable-speed screw gun (0-2500 RPM). Do not over tighten.


Store in original, unopened packaging protected from the weather.


Eye protection must be worn during the installation of the fasteners.
