For reliable insulation attachment in low-slope commercial roofing, the Ace #12 SKINNYnSTRONG™ series, distributed by A1A Wholesale Supply, provides exceptional value without compromising on structural integrity. These screws are manufactured from heat-treated SAE 1022 steel, ensuring they have the hardness required to penetrate heavy-gauge steel decks while maintaining the tensile strength necessary to resist wind uplift.
The SKINNYnSTRONG™ design features 13 threads per inch and a specialized high-performance drill point for rapid engagement. Like its larger #15 counterpart, the #12 fastener is protected by a premium Black e-coat finish, which has been tested to withstand 15 cycles of the Kesternich DIN 50018 test with less than 15% red rust. This makes it an ideal choice for securing cover boards and rigid insulation in standard commercial assemblies where a thinner diameter fastener is specified.
Product Details
Manufacturer: Ace Screws.
Material: Heat-treated SAE 1022 Steel.
Coating: Black e-coat (Exceeds FM 4470 Requirements).
Head Style: #3 Phillips Drive.
Thread Count: 13 Threads per Inch.
Compliance: ASTM F6096/F606M-2019; DIN 50018 (Kesternich).
Length Range: 1-5/8” to 8”.
Features & Benefits
High-Speed Installation: The high-performance drill point reduces “point walking” and allows for faster penetration into steel and wood decks.
Corrosion Resistance: The Black e-coat finish ensures the fastener’s longevity within the roof assembly, far exceeding standard building code requirements.
Versatile Deck Compatibility: Engineered for superior performance in 18–22 gauge steel and 19/32″ plywood (596 lb pull-out average).
Precise Engagement: Designed for use with a #3 Phillips tip to minimize cam-out and ensure the screw is driven straight and flush.
Optimized for Insulation: Specifically tailored for securing ridged insulation and cover boards when used with 3″ Ace insulation plates.
Installation Guidelines
Drive Speed: For best results, use a variable-speed screw gun (0–2500 RPM).
Steel Decks: Select a length that allows the fastener to penetrate through the deck a minimum of 3/4″.
Wood Decks: Select a length to penetrate into or through the deck a minimum of 1″.
Safety: Eye protection must be worn during installation. Do not over-tighten, as this can damage the insulation board or strip the deck.
