Carlisle SynTec HP-X 3 in. Roofing Fastener, Black, Carton of 1,000
This is Carlisle SynTec's HP-X high-performance roofing fastener in a 3 in. length, sold as a carton of 1,000 black screws. It secures Carlisle single-ply membrane and insulation to steel or wood roof decks through approved Carlisle plates. Pair it with Carlisle HP-X plates and a clutch-drive electric screw gun.
Key Features:
- Superior pull-out: Oversized heavy shank and #15 thread diameter provide enhanced pull-out resistance.
- Drill point design: The miniature drill point penetrates decks quickly and contributes to exceptional back-out and pull-out resistance.
- Buttress threads: Deep buttress threads further increase pull-out and back-out resistance.
- Corrosion resistant: CR-10 coating delivers excellent corrosion resistance, surpassing the FM4470 corrosion test.
- No pre-drilling: Installs without pre-drilling on steel decks (20- or 22-gauge) or wood decks of minimum 15/32 in. CDX plywood.
- FM Approved: This 3 in. fastener is listed as FM Approved and meets FM4470 corrosion testing.

One carton contains 1,000 three-inch fasteners. Fastener count per roof area depends on insulation thickness, deck type, and the wind uplift design pressure; follow the fastening pattern in your Carlisle specification.
Fit and Compatibility:
Designed for Carlisle single-ply membrane and insulation assemblies and installs through approved Carlisle plates (sold separately). Use on 20- or 22-gauge steel decks or minimum 15/32 in. CDX plywood wood decks. Use a clutch-drive electric screw gun (0-2,500 rpm); a #3 Phillips bit is required for the truss head.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose fastener length from the total insulation thickness plus required deck penetration, and verify pull-out on the actual deck with a fastener pull test, since deck strength varies with moisture and condition. Drive perpendicular to the deck and into the top flutes of steel decks for optimum performance, using a clutch-adjusted screw gun to avoid overdriving. Pair with approved Carlisle HP-X plates to complete a Carlisle-system attachment that supports wind uplift ratings.
Wear eye protection during drilling and installation, and take care not to overdrive the fastener.
Order the Carlisle SynTec HP-X 3 in. fastener carton of 1,000 to secure your single-ply roofing assembly.
