Carlisle SynTec HD 14-10 1-1/4 in. Concrete Roof Fastener, Heavy-Duty Threaded Screw, 1,000-Carton
The Carlisle SynTec HD 14-10 Fastener in 1-1/4 in. length is a heavy-duty threaded concrete screw for attaching membranes, plates, and Pressure-Sensitive RUSS strips directly into structural concrete roof decks of at least 2,500 psi. Each carton contains 1,000 fasteners.
Key Features:
- Short-length option: The 1-1/4 in. length suits direct-to-deck attachment with minimal insulation build-up.
- Heavy-duty wire: Manufactured with heavy-duty #14 wire for strength and durability.
- Superior pullout: Threaded design provides outstanding pullout resistance in structural concrete.
- Corrosion resistant: Excellent corrosion resistance, surpassing the FM 4470 corrosion test.
- Reversible design: Can be reversed out of a pre-drilled hole without damage to the deck.
- FM and Miami-Dade: FM Approved and Miami-Dade County Approved.

Fit and Compatibility:
Designed for use with various Carlisle fastening plates to attach Carlisle mechanically fastened membranes and Pressure-Sensitive RUSS strips into structural concrete (minimum 2,500 psi). Note that the manufacturer PDS table lists standard sizes from 2 in. to 20 in., so confirm suitability of the 1-1/4 in. length with Carlisle Technical Services before ordering. If fastener breakage is persistent in high-strength concrete, Carlisle recommends its CD-10 Fastener.
Frequently Asked Questions (FAQ):
Q: What is included in the carton?
A: One carton contains 1,000 of the 1-1/4 in. HD 14-10 concrete fasteners; fastening plates are sold separately.
Q: What drill bit do I need?
A: Drill with an ANSI standard 3/16 in. (5 mm) bit; a 7/32 in. (5.6 mm) bit may be substituted if fastener breakage is encountered, provided pullout resistance is not compromised.
Q: When should I use the 1-1/4 in. length?
A: Use it for short fastening applications such as securing RUSS strips or direct-to-deck attachment where only the 1 in. minimum embedment is needed.
Q: What decks does this fastener work in?
A: It is designed for structural concrete roof decks with a minimum compressive strength of 2,500 psi.
Q: What if fasteners twist off during installation?
A: High-strength concrete decks can cause threaded fasteners to break; Carlisle recommends its CD-10 Fastener if breakage is persistent.
Q: Are these fasteners corrosion resistant?
A: Yes, the HD 14-10 has excellent corrosion resistance, surpassing the FM 4470 corrosion test.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Keep the minimum 1 in. embedment in mind with this short length: after plate and material thickness, there is little extra thread in the concrete, so verify pullout resistance for your assembly. Pre-drill with the 3/16 in. ANSI bit and tighten with a screw gun. For thicker insulation stacks, step up to a longer HD 14-10 size.
Eye protection is recommended during drilling and installation of fasteners; review Carlisle specifications and details for complete installation information.
