Simpson Strong-Tie Marine Pan-Head Screws are built to fasten securely in fiberglass, plywood, and wood-substitute materials used in harsh marine or chemically caustic environments. The low-profile pan head helps distribute load and sits neatly on the surface, delivering a clean, professional look on boats, docks, and corrosive-area fixtures.
Engineered for tough substrates, these screws use a high-low thread with cutting “teeth” that provide a fast penetration in dense materials. Driving is straightforward with 2 Phillips.
Key Features:
- Pan Head – Low-profile, wide bearing for a clean seat
- High-Low Thread with Teeth – Cuts quickly through dense composites
- Extra-Sharp Point – Speeds starts and reduces walking
- Threading by Length – Full thread ≤ 1″, 2/3 shank thread on longer sizes
- 2 Phillips Drive – for universal compatibility on a jobsite
