#10 x 1" Simpson Strong-Tie Phillips Flat Head Marine Screws - 316 Stainless Steel, Pkg. 1,000

Simpson Strong-Tie Marine Flat Head Screws are designed to fasten securely into fiberglass, plywood, and other wood-substitute materials. Built to perform in harsh marine and chemically caustic environments with maximum corrosion resistance, these screws deliver strength and reliability where other fasteners fail. The flat head design ensures a smooth, flush surface finish, making them ideal for demanding applications above or below the waterline. With a high-low thread form with engineered teeth to cut through dense materials quickly, these screws drive easily and hold tight. An extra-sharp point speed starts during assembly, while lengths up to 1" are fully threaded and longer sizes feature partial threading for greater pull-through strength. A #2 Phillips drive makes installation straightforward with widely available driver bits.
