Marine Fasteners RP-642 #10 x 3" Phillips Flat Head Self-Tapping Screws 50-Pack

The Marine Fasteners RP-642 is a pack of 50 #10 x 3" Phillips flat head self-tapping screws engineered for marine and coastal environments. These screws are designed to cut their own threads as they drive into wood, fiberglass, and other common boat-building materials — no pre-tapping required.

Key Features:

• Size: #10 x 3" — a versatile size suited for securing panels, trim, hardware, and structural components aboard boats and marine vessels
• Drive Type: Phillips (cross-recess) head for positive bit engagement and efficient installation
• Head Style: Flat (countersunk) head for a flush, low-profile finish on fiberglass, wood, and composite surfaces
• Self-Tapping Design: Sharp tip threads into material without a pilot tap, saving installation time
• Marine-Grade Construction: Built to resist corrosion in saltwater and high-humidity environments
• Quantity: 50 screws per pack — ideal for bulk project use, repairs, and onboard spare supplies

These flat head self-tapping screws are a staple fastener for boat builders, riggers, and marine DIY enthusiasts. The countersunk flat head sits flush with the surface for a clean finish on decks, cabinetry, and hardware installations.
