Marine Fasteners RP-583 #8 x 1/2in Phillips Oval Head Self-Tapping Screws 100-Pack

The Marine Fasteners RP-583 is a 100-piece pack of #8 x 1/2-inch Phillips oval head self-tapping screws crafted from 18-8 stainless steel for reliable corrosion resistance in marine and outdoor environments. These versatile sheet metal screws are ideal for securing hardware, trim, and accessories to fiberglass, thin sheet metal, and wood — common tasks aboard boats and in coastal applications.

Key Features:

• Size: #8 x 1/2 inch
• Drive Type: Phillips (cross-head)
• Head Style: Oval — similar to a flat head but with a slightly domed top for a more finished, decorative appearance
• Thread Type: Self-tapping (Type A coarse thread) — taps its own mating threads during installation
• Material: 18-8 Stainless Steel — resistant to rust, salt spray, and corrosion
• Quantity: 100 pieces per pack
• Versatile Use: Suitable for fiberglass, wood, and sheet metal applications

The oval head profile provides a clean, countersunk-style appearance with a slightly raised dome, making these screws a popular choice for visible installations where aesthetics matter. The Phillips drive allows for efficient installation with standard Phillips screwdrivers or power tools. Sold in a convenient 100-piece pack, the RP-583 is well-suited for both on-board repairs and boatyard projects.
