Marine Fasteners RP-591 #10 x 1/2 in. Phillips Oval Head Self-Tapping Screws 100-Pack

The Marine Fasteners RP-591 is a bulk pack of 100 #10 x 1/2-inch Phillips drive, oval head self-tapping screws engineered for marine and boating fastening applications. These sheet metal-style self-tapping screws are designed to cut their own threads as they are driven in, eliminating the need for pre-tapping and speeding up assembly tasks on board.

The oval head profile sits low and finished against the surface once installed, offering a clean, semi-countersunk appearance that minimizes snag points — ideal for trim panels, hardware mounting, and interior or exterior boat fittings. The Phillips drive ensures positive bit engagement and reliable torque transfer.

Key Features:

• Size: #10 x 1/2 in. (length measured from rim of head to tip)
• Drive Type: Phillips (cross-head)
• Head Style: Oval / oval countersunk — low-profile, semi-finished appearance
