Marine Fasteners RP-858 Oval Head Machine Screw 1/4-20 x 2-1/2in Stainless Steel 25-Pack

The Marine Fasteners RP-858 is a pack of 25 oval head machine screws in a 1/4-20 x 2-1/2 inch configuration, purpose-built for marine and saltwater environments. Oval head machine screws offer a low-profile, finished appearance with a slightly domed top and a countersunk bearing surface, making them ideal for applications where both function and aesthetics matter.

Manufactured to withstand the harsh conditions of marine use, these fasteners resist corrosion from saltwater, humidity, and UV exposure. The 1/4-20 thread pattern (1/4-inch diameter, 20 threads per inch — UNC coarse thread) provides reliable holding strength across a wide range of marine hardware applications including deck fittings, hatches, trim panels, and accessory mounting.

Key Features:

• Oval (countersunk with dome) head style for a clean, finished look
• Thread size: 1/4-20 UNC (coarse thread)
• Length: 2-1/2 inches
• Quantity: 25 pieces per pack
• Designed for marine-grade corrosion resistance
• Suitable for use with standard 1/4-20 nuts and threaded inserts

Packaged in a convenient 25-piece quantity, the RP-858 is well-suited for both professional marine technicians and do-it-yourself boaters looking for reliable, marine-rated fasteners in bulk.
