Product Details

The Marine Fasteners RP-856 is a pack of 50 oval head machine screws sized 1/4-20 x 1-1/2 inches, designed for reliable performance in marine, coastal, and general fastening applications. The oval (also known as raised countersunk) head profile sits slightly above the surface after installation, offering a finished, decorative appearance while providing a flush-friendly countersunk base.

Key Features:

  • Thread Size: 1/4-20 (1/4-inch diameter, 20 threads per inch — Unified National Coarse)
  • Length: 1-1/2 inches
  • Head Style: Oval (raised countersunk) — decorative, low-profile finish
  • Drive Type: Phillips or slotted (standard for oval machine screws)
  • Quantity: 50 pieces per pack
  • Engineered for marine-grade durability and corrosion resistance in wet and saltwater environments
  • Suitable for use with standard 82° countersunk holes

These machine screws are ideal for boat building, dock hardware, deck fittings, and general marine assembly where a clean, finished appearance is required. The 50-piece pack ensures you have plenty on hand for larger projects or ongoing maintenance.

Super grateful you had the part. I searched other location and nobody had it in stock. You saved my bacon after the freezing temps. Will definitely shop here again and very fast delivery!

Informative and helpful ordered tires and the process was smooth. Shipping company was quite slow compared to others that we've ordered from buy tires just showed up and seemed to be good. Thank you.

Good price and fairly fast shipping.

We found a tire here that was hard to find and it was shipped quickly. Great experience and would use this company again.
