Product Details

The Marine Fasteners RP-79 is a pack of 25 5/16-18 x 1-1/2 inch hex cap screws engineered for reliable performance in demanding marine environments. These fasteners feature a standard UNC (Unified National Coarse) thread pattern and a full hex head for easy installation and removal with standard wrenches or sockets.

Key Features:

  • Size: 5/16-18 x 1-1/2 in (5/16" diameter, 18 TPI coarse thread, 1-1/2" length)
  • Thread Type: UNC (Unified National Coarse) — 18 threads per inch
  • Head Style: Hex cap (full hex head for wrench or socket drive)
  • Quantity: 25 pieces per pack
  • Application: Designed for marine use — resistant to corrosion from saltwater, moisture, and UV exposure
  • Material: Stainless steel construction for superior corrosion resistance

Sold in a convenient 25-piece pack, the Marine Fasteners RP-79 is ideal for boat building, repair, and maintenance applications where standard hardware-grade fasteners would corrode prematurely. These hex cap screws meet the demands of both freshwater and saltwater environments.

Easy purchase and searching

Paid for 2-day shipping but it took 4 days. I have not used the Simrad GPS yet so I cannot comment.

Easy to find the product and easy to order. Shipping took a little longer than anticipated but overall, it was a good experience
