Product Details

The Marine Fasteners RP-54 is a 100-piece pack of 1/4"-20 x 3/4" hex cap screws engineered for use in demanding marine environments. With a coarse UNC thread pitch of 20 threads per inch and a 3/4-inch length measured from under the head to the tip, these fasteners are sized for a wide range of boat building, repair, and maintenance applications.

Key Features:

  • Size: 1/4"-20 x 3/4" — coarse thread, fully threaded shank
  • Quantity: 100 pieces per pack — ideal for production use and bulk jobs
  • Head Style: Hex cap (six-sided) — accepts standard hex wrench or socket for high-torque installation
  • Thread Standard: UNC (Unified National Coarse) — compatible with standard 1/4"-20 nuts, inserts, and threaded holes
  • Marine-Grade Construction: Designed to resist the corrosive effects of saltwater, humidity, and marine atmosphere
  • Broad Application: Suitable for deck hardware, hatches, cleats, brackets, panels, and general onboard fastening tasks

Hex cap screws feature a smooth shank body with a threaded end, and are typically paired with flat washers and a hex nut for a secure, load-distributing assembly. The six-sided head allows precise torque application, making them well-suited for structural and mechanical connections found throughout a vessel. Sold in a convenient 100-piece pack, the RP-54 is a practical bulk-supply choice for boatbuilders, marine technicians, and serious do-it-yourself boat owners.

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

Have not had time to install, I will let you know how it turns out. Thanks

I found the product I wanted, and the order was easy to complete. All info was clear and precise, so did not have to speak with anyone! Acknowledgement of the order was prompt and was filled and shipped almost immediately. Packaged well and received within a few days. I certainly will consider the seller should the time arise in the future.

Great job

Excellent customer service, fast shipping and good quality products. Thank you Boatplicity Team

So far, so good!
