Product Details

The Marine Fasteners RP-780 is a pack of 50 flat head machine screws sized 1/4-20 x 1-1/2 inches, engineered for reliable performance in demanding marine environments. With a fully threaded shank and a low-profile countersunk flat head, these machine screws are designed to sit flush with the surface for clean, snag-free installations on boats, docks, and other marine applications.

Key Features:

  • Size: 1/4-20 thread pitch x 1-1/2 inch length
  • Head Style: Flat (countersunk) for flush-mount installations
  • Thread Type: Unified Coarse (UNC) machine screw thread — designed to engage a nut or pre-tapped hole
  • Pack Quantity: 50 pieces per pack
  • Application: Ideal for through-bolting hardware, securing deck fittings, mounting brackets, and general marine fastening tasks
  • Marine-Grade Construction: Built to resist the corrosive effects of salt air, moisture, and UV exposure

Machine screws with a 1/4-20 thread are one of the most commonly used fastener sizes in marine hardware installations, making the RP-780 a practical bulk pack to keep on board or in the shop. The flat head profile allows the screw to countersink flush into the material surface, providing a smooth, professional finish on fiberglass, metal, and composite surfaces.

Great product

Customer service was nice and kind, still waiting on my return for my second product I purchased. The first purchase was perfect.

Tires in the add show studded tires but what I received was studdless tires . Will talk to THM Motorsport after this. But price was great

Very quick turnaround with best online price. Would highly recommend!

Fast service!!

It was what I needed, and worked perfectly, great price

Very easy to find and choose my tires and the shipping was fast

I have one of these on another boat. I love it and it's saved my lower unit more than once when I unexpectedly found a stump or hard bottom.. It also allows me to run with the motor higher because if the set back.
