Product Details

Marine Fasteners RP-780 flat head machine screws are fully threaded 1/4-20 x 1-1/2-inch fasteners designed for marine and saltwater environments. Sold in a convenient 50-piece pack, these screws deliver reliable, corrosion-resistant performance for deck hardware, cabin fittings, and other onboard fastening applications.

Key Features:

  • Size: 1/4-20 thread x 1-1/2 inch length
  • Head Style: Flat (countersunk) — sits flush with the surface for a clean, finished appearance
  • Thread Type: UNC (Unified National Coarse) — 20 threads per inch
  • Fully threaded shank for consistent, secure fastening into pre-tapped holes or with a nut
  • Marine-grade corrosion resistance — suitable for wet, saltwater, and high-humidity environments
  • Pack Quantity: 50 pieces per pack

These machine screws are ideal for securing cleats, hinges, hatches, trim panels, and other hardware on boats, PWCs, and marine equipment. The flat countersunk head design allows for flush mounting where a smooth surface profile is required.

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.
