Product Details

The Seachoice RP-SC30083 is a premium marine-grade hex head cap screw designed for demanding saltwater and freshwater applications. Manufactured from 316 stainless steel, this fastener delivers superior corrosion resistance in harsh marine environments where standard fasteners would quickly deteriorate.

Key Specifications:

  • Thread Size: 5/16"-18 (5/16 inch diameter, 18 threads per inch)
  • Length: 2-1/2 inches
  • Material: 316 marine-grade stainless steel
  • Head Style: Hex cap (external hex drive)
  • Package Quantity: 10 pieces per bag

Benefits:

  • 316 stainless steel construction provides maximum resistance to saltwater corrosion and pitting
  • Hex head design allows for high-torque applications and easy installation with standard wrenches or sockets
  • Ideal for through-bolting applications on boats, docks, trailers, and marine equipment
  • Fully threaded shaft ensures secure fastening in a variety of mounting configurations

This fastener is an essential component for boat repairs, marine hardware installation, and trailer maintenance where reliability and corrosion resistance are critical. The 316 stainless steel alloy contains molybdenum, which significantly enhances its resistance to chloride environments compared to 304 stainless steel.

The only thing that didn't go very well was the time it took to receive the 2nd part of my order. I paid extra for 2 day shipping. It took closer to 6 days to receive my CDI switch box.

Great if I order again I will be using the same website again. Thanks

Happy, just didn't get confirmation email after order was placed.

Overall I had a good experience.

It was good

Quick easy service!

Was easy to order online
