Product Details

The Seachoice RP-SC30075 is a premium marine-grade hex cap screw designed for superior corrosion resistance in harsh saltwater environments. Constructed from 316 stainless steel, this fastener offers exceptional durability and longevity in marine applications where standard fasteners would quickly corrode.

Key Specifications:

  • Thread Size: 5/16"-18 (coarse thread)
  • Length: 3/4 inch
  • Material: 316 stainless steel (marine-grade)
  • Head Style: Hex cap (external hex drive)
  • Package Quantity: 25 pieces per bag

Features & Benefits:

  • 316 stainless steel construction provides superior corrosion resistance compared to 304 stainless steel
  • Hex head design allows for high-torque application with standard wrenches or sockets
  • Ideal for boat hardware, deck fittings, marine equipment, and underwater applications
  • Resists pitting and crevice corrosion in saltwater environments
  • Convenient 25-piece packaging for multiple repairs or installations

These hex cap screws are essential fasteners for boat owners, marine contractors, and anyone working on saltwater-exposed equipment where reliability and corrosion resistance are critical.

Great! Equal to any

This was one of the few places I could find that had these in stock.

Great service! Gave additional first responder discount

Incredibly easy to find the part and price is great.

Found the best price for the tires I needed here. Mixed production years but can't complain for the price. Arrived very quickly.

Awesome all around

Right part. Fast delivery. No issues at all.

FedEx shipping was iffy but that's not your fault. Assembly instructions or at least an exploded diagram of all the piece parts of the cover kit would have been helpful.
