Product Details

Seachoice stainless steel hex cap screws are marine-grade fasteners for boat, trailer, and general hardware use. Each hex head cap screw is a threaded bolt-style fastener. You drive it with a wrench or socket, so it can be tightened firmly and evenly.

Key Features:

  • Stainless steel construction resists rust and corrosion in wet, humid, and salt-air environments
  • Hex head design works with standard wrenches and sockets for secure tightening
  • Fully threaded cap screw style suits bolting into tapped holes or through assemblies with a nut and washer
  • Available in multiple thread sizes and lengths to match a wide range of projects

Seachoice makes hardware for the boating market, and these cap screws are built to last in harsh marine conditions. Pair them with matching stainless nuts and washers for a consistent, corrosion-resistant assembly.
