The Seachoice RP-SC3815 is a heavy-duty carriage bolt designed for marine and outdoor applications where corrosion resistance is essential. This fastener features a 1/2"-13 thread size with a 4-inch length, making it ideal for securing dock hardware, boat trailers, outdoor decking, and marine structures.

Key Features:

• Hot-dipped galvanized steel construction provides superior corrosion resistance in saltwater and harsh outdoor environments
• 1/2"-13 thread diameter with 4-inch length for secure fastening of thick materials
• Carriage bolt design with smooth rounded head and square neck prevents spinning during installation
• Sold in convenient 25-piece pack for multiple projects
• Meets marine-grade standards for reliability in demanding conditions

Carriage bolts are characterized by their domed head and square shoulder beneath the head, which pulls into the material to prevent rotation when tightening the nut. The hot-dipped galvanizing process provides a thick protective zinc coating that significantly extends the service life of these fasteners in marine environments, making them an excellent choice for boat owners, dock builders, and marine contractors.
