What Bolts and Screws Should I Use for Fiberglass Boats?

Fiberglass boats require fasteners that provide:

• Strength to handle the structural demands.
• Corrosion resistance to withstand exposure to moisture and salt. We recommend stainless steel fasteners (304 or 316 grades):
• 316 stainless bolts: Ideal for marine applications, offering superior resistance to rust and chemical exposure.
• Brass screws and bolts: While less common than stainless steel, brass can be an alternative for low-stress areas because of its good corrosion resistance.

Avoid galvanized fasteners, as they are prone to rust and corrosion when exposed to saltwater environments.
