Material Description
Brass An alloy of copper with good corrosion resistance. Once common for marine use brass is now used mostly in decorative applications.
Zinc plated steel Steel is zinc plated for moderate protection against rust.
Steel grade 5 Made from medium carbon steel. Used in automotive applications and where higher strength is desired.
Steel grade 8 Made from tempered medium carbon alloy steel and zinc plated. Best for applications where high strength and hardness is required.
Stainless steel 18-8 left hand These fasteners are left hand (reverse) threaded. Stainless steel 18-8 is an alloy of steel with high corrosion resistance. Stainless has become the material of choice for exterior and most marine applications.
Stainless steel 18-8 Stainless steel 18-8 is an alloy of steel with high corrosion resistance. Stainless has become the material of choice for exterior and most marine applications.
Silicon Bronze Bronze is an alloy of copper with greater strength and corrosion resistance than brass. Most commonly used in wood boat building and restoration.
Hot dipped galvanized Hot dipped galvanized fasteners are much more corrosion resistant than zinc plated fasteners. Due to the thickness of the galvanized coating, galvanized bolts will only work with galvanized nuts. For exterior and coastal area use. (ASTM A153)
Grade 2 chrome A grade 2 fastener with a bright mirror-like finish providing sharp looks for a variety of applications
