ANSI B18.5 rated

Type 316 Stainless Steel Carriage Screws-

Better corrosion resistance than Type 304. Low carbon chromium-nickel stainless with good weldability and temperature resistance. Max. temp. to maintain corrosion resistance is 1600 degrees F.
This austenitic stainless steel has an increased molybdenum content to increase its resistance to corrosion when compared to other 300 series alloys.
316 is recommended for any application exposed to saltwater (including immersion).

Silicon Bronze Carriage Screws- Nonmagnetic, corrosion resistance from salt water. B85 Rockwell hardness. 70K PSI Tensile strength.

18-8 Stainless Steel Carriage Screws- Corrosion-resistant, slightly magnetic. .

Grade 5 Zinc-Plated Steel Carriage Screws- Rust Resistant. SAE J429. C25 Rockwell. 120K PSI Tensile strength.

Grade 2 Zinc-Plated Steel Carriage Screws- Full Threads. Made of Grade 2 zinc-plated steel. B80 Rockwell, . 75k PSI Tensile strength.

Grade 2 Hot-Dipped Galvanized Steel Carriage Screws-
