CORROSION RESISTANT FASTENERS OF ALL TYPES
Bronze, or silicon bronze, has superior corrosion resistance to stainless steel and has a high strength. Silicon bronze is used less often due to its high cost.
Brass is highly corrosion resistant and electrically conductive. Because it is relatively soft, brass is typically used in applications where appearance is more important than strength.
ALUMINUM (PLAIN & 205 ALUMILITE FINISH)
Aluminum is light and soft with good corrosion resistance. Aluminum fasteners can be made from a variety of alloys to increase strength and melting point.
STAINLESS STEEL (304 & 316)
Stainless steel is highly corrosion resistant yet less expensive than bronze, brass, or aluminum which makes it an attractive choice. However, stainless steel fasteners are only slightly stronger than unharded Grade 2 steel fasteners. Type 304 Stainless is the most common and least expense, but Type 316 offers better corrosion resistance. We have developed a proprietary chrome formula called Eagle Shield™ we apply over 18-8 stainless steel. Click the link below for details.
Galling, or seizing up during applicaiton, is a known issue with stainless steel fasteners. As a solution, we recommend using stainless steel bolts with silicon bronze nuts. Our customers have reported great success in the field with this combination.
