Made of Rust and Corrosion Proof 18-8 Hardened Stainless Steel. 

• 4 JL Tailgate Bolts (inner)
• 4 Countersunk Bolts (outer)
• 4 stainless neoprene bonded sealing washers to block water out
• Any bolt that is not stainless, like ours, or titanium, will rust. In some coastal areas this process might take months or even weeks. We highly recommend the use of anti-seize with all of our bolts. The use of anti-seize on the bolt threads adds additional protection so you get the rust-proof benefit of stainless while drastically reducing any chance of corrosion with the non-rust proof parts the stainless comes in contact with. 
• All products are Caster Offroad
