9/16 inch Diameter by 3 1/2 inch Long Stainless Steel Bolt

Quality product, worked perfectly for my new leaf springs

I agree with one of the other people that left positive feedback. I like the fact that this is a stainless-steel bolt to help prevent corrosion, I think that a longer shoulder would be better and could reduce the stress on the hanger bracket. I give it 5 stars ant=yway

The material is great, received exactly what I ordered to use while replacing leaf springs on my boat trailer. What I found impressive was how quickly the order was picked and shipped to me. No delay at all, this was extremely nice to see and allowed me to get my boat trailer ready for some prime fishing time. Thank you!

Replaced rusty bolts on work trailer hope these stainless bolts last way longer

I purchased this product to prevent rusted spring bolts again. The quality appears to be good. I prefer the shoulder to be longer on the bolt, because one side of the shackle and hanger rest on the threads.
