better place for fasteners

I'm a fan of Jamestown suppliers, but Fairwind can't be beat for Fasteners. Despite years of building wooden boats, I am still bewildered by screw sizes; metric, inches, gauge confusing as hell. But the website for Fairwind is excellent in helping a person figure out the dimensions of any screws or bolts you need, and I've found this to be a tremendous help. They even help when picking out the correct driver for a given screw size.Also Rob emails you back quickly to respond to any questions

Silicon brass hardware

I received all my brass hardware expeditiously and they came exactly as ordered. I used them for mounting thru hull water pick ups and strainers on my boat.

Washers

I ordered 2 each carriage bolts, fender washers, lock washers, regular washers and nuts. All we great. You should survey on the overall order and buying experience and not on the individual components within the order.

Silicon Bronze Fasteners

Recently purchased 6” Carriage bolts w/washers and nuts and received them right away. The only issue was one that was probably self-inflicted. I thought I was ordering the appropriate size washers for the 3/8”-16/6 carriage bolts but received #6 washers and that may have been my mistake. The project assembly timeline required I purchase the correct washers locally, but I’ll definitely be ordering future silicon bronze fasteners from Fair Wind. Thank You for your timely shipping!
