i have been building a set of 4 adirondack chairs recently and i want them to be 100% made of materials made in the USA. The lumber is cypress and it is from Alabama, the finish is Sikkens Cetol 1( i believe its made in Troy, MI) the carriage bolts, washers and nuts i can find from a ton of places made in USA, but the stainless steel deck screws (#8×1 5/8 & #10×2 1/2) i cannot find any company that makes them in the USA. if anybody could offer any ideas it would be greatly appreciated. i am open to suggestions as far as different hardware, but i prefer them to be stainless steel. thank you for any inputs!
