Review on Prime Line 9054964 Screws Stainless 25 Pack by David Lesperance

Used to fasten floorboards in the attic. I was having a problem connecting wood to steel cross members and decided to cut and weld expanded metal I bought at a flea market for $5 and used these bolts with stainless steel washers fitted at the bottom as hidden gear, like seen in the photo. The second photo shows how the attic looks clean now. Old, weathered wood was salvaged from the boardwalk at Jacksonville Beach Pier that was destroyed by Hurricane Matthew. I think it looks good, had to be made of stainless steel due to the humidity in Florida.
