Hey everyone, sorry if this question has been posed before. I'm attaching swing hardware for my kids to the floor joists in my basement. Using 3/8" x 4" lag screws. Any real difference between zinc, galvanized, and stainless screws? I know there is for outdoor applications, but since I'm installing indoors and using for a kid's swing, not sure if there are any factors to consider. Thanks.
I'm building one of those tools that scrape snow off my roof. I'm trying to find spring-locked aluminum pole but I couldn't find any. All I found was flag pole and they do not have spring locked on those sectional pieces. Any suggestion is much appreciated.
