same screws the roofing supplier sells but way better price!Used for assembling a shed. Just what I needed and they arrived quickly.Metal roofing, .25 hex bit head. Screw was fine and as describes. Wish I saw a big multipack in 1.5". I would have lliked those a lot better. when finding the bullions for a more secure attachment to my roof.I will try to come back and add a short video if I can figure it out.They worked perfectlyUPDATE: VERY DISSAPOINTED. HE CHANGED HIS PRICES. I CAN DO MATH. GUESS ILL BE GOING BACK TO LOWES. Great product, timely delivery. Great for corrugated metal sheeting. I make garden boxes and the roofing screws are used to fasten the metal siding. Won't rust. Second time I've ordered from this buiz.I decided to use these screws to replace the thirty year old screws that were holding the siding on my mobile home. I wanted the washers, because some of the old screws had pulled thru the aluminum siding. These went in easy, and look good too. Hopefully it will be thirty more years before these have to be replaced.Fast delivery,great price,originalGreat product ,,,,,sharp point ,, bought large quantity for big project , used some on a small dog house project, worked great.
