I recently converted my van into a tiny house and used a lot of these screws to attach things. I think I bought 3 packs and they work great. For the price they are unbeatable. I paid $3 for 2 house shares when I didn't know any better. I got 18 for $6 lowest price. What annoys me the most is that the screws aren't magnetic and it drives me crazy when they keep falling off the drill. But for the price it's 100% worth it!
