This pack of 100 stainless steel 410 screws from FullerKreg comes equipped with a bright finish and Phillips drive, and it was primarily purchased for DIY applications. The self-drilling feature definitely saved time and effort as I drilled into metal, but the overall performance wasn't as expected. While some screws were fast to drill and secure, others stripped too easily or bent. The lack of consistency was disappointing since the manufacturer is known for high-quality products. Moreover, the full thread design didn't seem to help with grip, and I had to make sure everything was tightened securely. That said, the screws held up well against outdoor elements and didn't rust or corrode. Overall, the FullerKreg 8X1 Tek Screws are great options for some tasks, but not reliable across the board.
