As described , strong and easy to drill with.
Used these to attach 0.5mm metal cladding to battened wall. These are strong and hold tight. initially i used 4x19.mm tek screws but they did not grip tight enough, so i switched to these ones. They drill straight through the metal and attach easily and tightly. Drill Adaptor included.

Good product, does the job well!
I bought the HXJDAM 60-piece Roofing Screws with Rubber Washers (6.3×75 mm) for a corrugated metal roof project and they’ve been very good. The hex heads are easy to drive with a socket, and the self-tapping design cuts in cleanly. The rubber washers seem to seal well against leaks, and the zinc plating holds up nicely. A solid pack of screws that made the job quicker and gave me peace of mind.
