### ⭐⭐⭐⭐⭐ As described , strong and easy to drill with.
*by J***. on 27 March 2025*

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.
