"Yes I would recommend these on the whole however I will tell you this: Usually I am all or nothing with reviews however these are non plus, I fixed polycarbonate sheets to a timber frame structure and 4 of the screws sheared off whilst driving them through the polycarbonate and the timber (Even with Pilot holes at 0.5mm less diameter than the screw to allow purchase of the screw). This is not ideal as they pierced the polycarbonate sheeting and then had to do a hole sealing job as well! Time consuming and unsure of whether they are going to be suitable for the job or not. Maybe these were just a faulty batch however!"
