Rated 4 out of 5 by from No problems Installed 40 of these recently without any issues. Yes, the screw heads are a bit soft but having read the reviews I drilled out shallow pilot holes and took it steady on the power driver and they all went in okay. The plastic caps were stiff and difficult to seal down - but it was only 4 degrees.Warming them up in hot water made life easier. TIP: Get more than you think you'll need.

Rated 5 out of 5 by from Hardened steel roofing screws I brought these to fix down corrugated pvc sheets to my new shed, they worked like a dream. "Couldn't give five stars for reliability as I have only had them in for a few days. But all in all a great product and well worth the money!

Rated 5 out of 5 by from Roofing Screw Did exactly what I needed it for, plastic screw cap is a great feature and protects the screw from corrosion

Rated 2 out of 5 by from On the whole these are OK 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!
