Reviews
TechFast Heavy Duty Self Drilling Torx Roof Screw 5.5 x 85mm (100 Pk) is rated 4.3 out of 5 by 36.
Rated 2 out of 5 by from Slow Was fixing into a 5mm c-section, so was slightly different to what it's intended for, but I found it was quicker for me to drill a pilot hole than to use this on it's own.

Rated 4 out of 5 by from Great product but buy longer than you think Great product but length add 20mm on to length of screw required because 20mm is the drill part or screw and its included in mwasurement of screw

Rated 5 out of 5 by from Brilliant Excellent goes through steel girders which are 10 mm thick

Rated 1 out of 5 by from Doesn hold well No good for light steel as it doesnt hold tightly

Rated 3 out of 5 by from Mostly good Using these to fasten down 2” timber to 8mm steel, some drill through the steel with ease, whereas others do not. Ended up drilling a 4.5mm pilot hole through the steel first and then winding these into it which was a much faster option.

Rated 5 out of 5 by from Impressive self tapping fixing. I'm really impressed with these, they self tapped through 6mm structural steel to S355 grade without too much problem to provide a nice strong fixing. I used approx 25 of these and only had one which malfunctioned as the head sheared off.
