Rated 4 out of 5 by from Straight into an RSJ Bought to hang a chandelier in a clients house. It weighed over 30kg and there was only a steel joist to screw into. These did the job perfectly. The thing I will say, I only needed 8 to hold the light but I used 16 or so as i found that once you had used one to drill the pilot in the steel, it was not great at going and threading itself the rest of the way. Change to a new one after the pilot bit had finished and it worked great. I was unable to pilot the holes with a drill first due to location but that might have saved me a few screws.

Rated 5 out of 5 by from My saviour I needed to screw one inch wood planks to a five millimetre steel box frame to make two gates. 110 screws to each gate 220 in total. Plenty of recharging batteries but the job was done, and not one dud screw!

Rated 4 out of 5 by from ok bought these to screw thu plastic decking into scaffold tube , not the best plan , if they get the center of the tube they might drill/ screw in , if 5mm off centre they slide off the side . so I had to drill a pilot first .. possibly not a fair test , probably ok drilling to flat surface .
