Rated 1 out of 5 by from Useless Used these screws for 47mm deep c16 timber. If I didn’t pilot drill the screws either bent or the head stripped. If I tried to back them out they just sheared off. Even after pilot drilling, if you make one slight slip then the head strips out.

What size PZ bit do these take?

I was quite surprised that 1300 screws did not come with a single bit in the box. The spec says the bit is a PZ. What size PZ do I need to buy?
Asked by: DavidRIch
Hello. The size bit that you require for 4.5mm is PZ#2. Hope that helps. Thank you for using Q&A. MH

Interior floorboards

Can i use these exterior deck screws for internal softwood straight edged floorboards as they are cheaper than specialist floor screws? I do not want to end up with squeeky floorboards and i do not want to use nails.
Asked by: BotchitAndScarper
Hello BotchitandScarper Whilst these screws could be used indoors they are primarily designed for outdoor use where corrosion resistance is required. I would advise speaking with a local qualified floor layer and asking their advice as to the type of screw to use if you don't wish to use nails. Thank you for using Q&A (CW)

Are they suitable for Tanalith (Copper Azole) threated wood?

Asked by: ifcho
Hello, After some research we believe these would be suitable, if at all possible you may wish to do a patch test on an inconspicuous area first to be 100% sure. Thank you for using Q&A.
