Suitable screws for fixing loose floorboards

chaoticj · 7 Feb 2018

Hi,

Need to fix down some wooden floorboards - about 20mm thick.

Believe I need 50mm screws but says online avoid where the shank is fully threaded.

Got some with smooth shank at top but it was 20mm of smooth so took back and swapped, now there is no smooth part.

Apparently the fully threaded ones hold the board too tight and will end up making it squeak..

What would be the best to use? Seen some 6 x 2" brass but again looks like loads of the shank is smooth? https://m.ebay.co.uk/itm/200-6-x-2-...476483?hash=item2f14443203:g:OLMAAOSwgyxWUhpM.

Thanks in advance!

inch & 3/4 No8's.
in your words - Smooth shank.

Fully threaded screws will cause 'Ramp-up' (when the point breaks through the board it lifts the board slightly and 'cause it is threaded into the board the screw will not pull the board down tight to the joist) which is the source of squeaks.

I agree with the suggestion for Tongue-Tite screws. They really work and the heads are unobtrusive
