Rated 5 out of 5 by from Perfect screws Ideal for fixing flooring.Makes installing floors much easier

Rated 5 out of 5 by from Great product I needed to screw down old pine floorboards prior to sanding. I was a little skeptical of these, but they're great. They have enough pulling power to secure to boards and can barely be seen, unlike if you use standard wood screws and countersink etc. One down side is you need to be careful when screwing as the head is small, so even pressure is needed. I'd use again for sure.

Can I use this screw for 18mm t&g OSB loft boards fixed to plastic loft legs?

Asked by: SunnyJim75
Tongue-Tite screw 3.5x45mm would be ideal for fixing OSB boards but if you are fixing into plastic we would recommend using a thicker gauge screw.

Hi could these be used to fix 12mm tongue and groove to an osb wall on the inside of a summerhouse ?

Asked by: Lates
Yes these could be used but we would recommend using our Tongue-Tite Plus which are Stainless Steel and ideal for outside jobs.

Would these work for redwood T&G floorboards??

And I'm guessing redwood would be more likely to split that hardwood, so pilot holes would probably be needed too?
Asked by: AlanMidlands
Thank you for your enquiry. Tongue-Tite® will work well in this application. We would always suggest, where there is a chance the timber may split of first drilling the appropriate pilot hole.

Wall Plug

Can I use this screw with 6mm diameter / 40mm length red wall plug to screw skirting into concrete?
Asked by: Aran30
Yes it should be fine but you need to take into account how thick your skirting is. For example 45mm screw minus 15mm skirting will leave 30mm into the wall plug. You can always drive the Tongue-Tite screw further into the board to give an extra 5mm as this screw has a very small head.

Is it best to put a screw in for every joist? And I’m guessing it’s just along one edge as the other edge is in the groove of the last?

Asked by: Wesley34
Thanks for your enquiry. Yes we would recommend screwing at each joist point and only in the tongue of the board. Hope this helps.
