Rated 5 out of 5 by from Great screws Good grip with these screws. They countersink very well with no drilling.

Rated 5 out of 5 by from Good for no more ply Got these to replace the really expensive No More Ply screws. They work great, do have to pre drill and counter sink the panels but No More Ply's screws weren't brilliant at self drilling and pretty poor at countersinking into the surface, so would have had to do that anyway.

Rated 1 out of 5 by from PLEASE GO BACK TO OLD DESIGN Screwtite used to be in my opinion the best screws on the market because of their smooth uninterrupted shank which gave them great strength. These things came along with the underhead serrations which severely weaken the screw causing numerous head breakages and make the screw uncomfortable to hold when starting. I also had to remove so many steel splinters from my fingers after using them I threw the remainder away. Are these design changes really to improve the performance or are they to make them easier to manufacture? Please continue the original screwtite screws!

Rated 5 out of 5 by from Fast and true These were all straight and true, which is important in long screws, ripped into white pine easily at high speed and if needs be also came back out. There is a free bit in the box, but I only used it near the end so cant comment on the quality of that. Certainly better than a similar products bought elsewhere to finish off the job, they weren’t as straight and so wobbled on the way in and went as keen to self countersink at high speed, leaning a higher torque was neede.

Would these be good to secure floorboards and prevent squeaks?

Asked by: KJP95
Screw-Tite 2 would do the job but for total peace of mind and to eliminate squeaky floors completely you may want to use our Floor-Tite screws that are designed exactly for this purpose .

are these ok for osb board

are these ok to screw osb board in a shed , so will be inside. thanks paul
Asked by: dixonpaul
Thank you for your enquiry. These will perform well in OSB, depending on the thickness of the board, it may be worth drilling a pilot hole. These can be used internally on a shed but if there is any work externally, we would suggest something from our outdoor range such as Exterior-Tite® or Deck-TIte®.
