Rated 5 out of 5 by from A 'tite' job Bought these screws mainly because of their precise length and width. Hadn't used Tite screws before so was extremely pleased with their bite and hold capabilites. Will definitely use these screws and the brand more often from now on.

Rated 5 out of 5 by from Time saving excellent screw Bought these to make some 18mm MDF cabinets and have not been disappointed. They drive straight through the board and into the edge of the adjoining one without pre-drilling and without splitting. They do emit a significant squealing sound which can be a bit disconcertingm but a pilot hole eliminates this if required.

Rated 5 out of 5 by from Tight hold Bought these to join two pieces of MDF for a bath panel. Used 7 screws into 3mm drilled holes and was very happy to see that the panels were solidly fixed together.

Rated 5 out of 5 by from Awesome screw for Mdf Great screw for mdf, I still pilot a hole to avoid potential for splitting, but the hold on these is far superior to others I've used.
