"I love these! Holds MDF tight with absolutely no splitting, just make sure to drill the pilot holes accurately. I also think the hex screw head gives a much more professional looking finish than a pozi drive where the heads are visible."
"Needed to add an additional cross member at rear of 300mm kitchen base unit to ensure that it was square. Used 15mm contiboard with 5.5mm pilot hole. Screws drove in smoothly with no splitting or blistering creating a strong, tight joint. Perfect results first time and only took minutes.Great product for DIYer and would be even better with a PZ3 head rather than hex."
"Ive used many ways to corner join mdf eg dowel. biscuits glue and pins, then one day I had to put a flat pack unit together using confirm screws and decided to try one on a piece of mdf offcut. From that minute onwads I was sold on using these screws for all my board corner fixings. Brilliant tight joint can work without having to wait for glues to dry. Also with the added bonus that the construction can also be dismantled easy."
"Highly recommended for dry fixing, chipboard, mdf, even timber, great screws. You must not forget to pre-drill as suggested. It will then hold together anything. Fixed many items since i bought it, looks like i will need more soon."
"Agree with other reviews. You need to drill straight, drill a clearance hole at 6.5 - 7mm through the board, then pilot the MDF edge with 5 - 5.5mm hole and the and drill a bit deeper so the screw can't bottom out. and countersink a bit.
Then it holds brilliantly and really this is the only screw that doesn't routinely split the MDF."
"I made a full set of Kitchen cabinets with 18mm MDF and these. Huge holding power and if they need to be visible, they gives a neat, professional looking finish. I found a 7mm countersunk clearance hole and a 5.5mm pilot hole worked best."
"Used these to create MDF loft boxes out of 12mm MDF (to save weight and cost). Yep, That's a 7mm screw into the end 'grain' of 12mm MDF without splitting. I used a 5.5mm hole a little deeper than the full length of the screw. Lining up the drill to make sure I didn't pierce through the side of the MDF was a precise job though!"
