"Used to fix a uPVC door frame and found to be strong and dependable. Screwing into relatively soft breeze-block they were fine, tightened nicely, but when screwing into older, more dense concrete blocks the screws became tight with still about 20mm to go and could have snapped or damaged the pozi head. Instead I removed the screw, applied a bit of silicon lubricant to the thread and they then tightened nicely without fear of snapping. Would certainly use again and no problem recommending to others."
"I used the 135mm x10mm fixing screws to fit 2 new UPCV doors. The job could not have been more simple. First drill a 10mm hole, (using a 10mm Bosch multipurpose drill bit) through the frame to a depth of 135mm from the surface of the frame. Place the securing screw into the 135mm plug, turn just once, then, using a rubber mallet drive the screw and raw plug into the wall until the lip of the raw plug is flush with the side of the frame. Next, drive the screw fully home until it sits comfortably in the neck of the raw plug. Job done!
Everything went true to plan and these screws are holding the doorframe, with the door in place very securely indeed. It was really that simple!
I must have saved at least a £100 in not needing to pay the costs of a professional fitter.
For me both very good products. The Bosch multipurpose drill bit and the plugs/fixing screws are things that I am happy to recommend."
"These fixings are good value compared to the branded ones. Just make sure you have a good screwdriver bit and a few more than you need. If the bit slips on the screw head it'll probably wreck it. If this happens don't try to tighten again, it just gets worse, best to unscrew it and use a new one."
"These are useable but you need to have a high quality driver bit and concentrate on driving each one home cleanly and swiftly. Otherwise it's too easy to break one or have the crosshead gouged out and then it's a right pain to remedy."
"The catolgue states to use a 10mm drill. If you do there is insufficient space when yo screw in the fixing ardit snaps. I used a 22mm drill inthe end and they work then, only after snapping half the pack!"
