"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!"
