Self drilling screws
16 May 2013
By Mggareth
, South Wales
"I used these to mount sheets to the metal side frame of a carport. I must admit I did not think they would work, but they did. We have had some strong wind and rain to give it a good test, but all is well. They were the death knell of my old drill, you really do need a good drill to drive these. I would not hesitate to use them again."

Good Quality Product
6 Apr 2013
By Chrispbaconrollwithbutter
, Winsford, Cheshire
"Bought a bag of these expecting the drilling tip to be next to useless. I built a car port using box section steel and used these to fix the roof sheets. Was expecting to have to pre-drill the holes with a pilot drill at least but I gave one a go and it drilled box section no problem even when drilling at arms length and not being able to apply much pressure to the drill. Out of the bag of 100 I had 2 which where a bit dull and would not drill quick enough. I simply used another to drill the hole and put the dull one back in to fix the sheet. The one I had used to drill the hole drilled a second hole no problem. Going back tomorrow to get another 100 as I didn't have enough."

"WE USE THIS PRODUCT IN MANY AND VARIED WAYS, EVEN AS A DRILL BIT WHEN THE NEED HAS ARISEN. THEY LEAVE LITTLE OR NO MESS AND VERY EASY TO USE.

IF THE EDPM WASHER TYPE IS USED EVEN PROVIDES A WATERPROOF FIXING,ALL IN ALL A GREAT PRODUCT."

Self Drilling Screws
19 Jul 2012
By lukizade
, RHONDDA VALLEYS
"I purchased these to attach PVC window frames and door frames to galvanised pipes for a greenhouse project.
They did the job brilliantly after I drilled a pilot hole prior to fixing and they held the frames in place very securely, I also used them to secure Galvanised roofing sheets into times supports where they cut through and secured into the timber effortlessly and they seal the drill hole really well against the weather-well happy

"even though these are quoted for steel to steel fixing, i used them for steel to wood. self drilling point makes the whole job easier and faster. 8mm hex nut on top gives great grip with no screwdriver slipping. good value pack with more than enough for most jobs."

Very poor product
17 Nov 2012
By Strima
, St Neots
"The screws advertised are bright however the one's supplied have a matt and dull coating but that's purely cosmetic.
For self drilling screws they struggle to get through the poorest of metals as the cutting edges dull quickly even at slow speeds.
Once they've finally cut through the cutting threads are so shallow they strip out the hole easily leaving a loose fitting.
The hex head is slightly rounded so they do not sit properly in the socket and wobble around.
All in all a very poor product, buy cheap, buy twice."

Waste of time.
7 Aug 2012
By Triplesolar
, London, East
"These are the most useless tek-screws you could buy. They can't even go through 1.5mm aluminium with out burning out the tips. Was in a hurry so purchased 500 from 3 different stores but it ruined my mood and the job.
Purchased different ones from a fastening shop and they worked brilliantly. Cheap, poor inferior metal used. Avoid at all cost. Will make the job a nightmare. Unfit for the purpose of drilling through soft metal. Tips burnt and snapped if tightened.
Screwfix need to get a new supplier or manufacturer as the metal is not the correct grade."
