    +1 for Wurth screws. They're proprietary and not cheap, but they do not slip.

    Failing that, Pozi are much better than Phillips, but not all Pozi screws are made equal; Hafele used to be fantastic, but they changed supplier and the recess in the new screws was just that little bit off and no Pozi bit would seat properly.

    Wera make really nice tips, not cheap though.

    Ironbark can be very hard, particularly if old and dry.

    Predrilling may be needed.

    What brand of screws are you using from the big green shed?.
    In my experience a lot of there screws are made by the same chocolate makers that Derik was visiting in Prague.

    Cheers Matt,

    Some flavour of Zenith 75mm timber screws. The screws are holding up - it’s the bits that are breaking.

    What are you driving them in with and what style of tip and bit holder are you using? If the tips are shattering they might be getting too much jarring torque than they can handle

    Zenith in my humble opinion are pretty average,is your screw driver on impact or just screwing?

    Builtex are slight better screws

    spray the whole box of screws with silicone spray before using, or, employ a teenager to scrape each one along a candle, the wax will lubricate them into the hardwood. I use the Irwin blue banded Phillips tips, and agree with the other poster about the Buildex , or preferably, Macsim branded screws. Zenith are rubbish we have found.

    Just partially drive the screw in and when you unscrew it, it has got warm, or even hot.
    Lay it on a piece of bees wax or candle wax, this will melt on to the screw and it will just screw in without any effort.

    This is no help to the thread but my father bought a box of irwin phillips head bits from bunnings a long time ago. He is a cabinet maker so did a lot of screwing and that box of 20 lasted until about last year or the year before. They were silver and I dont think they were 'impact rated' as this would have been before impact drivers were a thing but we used them with his impact driver without a problem. The best thing about them was that they worked really well with pozi screws too.

    I bought box of irwin bits after which are black and 'impact rated' at bunnings. I remember thinking the neck of these are really thin and thought maybe the modern ones have better metal. I broke one pretty much straight away and have since broken a couple more. These dont work at all with phillips head too which is sad as I'm pretty poorly organised so spending the time finding the pozi bits is a pain.

    They dont make them like they used to!

    Just on screw bits are there any good ones which are long and magnetised? there have been times I wanted to screw something deep in a hole and the magnetised bit holder is too fat

    Lastly, has anyone noticed that not all phillips are the same? My work has this screw driver set:
    Stanley 20 Piece Screwdriver Set | Bunnings Warehouse

    and the phillips in them adapt really poorly. Its like they're too pointy so the screw driver does seat fully into the screw head

    Just for clarification, I was linking to the Wera bits, not a specific type of head. I do not use posidrive. Look up Wera (and Wiha). These are the two premier screwdrivers in my opinion.

    Google for Wera diamond bits.

    Attach some rare earth magnets to the bit just behind the tip.

    I’m sure that I posted this before, but for those who did not see it, these screwdrivers are really easy to make if you have a lathe ...



    If you have one, it is also really easy to create a scratch awl using an extra or worn bit ...



    Chuck the screw bit in a drill and spin it against a disk sander. Scratch awl on left, birdcage awl on right ...



    Awl right then

    Hi Riverbuilder

    Agree that lubrication of screws is almost always a good idea, but I do not like silicone spray as you have to be so careful. Get a smidgeon on your work surfaces and it may impact adversely on future finishes.

    Usually I use lanolin, but almost any lubricant will work - softened candlewax, softened beeswax, parafin, butter, margerine, cooking oil, light machine oil - haven't tried sump oil!


    Cheers

    My thoughts exactly, Graeme.
