I like the torque screws, I think you can get them from most builders merchants now

The screw head has 6 points, the same as they use in the motor trade

Thanks for the info.

Thanks for the info that's really useful.

Are pozi2 also marked as ph2? My power drill came with two dual ended bits one flat and one marked ph2. The latter seems to fit snuggly into some gold value pack 6m decking screws I bought recently from B&Q.

The head of the screw has a cross where the bit fits and this is disected by a diagnol cross, if get my meaning. Is this what you were referring to when you say the cross within a cross

It used to be much simpler in the old days when it was just flat or philips, even easier when it was flat or nothing!!

Edit

Just looked at eBay and see that PH2 are in fact Philips not pozi so how are pozi heads marked? There are some 25 DeWALT 25mm Ph2 Screwdriver Bits. Model: DT7909 which is the right ones could be worth getting as they are only £7 including delivery and although it doesn't say titanium it does say they are tough.

As I said the ph2 head I have seems a snug fit but could the screw heads be something else?

yes both driver bit and screw have a cross within a cross
where as philips are a simple x

although philips may seem to fit when you load up the screw they push out and chew up the head[cam out]

a good fitting bit will hold a screw underneath
you certainly shouldnt get any rocking of the screw on the bit

What's wrong with a Passlode somewhat quicker

If I'm not mistaken a Passlode is an air/gas nail gun? Good for the pro but even at eBay prices (£150) not cost effective for the odd job like the decking I'm going to build, but thanks for the thought anyway.

Seriously though ... I have spent weekends screwing down decking and I have used a Paslode, I promise you I will NEVER EVER screw a deck again still have the marks to prove it ... why not ..

No I don't work for HSS, in act I don't like them that much but at that day price you will be down the pub by lunchtime using a nail gun, or you will be screwing until mid-night (no pun intended!)

Worth checking out "Timberlock" screws for joining larger outdoor timbers. These have a hex head. Wickes have their own brand that are similar. I used them to fix some old hardwood railway sleepers together. It depends on the timber but in my case I was able to screw them 2 & 1/2 inches into a sleeper without a pilot hole. eg I was drilling a clearance hole through one sleeper only, one tap with a hammer to start them then a hex bit in my power drill to drive them in. They are black so you don't notice them once the sleepers are creosoted - otherwise you could countersink the heads or use dowel plugs. Some people say they are strong enough to pull a curved railway sleeper flat.
