Spax Countersunk Wirox Plus C4 Decking Screws 4.5 x 60mm Pack of 250
Great German build quality locks the deck boards in tight. Cant really comment on reliability as have only just laid but I dont see there being any problems.
Best feature is the torx head so you can remove boards easily.

Best buy by far!
Purchased these after reading other reviews; they didn't lie...
No pre-drilling reqd; even into green oak...
Over 1000 screws later and all went in tirelessly... and all with the driver bit included from the first box!
More than can be said for other screws used on same project...
SPAX hasn't let me down yet.

best for the job
You can get cheaper, but these are probably the best.
Used on decking and raised beds. The star head gives a very positive drive and the stainless steel is still in good condition after two years of Dorset weather!
I had to remove a few to do some alterations. Came out no problem and were reusable. Normal screws rust away after six months.

Very clever screws
With the little head these screws are perfect for narrow plank decking. I've been using them on western red cedar deck boards and they don't need pilot holes and don't split the wood, even close to the end of the boards. They seem to drill themselves into the wood and then countersink the head with no effort at all - even though they are straight sided on the head. They work really well on cedar with hardly any mushrooming around the countersunk head.
In terms of cost, these are actually much cheaper than standard stainless steel deck screws. I know they're not stainless steel but they should last just as long. Still it would be good to get them in a larger box - 250 is only a quarter of my deck.
