The screw councils, parks & pro crews trust
Double-thread fixing
The upper fixing thread pulls the board tight to the joist — no squeaks, no popped heads.
T-STAR plus T-25 drive
Positive bit engagement means almost no cam-out and far fewer chewed heads on a long run.
CUT point — no pre-drill
The serrated cut tip pushes timber fibre aside, reducing splitting on most hardwoods.
A2 / 304 stainless
Corrosion-resistant for exposed decks. Step up to A4/316 for coastal and saltwater jobs.

Before you buy
Do I need to pre-drill?
For most softwoods and many hardwoods, no. Near board ends or in dense hardwoods like Merbau, a quick pilot hole is good insurance.
304 or 316 stainless — which one?
A2/304 suits standard exposed decks. Within a few hundred metres of saltwater, step up to A4/316.
