Spax T-STAR Plus – all-purpose Screw, Countersunk Head, T, 4Cut, Partial Thread, Stainless Steel A2, 1.4567 – 0197000350303, 0197000501003

Great screws. I used them to fix pieces of 18mm plywood together. After pre-drilling the first piece of wood (3mm) and countersinking the opening, and the screw sat very nicely and the fixing itself is very strong. To add, I recommend using an impact driver strength bit (T15) to fix the screws to avoid any wear.

Good quality and easy to use.

Just look closely at one of these screws to see what clever design features are included. The torx head means you should never damage on screwing tight. Often pilot holes and predrilled countersinks are not needed.Used for constructing garden play equipment - I can preassemble and then easily undo all screws for transport before reassembly. Being stainless they don't result in ugly rust stains after a few years use! Well worth the cost.

This are excellent screws which I used when building a picket fence which may need to be taken down occasionally. The manufacturing quality is top class, and in use the screws do everything they are supposed to. The only quibble I have is that my Torx20 bit tends to get pulled out of the bit holder because the fit into the screw-head is a little tight. Note - these screws are not magnetic, so they don't work with a magnetic bit holder. As far as I know all stainless screws are like this.

Best SL screws I've used. Strong, don't break and (sounds obvious) don't rust as many other stainless screws do due to their grade. Price is reasonable too and the torx heads make for easy use.

Solid quality product, surprised for the price you don't get a Driver bit included.

Great screw but expensive. Marked down a star due to the description not being clear enough as to what size screws this is for.

I particularly like these screws as the head allows zero slippage of the screwdriver. I have used a large part of the box and have experienced no problems at all even when screwing tinto very hard wood, without a pilot hole and using an electric driver. First class.
