A: No you need a longer screw
A: Sorry Rochhie, but with your fairly vague information, I’d have to say no. If you’re fastening 1-1/2 thick pine treads to metal supports, and if this is a deck and not an refined interior project, it may be better to use stainless or outdoor protected coated screws designed for self drilling and tapping metal. They must be long enough to pass through the supports so that an ample number of threads are through the metal, best if the screw heads are just below the tread’s surface and a good outdoor finish used for weather protection, especially using “softwood” as you said “pine”. Stair construction is serious when it comes to safety and failure is not an option, especially for insurance companies.
A: T15 is included you can purchase an extra at Home depot in a variety of lengths
A: The bit required is a T-15 and the box comes with one.
