      Q:Can I use a regular star screwdriver bit for these or do you need the specialized bit that comes with the package?

      Answer This Question

      A:  The bit size is smaller than every other torx drive screw I have used. So yes, you will need to use the bit inside of the box.

      A:  While a star bit screwdriver will work, they will not have the Plus that is built into SPAX screws. The included bit has a extended recess to accommodate the extrusion on the T-Star+ bit. This feature reduces wobble. Thank you for being a SPAX customer.

        A:  The size is specific but a generic T8 will work.

        by|Jul 3, 2020

        A:  Any Star drive will work. Just so it fits the head of the screw.

        Q:WILL THESE WORK FOR ATTACHING DRYWALL TO CONCRETE WALL

        Answer This Question

        A:  they will not work in concrete

        by|Mar 26, 2021

        A:  Yes, this screw would work well in this application. Keep in mind the depth of the hole in the masonry needs to be 1" minimum and the hole must be cleaned out well to remove the sheet rock dust and concrete dust.

          A:  need to get concrete screws

          by|Jun 2, 2020

            A:  Yes. Selecting the proper masonry bit will be a challenge since it will require a small diameter bit. Conveniently Tapcon sells the appropriate bit with their fasteners.
