Square bits

Square bits fit screws with a square recess in the head. This category offers sizes 1, 2 and 3 in a length of 25 mm, and sizes 1 and 2 in a length of 50 mm.

Individual bits are handy for topping up a bit set or replacing a worn bit. You fit them in a bit holder or in a screwdriver or drill driver that takes bits.

All items in this category are made by Seneca. Alongside square bits, the individual bits range also includes Phillips bits, double-ended Phillips bits, Pozidriv bits, slotted bits, hex bits, Torx bits and bit holders, so you have the right bit for every screw profile.
