Try buying wood screws in metric, they are a nonsense, not like the old 1" eights, or 2" black japped 6's, not confusing at all. ha ha.
who thinks these up???
Its like the screw heads, there are posidrive, cross head,phillips, slotted phillips, torx etc. different screwdrivers needed for each one.
I bought some decking screws, they gave a free screwdriver bit with them. good job they did, nothing on this earth will fit the screws, and the screwdriver bit will fit nothing else in the universe.
Good night,
