Abstract
The present invention relates to a screwdriver tool that loosens or tightens a screw nut, and is proposed by solving the problem that the screw nut is not worn or loosened by the driver tool tip when tightening or loosening the + (cross) type nut. It is an object of the present invention to provide a cross screwdriver structure in which a + (cross) tip portion 13 of a + (cross) screwdriver that is commonly used is combined with a-(date) tip portion 12.
Description
The present invention relates to a screwdriver tool for loosening or tightening a screw nut. The present invention relates to a screw driver tool that solves the problem that a nut groove is not worn or broken by a screwdriver tool tip when tightening or loosening a + (cross) nut. A combined cross screwdriver tool.
In general, it relates to a tool used to tighten or loosen a nut using a screwdriver of + (cross) or-(date) shape depending on the screw nut shape.
