Document Type and Number:
WIPO Patent Application WO/2021/153252
Kind Code:
A1
Abstract:
A jig for a fastening member is provided which enables easily and accurately screwing the threaded part of the fastening member at a prescribed torque. This jig (11) for a fastening member is provided with a first engagement part (11a) which can engage in the direction of rotation with a cross groove (12c) of a screw (12) having a threaded part (12a), and the second engagement part (11b) which can be engaged in the direction of rotation by a Phillips screwdriver (15). The first engagement part (11a) of this jig (11) for a fastening member engages with the cross groove (12c) and, in a state in which the Phillips screwdriver (15) has engaged with the second engagement part (11b), when the rotational torque that is transmitted from the Phillips screwdriver (15) to the cross groove (12c) reaches a preconfigured set torque, the first engagement part (11a) deforms, rendering the rotational torque non-transmissible.
