This 0 @ 1 @ indicates a pigeonhole for a screw with a cross recess ◇ A screw thread (2) is provided on the shaft (1), a screwdriver insertion part (4) consisting of a cross recess is provided on the head (8), and the screw Shaft (
1) A tapered hole (6) with a cross section similar to that of the driver insertion part (4) and a tapered hole (6) is inserted into the driver insertion part (4).
6. Provide two consecutively. This tapered hole (6) is made large enough to allow insertion of the tip of the detection rod (91 (see Figure 2 of the kite) of the electric meter III tester).

く、作業の安全性を向上させることかで自る。Figure 2 shows the ease of attaching the cable terminal (8) to the molded electrical terminal block (M) using the tapered hole screw (6) of the embodiment shown in Figure 1, and the tester's detection rod (9) I: Therefore, FIG. 3 is a perspective view showing a state in which measurement work is being performed. As shown in Figure 1, there is a tapered hole (5) from the screw head (set) to the shaft (1), so the tip electrode of the detection rod (9) is inserted into the tapered hole (5). Therefore, it is not necessary to hold the detection rod (9) by hand. Therefore, in electrical measurement, the adjustment of the holding force C between the detection rod (9) and the screw (6) which is the part to be measured is caused by There is no influence of contact resistance, preventing erroneous judgments and improving measurement accuracy.Since the detection rod (9) can be socketed into the tapered hole (S), there is no need to hold the detection rod (9) with one hand, making the work easier. It is self-sustaining by improving safety.

して実施できることは勿論である。There are cases where the screwdriver insert m5 (4) is worn out or deformed by pressure**, and becomes unable to transmit the rotational force of the screwdriver to the screw 12. The cross section is similar to that of the driver insertion part (-), and the tapered hole (i) at the tip a is connected to the driver insertion part (-).
) Since the openings are continuous, first use a Phillips screwdriver that is smaller in size than the Nine Phillips screwdriver or fa.
