Coaxial or twinaxial box 10 (Fig. 1) is held to I/O panel 15 by thumbscrew 20 so that male connector pins 25 engage with female connector 30. Box 10 has a slot 35 molded therein which engages I/O panel 15. I/O panel 15 is attached to power supply 40. Normally the I/O panel 15 is provided with an extruded tapped hole for receiving the threads of thumbscrew 20 which is captive in box 10. Standard manufacturing techniques, however, cannot hold the orientation of the extruded pole to the I/O panel to ensure alignment whereby the plastic thumbscrew 20 was caused to bend as the threads engaged. To eliminate this problem, two tabs 16 and 17 are formed from the I/O panel 15 with an angled profile, as in Fig.
