Motorola 0378372A01 Speaker Mic Thumb Screw for APX & XPR Radios

Motorola 0378372A01 Speaker Mic Thumb Screw for APX & XPR Radios

The Motorola 0378372A01 Thumb Screw is the replacement screw for Motorola APX and MOTOTRBO XPR remote speaker mics. It holds the speaker mic connector firmly on the radio’s side accessory port, so the mic stays connected in the field. Thumb screws get lost during accessory swaps, loosen over time, and wear out from repeated use. A missing or stripped screw can make the mic connection unreliable or let the mic come off the radio. Replacing it costs a few dollars and gets your speaker mic back in service without buying a new microphone.

Radio shops, fleet managers and public safety agencies often keep spare 0378372A01 screws with their APX 6000, APX 8000, SRX 2200, XPR 7550 and XPR 6550 radios.
