These nuts were a perfect replacement for my VOX AC30CCH head input jacks that had both broken. Vox AC30CCH head has two input jacks that are fixed to a small PCB jumper cabled to the main board. The old nuts fell off and the PCB dropped inside the head. I ordered these to fix the input jacks back to their normal position coming out through the 'normal' and 'top boost' locations. The AC30CCH has plastic input jacks with a course thread. I tried a normal fine thread hex input jack nut and the thread did not match. These nuts are course thread for the plastic style input jacks.
