Hi all,
I'n new to the group, recently joined to seek some information on my current project.
I'm in the process of rebuilding an old Pioneer SA-400 amplifier and am having trouble identifying the fasteners used through-out the unit. They're not standard metric threads, though the verniers measure the diameter of the 2 sizes used as 3mm/4mm. most of them are self cutting screws, but even the ones that aren't have the same thread.
They don't seem to be BSW or UN threads either. I've been down to the local screw shop and they are also unable to identify them.
is anyone able to help identify the screws?
thanks.

Thanks for the feedback. it seems in this case that they are neither metric threads or UNC and normal thread gauges can't identify them.Most were course metric but some were UNC.
Use a thread gauge to measure the size.
worse case if I can't figure them out is to drill the chassis threads out and replace with standard hardware..
