Review on Machine Finish Phillips M4 0 7 Threaded Fasteners for Screws by Ken Hamdan

I collect, repair and sell old stereos from the 70's and 80's. Sometimes the original black screws are missing or scratched and chipped. I found this thread size to fit almost all cabinets of the period. Attached is a picture of a JVC R-S300 with silver body screws. Now they merge with the dark body. I had the shorter 10mm length but had to go back as they were long enough, the 16mm length is perfect. And if I need a shorter one, I can just cut the end off with a dremel.
