Metallics JMFSC312 – Frequently Asked Questions
1) Will a flat head socket screw sit flush in my panel?
Only if the hole is countersunk. The JMFSC312 is a flat head socket cap screw, so it needs a chamfered or countersunk seat to finish flush with the surface. In a plain drilled hole the head will stand proud. If you need a screw for an un-countersunk hole, use a standard socket head cap screw or a pan head in M3-0.5 x 12mm instead.
2) Is the Metallics JMFSC312 a metric or imperial screw?
Metric. The thread is M3-0.5 and the length is given in millimeters (12mm), so it will not thread into an imperial tapped hole such as a 4-40 or 6-32. If the equipment you're working on uses 6-32 or 8-32 threads, you need an imperial machine screw instead.
3) What is the Metallics JMFSC312 screw typically used for in electrical work?
It's stocked as an electrical fastener, used for small machine-screw duty where an M3 tapped hole or M3 nut is involved: securing covers, brackets, device plates, terminal blocks, and small enclosure components. The black finish keeps the head from standing out against dark panels and devices.
