Metallics JMFMP516 – Frequently Asked Questions
1) Does the Metallics M5 screw need a tapped hole or will it cut its own thread?
It needs an existing thread. Machine screws like the JMFMP516 have a uniform machine thread and no cutting point, so they go into a tapped hole, a threaded boss, or a nut. If you are fastening into sheet metal with no thread, use a self-tapping or thread-forming screw, not this one.
2) Is M5 x 16 the right screw for a European-made panel or luminaire?
Yes, if the hole is tapped M5. The JMFMP516 is a metric fastener, M5 by 16 mm, which is a common size on imported panels, ballast trays, LED fixtures and DIN-rail accessories. It will not thread into an inch-series hole such as 10-32 or 10-24, even though the diameters look close. Confirm the tap on the fixture before ordering.
3) Will an M5 x 16 flat head machine screw sit flush in my enclosure or device plate?
A flat head screw is made to sit flush, but only in a countersunk hole. The JMFMP516 has an 82-degree-style flat head typical of machine screws, so the hole needs a matching chamfer or countersink. Drop it into a plain drilled hole and the head will stand proud. For a flat, untapered hole you want a pan or truss head instead.
4) Is a zinc plated steel screw okay for outdoor or damp locations?
Zinc plated steel, which is what St-Zn means here, is a dry-location and light-duty finish. It handles indoor panels, boxes and fixtures fine. For wet locations, washdown areas, coastal exposure or direct weather, go to stainless steel instead; the plating on a zinc screw will eventually give up and the head will rust in the countersink.
5) How many Metallics JMFMP516 screws come in a jar?
100 pieces per jar. The jar pack is what makes it practical for a service van or an MRO crib: one container of a single size rather than loose counts, so a maintenance tech restocking fixture and panel screws can standardize on M5 x 16 flat head Phillips across a facility.
6) What driver do I need for the Metallics JMFMP516?
A Phillips driver. On an M5 head that is normally a #2 Phillips bit. Use the right size and seat it fully, since a flat head sits down in a countersink and a worn or undersized bit will cam out and chew the recess.
