Metallics JMFMP850 – Frequently Asked Questions
1) What size and type of screw is the Metallics JMFMP850?
It's an M8 by 50 mm machine screw with a flat head and a Phillips drive, made of steel with a zinc plating. M8 refers to the 8 mm nominal thread diameter and 50 is the length in millimeters, so you need a metric-tapped hole or an M8 nut, not a #10 or 1/4-20 prep.
2) Will an M8 x 50 flat head screw sit flush in my panel or enclosure?
A flat head screw is designed to seat flush, but only into a countersunk hole. If the hole in your panel or enclosure bracket is straight-drilled with no chamfer, the head on the JMFMP850 will stand proud. For a straight hole you want a pan or round head machine screw in the same M8 x 50 size instead.
3) How many screws come in a jar of Metallics JMFMP850?
One hundred screws per jar. The jar pack is the sell unit, so an order of one gets you 100 of the M8 x 50 flat head Phillips machine screws rather than a loose count.
4) Is a zinc plated steel machine screw okay for outdoor or damp electrical work?
Zinc plated steel is a mild corrosion coating meant for dry indoor use, which is where the JMFMP850 belongs. Wet locations, washdown areas, or coastal exposure will rust it out. For those, specify a stainless M8 x 50 instead of the zinc plated version.
5) Does an M8 x 50 machine screw thread into sheet metal or do I need a nut?
Machine screws have a straight machine thread, so they do not cut their own threads. The JMFMP850 needs either an M8 tapped hole or an M8 nut on the back side. If you're fastening into bare sheet metal with no prep, use a self-tapping or sheet metal screw instead.
6) What part number do I order for the Metallics M8 x 50 flat head Phillips screw?
Order Metallics JMFMP850. That is the single manufacturer part number covering the M8 x 50 flat head Phillips steel zinc plated machine screw in the 100-count jar.
