Metallics JMFMP425 – Frequently Asked Questions
1) What size and drive is the Metallics JMFMP425 machine screw?
It's an M4 x 25 mm machine screw with a flat head and a Phillips drive, in zinc-plated steel. Order it by part number JMFMP425.
2) Is the M4 x 25 screw metric or imperial thread?
It's metric. M4 is a 4 mm nominal diameter metric thread, so it will not engage an imperial 6-32 or 8-32 tapped hole, which is what most North American electrical boxes and device straps use. Check the existing thread before swapping these in.
3) Does the M4 x 25 flat head Phillips machine screw need a nut or a tapped hole?
Machine screws like the M4 x 25 have a straight, uniform machine thread rather than a tapering wood or sheet metal point, so they thread into a pre-tapped M4 hole or take an M4 nut. They will not cut their own thread in plain sheet or wood.
4) Will the flat head sit flush in the panel or box I'm fastening?
The flat head on the JMFMP425 is a countersunk style, so it sits flush only if the hole is countersunk or the material is chamfered to match. In a plain drilled hole the head will stand proud; use a pan or round head screw instead if you cannot countersink.
5) Is a zinc-plated steel machine screw suitable for outdoor or wet locations?
The JMFMP425 is zinc-plated steel, which is a mild corrosion coating meant for dry indoor electrical work, enclosures, panels and device mounting. For wet, coastal or washdown areas, use a stainless machine screw instead.
6) How many M4 x 25 zinc machine screws come in a pack?
They're supplied 100 to a jar, which is how Metallics packages these small fasteners for a bench or service van rather than loose counts.
7) What does the 25 in M4 x 25 refer to?
Length, in millimeters: a 25 mm screw, roughly 1 inch. On a flat head screw that length is measured including the head, since the head sits down inside the countersink.
