Metallics JMPMP425 – Frequently Asked Questions
1) What size and thread is the Metallics JMPMP425 machine screw?
It's an M4 x 25 mm machine screw, meaning a 4 mm metric diameter with a 25 mm length. Metric thread, so it mates with M4 tapped holes and M4 nuts, not with #6 or #8 imperial threads. If the enclosure or device you're fastening into is tapped imperial, this screw will not thread in.
2) Will an M4 machine screw work in a tapped hole, or do I need to drill and tap first?
Machine screws like the M4 x 25 need a mated thread, either an existing M4 tapped hole or an M4 nut on the back side. They don't cut their own thread the way a sheet metal or self-tapping screw does. If the sheet is untapped, you either tap it M4 or back the screw with a nut.
3) What head and driver does the JMPMP425 screw use?
Pan head with a Phillips recess, so you drive it with a Phillips bit. The pan head gives a rounded low-profile crown with a flat bearing face, which sits on the surface rather than countersinking, so no cone-shaped prep in the material is needed.
4) Are these M4 machine screws corrosion resistant enough for outdoor or damp locations?
The JMPMP425 is mild steel with a zinc plating. Zinc plated steel is intended for dry indoor use, panel work, enclosures and device mounting. For wet, exterior or corrosive locations you want stainless rather than zinc plated steel.
5) How many screws come in a jar of Metallics JMPMP425?
Each jar holds 100 of the M4 x 25 pan head Phillips screws. The jar pack is the handy size for a service van or a shop bin, one part number per jar rather than a bulk box.
