Metallics JMTMP408 – Frequently Asked Questions
1) What size and thread is the Metallics JMTMP408 truss head screw?
It's an M4 x 8 mm metric machine screw, so the thread is M4 and the length under the head is 8 mm. Being metric, it will not thread into a UNC or UNF tapped hole, even one that looks close in diameter like a #8-32.
2) Will an M4 x 8 machine screw work in a tapped hole or do I need a nut?
A machine screw like the JMTMP408 is made for a pre-tapped M4 hole or an M4 nut. It has no self-tapping point, so it will not cut its own thread in sheet metal. If you need to fasten into undrilled sheet, use a self-drilling or sheet metal screw instead.
3) Is the JMTMP408 a Phillips drive, and what head style does it have?
Phillips drive with a truss head. Truss heads are wide and low profile, which spreads the load over a larger area and keeps the head from protruding much, useful on sheet metal, enclosure covers and panel work where a standard pan head would stand too tall.
4) Are these Metallics M4 screws corrosion protected for use in electrical enclosures?
The JMTMP408 is mild steel with a zinc plating. Zinc gives basic indoor corrosion protection, which suits panel, enclosure and device work in dry interior locations. For wet, damp or exterior locations, specify stainless rather than zinc plated steel.
5) How many screws come in a jar of Metallics JMTMP408?
100 screws per jar. Metallics packs this item in a jar rather than a box, which is the format MRO and panel shops usually want on the bench or in the van.
6) What is the correct Metallics part number to reorder these M4 x 8 truss head screws?
Order Metallics JMTMP408. That single part number covers the M4 x 8 Phillips truss head zinc plated steel machine screw in the 100 piece jar.
