Metallics JRMP78D – Frequently Asked Questions
1) Will a 3/8-16 x 1-1/2 machine screw thread into sheet metal or drywall on its own?
No. A machine screw like the JRMP78D has a blunt, fully threaded body with no self-drilling or self-tapping point, so it needs a pre-tapped hole or a mating nut. For enclosure work that means a tapped 3/8-16 boss or a nut on the back side. If you need a fastener that cuts its own thread into sheet metal, you want a self-tapping or sheet metal screw instead, not a machine screw.
2) How many screws come in the Metallics JRMP78D package?
100 pieces, supplied in a jar. The jar pack is handy for a service van or a shop bench where you are pulling a few fasteners at a time rather than opening a bulk box.
3) What is the exact part number to order this Metallics 3/8-16 x 1-1/2 screw?
Order it as Metallics JRMP78D. That part number covers the 3/8-16 x 1-1/2 round head Phillips steel machine screw in the 100-piece jar, and it is the only configuration the number refers to, so there is no length, drive or pack option to specify alongside it.
4) What is a round head Phillips machine screw typically used for in electrical work?
Round head Phillips machine screws like the JRMP78D are used to fasten into tapped holes on enclosures, panels, device mounting brackets, strut fittings and fixture bodies. The rounded head seats on the surface rather than countersinking, so it does not need a chamfered or countersunk hole. At 1-1/2 inches of 3/8-16 thread, it is the size you reach for when stacking a bracket or spacer and you need real grip length rather than a short panel screw.
