Metallics JPMP115BR – Frequently Asked Questions
1) What exactly is the Metallics JPMP115BR screw, and what do the letters in the description mean?
JPMP115BR is a 10-32 x 3 inch pan head slotted machine screw in brass, packed 100 to a jar. Reading the shorthand: PN is pan head, SL is a slotted drive (straight blade screwdriver, not Phillips), MS is machine screw, BR is brass. The 10-32 means a #10 diameter with 32 threads per inch, and 3 inches is the length under the head.
2) Will a 10-32 brass machine screw thread into my device box or fixture strap?
Yes, as long as the hole is tapped 10-32, which is the standard machine screw thread on outlet box ears, mounting straps, ground screws holes and most fixture canopies. A machine screw like this one needs a tapped hole or a nut, it will not form its own thread in sheet metal or wood the way a sheet metal or wood screw does.
3) Is 3 inches too long for mounting a device or fixture to a box?
At 3 inches, this is a long machine screw, meant for spanning a thick build up: deep plaster rings, stacked spacers, thick canopies or standoffs where a standard 1/2 inch to 1 inch device screw runs out of reach. For a plain yoke to box mount, it is more screw than you need and the excess will bottom out in the box. Order the shorter length in the same 10-32 thread for standard device mounting.
4) Do I need nuts or washers with these 10-32 x 3 inch screws?
Nothing comes with the jar but the screws. If you are threading into a tapped 10-32 hole, no nut is needed. If you are going through two unthreaded parts, add 10-32 machine screw nuts, and flat or lock washers if the joint will see vibration. Those are separate line items.
5) Why pick a brass screw instead of a steel one here?
Brass is the choice where corrosion or conductivity matters: damp and outdoor locations, marine or coastal work, and grounding and bonding points where a non ferrous, non magnetic fastener is preferred. It is softer than steel, so do not drive it with an impact driver, and do not over torque the slotted head.
6) Does the slotted pan head matter for an electrician's work?
Slotted heads are what most electrical trim screws use, so a standard flat blade or a combo tip drives this one, no Phillips bit needed. The pan head sits with a flat bearing surface and a rounded top, so it seats on flat sheet metal without a countersunk hole. If the assembly has a chamfered hole and needs a flush finish, you want a flat head instead.
7) How does the JPMP115BR come packaged for shop stock?
100 screws in a jar, which is how Metallics packs its fastener assortments for van and shop stock. One part number gets you the whole jar, not a single screw.
