Metallics JTMS1038 – Frequently Asked Questions
1) Will a 10-32 truss head machine screw work for mounting a device or cover plate in a steel electrical box?
Yes. 10-32 is the standard thread used for grounding and device mounting in steel outlet and junction boxes, and the Metallics JTMS1038 is a 10-32 x 3/8 inch slotted truss head machine screw in zinc plated steel. The 3/8 inch length suits a tapped box ear or bracket where the screw only needs to pick up a few threads; if you are stacking a plaster ring or a thicker bracket, you will need a longer 10-32.
2) What does the truss head on the Metallics JTMS1038 screw do differently than a pan head?
A truss head is wider and lower in profile than a pan head, so it spreads the load over a larger bearing surface and sits flatter. That matters when you are holding down thin sheet metal, an oversized hole, or a cover where clearance behind a plate is tight. It drives with a flat blade screwdriver, since the JTMS1038 is slotted.
3) How many 10-32 x 3/8 truss head screws come in the Metallics JTMS1038?
One hundred screws, packed in a jar. The jar format is what shops keep on the bench or in a service van for device and box work rather than a loose bulk bag.
4) Is zinc plated steel okay for these screws outdoors or in a damp location?
Zinc plating on steel is a mild corrosion coating meant for dry indoor use. For wet locations, exterior boxes, or washdown areas, specify a stainless machine screw instead. The JTMS1038 is zinc plated steel, so keep it to interior work.
5) Can I use a 10-32 machine screw like this to tap into a self-drilling hole in sheet metal?
No. The JTMS1038 is a machine screw, so it needs a pre-tapped hole or a nut. Boxes and brackets with factory 10-32 tapped holes are fine; bare sheet metal needs a self-drilling or sheet metal screw, or you tap the hole first.
6) What part number do I order for the Metallics 10-32 x 3/8 truss head slotted machine screw?
Order Metallics JTMS1038. That is the full designation for the 10-32 x 3/8 slotted truss head machine screw in zinc plated steel, jar of 100.
