Metallics JTMP85SS – Frequently Asked Questions
1) Will an 8-32 truss head machine screw thread into a standard electrical box or device ring?
Yes. Steel outlet boxes, mud rings, and plaster rings are tapped 8-32, which is the standard machine screw thread for box-mounting and device work, and this screw is 8-32 with a 3/4 inch length. The wide truss head gives more bearing surface than a pan head, which helps when the screw passes through an oversized or slotted mounting hole.
2) Is the Metallics JTMP85SS screw stainless, and can it be used outdoors or in damp locations?
The screw is 18-8 stainless steel, the austenitic 300-series grade used for general corrosion resistance. That suits damp, washdown, and exterior-rated enclosure work where a plated carbon steel screw would rust. For chloride-heavy coastal or pool chemical environments, 316 stainless is the step up.
3) Should I use a truss head or a pan head 8-32 machine screw?
Go truss head, like the JTMP85SS, when the hole is oversized or slotted and you need the head to cover it, or when you want the lowest profile sitting against a cover plate or panel face. A pan head is the choice where the head has to drop into a counterbore or sit inside a tight recess, since a truss head's wider diameter can interfere.
4) Do I need nuts with these 8-32 machine screws?
Only if you're not threading into tapped material. The JTMP85SS is a machine screw, so it needs either a tapped hole (an 8-32 box, ring, strut nut, or channel insert) or a separate 8-32 nut on the back side. It will not form its own thread the way a self-tapping or sheet metal screw does, and no nuts or washers come in the jar.
5) How many screws come in a jar of Metallics JTMP85SS?
One jar holds 100 screws. Metallics packages these in a jar rather than a box, which is what you want on a service truck or bench where the fasteners get scooped by hand.
6) What is the Metallics part number for the 8-32 x 3/4 stainless truss head Phillips machine screw?
The manufacturer part number is JTMP85SS. That covers the 8-32 x 3/4 inch truss head Phillips machine screw in 18-8 stainless, jar of 100.
