Metallics JTMSP143 – Frequently Asked Questions
1) What drive type does the JTMSP143 screw take, Phillips or slotted?
It has a combination drive (CD), which accepts either a Phillips bit or a flat blade screwdriver. Handy on service calls where you are not sure what is in the truck.
2) Is the Metallics JTMSP143 screw suitable for damp or outdoor electrical work?
The screw is zinc plated steel, which is a mild corrosion coating for dry interior use. For wet locations, exterior boxes, or coastal exposure, go with a stainless steel machine screw in the same 1/4-20 x 3 size instead.
3) Why use a truss head screw instead of a pan head on electrical fasteners?
A truss head is wide and low profile, so it spreads bearing load over thin sheet metal and sits flatter than a pan head. That matters when you are fastening through a knockout, a plate, or a slotted bracket where a taller head would interfere with a cover. The trade-off is less clearance for a deep driver recess and a head you cannot countersink.
4) How many screws come in the Metallics JTMSP143 package?
100 screws per jar. The jar pack is the shop-stock format, so it suits a service van bin or an MRO crib rather than a single fixture install.
5) What is the Metallics part number for the 1/4-20 x 3 truss head combo machine screw?
Metallics lists it as JTMSP143. The J prefix identifies the 100-piece jar pack of this 1/4-20 x 3 truss head combination drive zinc plated machine screw.
