Metallics JTMS14 – Frequently Asked Questions
1) What size and thread is the Metallics JTMS14 truss head machine screw?
The JTMS14 is a 1/4-20 x 1 inch truss head slotted machine screw. 1/4-20 means a 1/4 inch nominal diameter with 20 threads per inch, so it mates with 1/4-20 tapped holes and standard 1/4-20 nuts, not with a sheet metal or self-tapping hole.
2) Will a 1/4-20 truss head machine screw thread into a strut channel nut or a tapped box?
Yes, as long as the threads are 1/4-20. The JTMS14 is a machine screw, so it needs a pre-tapped hole, a channel nut, or a nut on the back side. It will not cut its own thread in sheet metal or drywall. Grip length is 1 inch under the head, so account for material thickness plus full nut engagement.
3) Why use a truss head instead of a pan or round head screw?
A truss head is wide and low, so it spreads bearing load over a larger area and sits closer to the surface. Electricians use that on cover plates, device straps, and sheet metal where a pan head would pull through an oversized hole or stand too proud. The JTMS14 drives with a flat blade, since it is slotted rather than Phillips.
4) Is the Metallics JTMS14 screw suitable for outdoor or damp locations?
It is zinc plated steel, which is a mild corrosion coating meant for dry indoor use. For wet, exterior, or corrosive locations, specify stainless steel fasteners instead. Zinc plating will eventually rust if it sits in weather or condensation.
5) What part number do I order for the Metallics 1/4-20 x 1 truss head machine screw?
Order Metallics MPN JTMS14. That number covers the 1/4-20 x 1 inch slotted truss head zinc plated steel machine screw in the 100 count jar.
