Metallics JTMS50SS – Frequently Asked Questions
1) What thread size and length is the Metallics JTMS50SS thumb screw?
The JTMS50SS is a 1/4-20 thumb screw with a 1/2 inch length. The 1/4-20 designation means a 1/4 inch diameter coarse thread at 20 threads per inch, so it mates with any 1/4-20 tapped hole or nut.
2) Is the Metallics JTMS50SS thumb screw stainless steel, and will it hold up outdoors?
It is 18-8 stainless, the common austenitic stainless grade used for corrosion resistance in damp and outdoor conditions. That makes it a reasonable pick for exterior enclosures, wash-down areas, and coastal-adjacent work where a plated carbon steel screw would rust.
3) How many Metallics JTMS50SS thumb screws come in a pack?
They ship 100 to a jar, so one purchase covers a full truck stock or a panel-build run rather than a single fix. The jar packaging keeps the loose screws contained on a shelf or in a van bin.
4) Can I tighten these thumb screws without a tool?
Yes. A thumb screw has a knurled or winged head meant for finger tightening, which is why electricians use them on covers and panels that get opened repeatedly. With only 1/2 inch of 1/4-20 thread, it is intended for light clamping of a cover or bracket, not structural fastening.
5) What is the Metallics thumb screw used for in electrical work?
It is an electrical fastener, used where a cover, plate, strap, or small bracket needs to come off by hand. At 1/2 inch of thread it suits thin sheet metal covers and tapped bosses; for thicker stackups you want a longer 1/4-20 thumb screw.
