Metallics JSS81 – Frequently Asked Questions
1) What size and thread is the Metallics JSS81 socket set screw?
The JSS81 is an 8-32 x 1 inch socket set screw with a cup point, in black steel. The 8-32 designation means a #8 diameter with 32 threads per inch, the standard machine screw thread that mates with a tapped 8-32 hole or an 8-32 nut.
2) Will the Metallics JSS81 thread into an 8-32 tapped hole on my existing fitting?
Yes, as long as the tapped hole is 8-32. The screw is a straight 8-32 thread and the usable length is 1 inch, so the hole or boss has to be deep enough to take as much of that inch as you intend to run in. If your part takes 10-24 or 1/4-20, this is the wrong screw.
3) How many screws come in a jar of Metallics JSS81?
Each jar holds 100 of the 8-32 x 1 inch cup point socket set screws. Metallics packs this one in a jar rather than a box or bag, which is how electricians and MRO stockrooms usually keep loose set screws on a truck or bench.
4) What is a cup point set screw used for in electrical work?
A cup point bites into the surface it is tightened against, so it holds a conductor or a shaft without needing a shoulder to seat on. On the electrical side that is the clamping screw in lugs, connectors, and fittings, and in general MRO it locks collars, pulleys, and knobs onto a shaft. The JSS81 gives you 1 inch of 8-32 thread to work with.
5) Does the JSS81 set screw need a hex key or a screwdriver?
It is a socket set screw, so it drives with a hex key (Allen wrench) seated in the head, not a screwdriver. There is no external head to grip, which is why these sit flush or below the surface of the part they are threaded into.
6) Is the black finish on the JSS81 suitable for outdoor or wet locations?
It is black steel, not stainless or galvanized, so treat it as a dry indoor fastener. For damp, wet, or exterior work, specify a stainless or plated set screw of the same 8-32 x 1 size instead.
7) Can I order the Metallics JSS81 in a different length or thread size?
The JSS81 is a single part number covering one combination only: 8-32 x 1 inch, cup point, black, 100 to the jar. Other diameters and lengths in the Metallics socket set screw line carry their own numbers, so order by the size you need rather than expecting an option on this one.
