Metallics JSS2438 – Frequently Asked Questions
1) Will the JSS2438 screw into a 10-32 tapped hole?
No. 10-24 and 10-32 share the same number 10 diameter but have different thread pitches, so a 10-24 screw will cross-thread and gall in a 10-32 hole. Confirm the pitch stamped on the connector or the screw you removed. If the original is 10-32, order a 10-32 set screw instead.
2) What does a cup point set screw do differently from a flat or cone point?
A cup point, which is what the JSS2438 uses, has a hollow ring edge that bites into the mating shaft or bar and holds against rotation. That bite leaves a mark, so it's the choice where the part is staying put rather than being repositioned. A flat point is what you use on a hardened or finished shaft you don't want scarred, and a cone point is for permanent location into a drilled spot.
3) Do I need an Allen key for the Metallics JSS2438, or does it take a screwdriver?
It's a socket drive, so you need a hex (Allen) key, not a screwdriver. There is no slot or Phillips recess. A 10-24 socket set screw of this type takes a small hex key, so check the recess against your set before you're up a ladder with it.
4) Are these Metallics set screws meant for electrical work?
Yes. Metallics catalogues the JSS2438 as an electrical fastener, and 10-24 socket set screws in this size are the kind used to clamp conductors and bars in lugs, connectors, and ground clamps, as well as for securing collars and set-screw fittings. If your lug or connector calls for a 10-24 cup point set screw, this is the replacement.
5) How far will a 3/8 inch set screw reach into a lug or collar?
At 3/8 inch overall, the JSS2438 gives you the full 3/8 inch of thread to work with, since a set screw is headless and threaded end to end. Subtract your boss or lug wall thickness to see how much clamping reach is left on the conductor or shaft. If the wall is thick and the screw bottoms out before it bites, you need a longer length, not this one.
6) How many screws come in a jar of Metallics JSS2438?
Each jar holds 100 screws. The jar pack is the usual way these move for MRO and electrical service work, because loose set screws in a bag get lost and a jar stays on the shelf or in the van drawer.
7) What is the Metallics part number to order for a 10-24 x 3/8 cup point socket set screw?
Order Metallics JSS2438. That is the manufacturer part number for the 10-24 x 3/8 inch socket set screw with a cup point, packed 100 to a jar.
