Metallics JSS52438SS – Frequently Asked Questions
1) Will a 3/8 inch long set screw be long enough for my connector?
At 3/8 inch of overall length, this is a short set screw meant to sit flush or below flush in the boss it threads into, with just enough reach to clamp a conductor or shaft sitting directly under it. If your set screw has to cross a thick wall or reach down into a deep pocket, measure the screw you pulled out: anything longer than 3/8 inch in 5/16-24 means a longer screw, not this one.
2) How many screws come in a jar of the Metallics 5/16-24 x 3/8 socket set screws?
They ship 100 to a jar. The jar pack is how Metallics bundles small fasteners for a shop drawer or a service van, so one order gives you a bin quantity rather than a single piece.
3) What is a cup point set screw used for in electrical work?
A cup point has a hollowed, sharp-rimmed tip that bites into the surface it's tightened against, which is why it's the common point style for clamping conductors in lugs, connectors, and mechanical set screw terminals. The Metallics JSS52438SS is that style in 5/16-24 x 3/8, and it's catalogued for electrical use. Cup point leaves a mark in the conductor or shaft, so if you need a removable, non-marring hold you want a flat or nylon-tipped screw instead.
4) What driver do I need for the Metallics JSS52438SS set screw?
It's a socket set screw, so it drives with a hex key (Allen wrench) in the internal socket, not a screwdriver or a wrench on the outside. There's no head to grip, which is the point: the screw seats entirely inside the threaded boss.
5) What is the exact part number to order these Metallics 5/16-24 set screws?
Order Metallics part number JSS52438SS. That's the single model covering the 5/16-24 x 3/8 cup point socket set screw in the 100-count jar.
