Metallics JSS516516 – Frequently Asked Questions
1) Can I use the JSS516516 as a replacement set screw in a mechanical lug or connector?
Only if the existing screw measures 5/16-18 with a socket drive and a cup point. Thread pitch has to match the tapped hole exactly, so check the screw you pulled out, or gauge the hole, before ordering. Length matters too: at 5/16 inch, this one suits a shallow boss, and a deeper lug body may call for a longer screw of the same thread.
2) How many screws come in a jar of Metallics JSS516516 set screws?
100 screws per jar. Metallics ships this size in a jar pack, which is the usual bin-stock format for electricians and maintenance shops replacing set screws in lugs, connectors and fittings.
3) What tool do I need to drive these 5/16-18 socket set screws?
A hex key (Allen wrench). The JSS516516 is a socket drive set screw with no external head, so it's driven entirely from an internal hex recess, and it's tightened down below the surface of whatever it's clamping into.
4) What is a cup point set screw used for in electrical work?
The cup point is a recessed-ring tip that bites into the surface it bears on, which is why it's the standard point for clamping conductors in mechanical lugs, split-bolt and set-screw connectors, and for locking collars and fittings so they don't rotate. Metallics catalogs the JSS516516 as an electrical fastener for exactly that kind of service.
