Metallics JSS121312SS – Frequently Asked Questions
1) Is the JSS121312SS a cup point set screw, and what does that mean for holding a shaft?
Cup point, yes. The end of the screw is a hollowed ring that bites into the mating shaft or bar and leaves a permanent ring-shaped mark, which is what gives it the holding power. Use it where the part is not meant to be repositioned often. If you need to locate against a drilled seat or avoid marring a finished shaft, a cone, flat, or oval point set screw is the better choice.
2) Are these Metallics set screws stainless, and will they hold up outdoors or in a damp vault?
They are 18-8 stainless steel, the standard austenitic grade used for general corrosion resistance. That makes them suitable for damp, wet, and outdoor electrical work such as exterior gear, pull boxes, and below-grade enclosures where a plain carbon black-oxide set screw would rust. 18-8 is not the grade for chloride-heavy marine exposure; 316 stainless is the step up there.
3) Can I use a 1/2-13 stainless cup point set screw for electrical lug and connector applications?
That is the intended lane for this one, it's stocked as an electrical fastener. 1/2-13 socket set screws with a cup point are typically used to clamp conductors and bars in mechanical connectors, split bolts, and set screw lugs, and the 18-8 stainless body suits wet or corrosive locations. Match the thread to the connector body's tapped port, 1/2-13 will not thread into a 3/8-16 or 5/8-11 port.
4) What driver do I need for the JSS121312SS set screw?
It's a socket (internal hex) set screw, so it drives with a hex key, not a screwdriver or wrench flats. There is no head above the surface, which is the point of a socket set screw, it seats flush or below in the tapped hole.
5) How many set screws come in a jar of the Metallics JSS121312SS?
100 pieces per jar, packaged in a jar rather than a box or bag, which is how shop-floor and service-truck quantities of small fasteners are usually carried. Order quantity is in jars of 100, so a job needing a dozen screws still takes the full jar.
6) What is the Metallics part number to order for the 1/2-13 x 1/2 stainless cup point set screw?
Order it as Metallics JSS121312SS. That single part number covers the 1/2-13 x 1/2 inch 18-8 stainless socket set screw, cup point, in the 100-piece jar.
