Metallics JSS121CONE – Frequently Asked Questions
1) What does the cone point on this 1/2-13 socket set screw do, and when should I use a different point?
The cone point on the JSS121CONE is a sharp tapered tip that bites into the mating part and gives the highest holding power of the common set screw points, so it is used for permanent or semi-permanent positioning, typically into a spotted or drilled seat on a shaft or bus bar. Because it digs in, it marks the part. If you need to reposition or reuse the shaft, a flat point or cup point set screw is the better choice; a cup point is the usual general purpose option for repeated service.
2) Does the Metallics JSS121CONE need an Allen wrench or a screwdriver?
It drives with a hex key. This is a socket set screw, meaning it has an internal hex recess in the end rather than a slot or external head, so you need an Allen wrench (hex key) sized to the socket. There is no head to grip with a wrench or driver.
3) Will a 1/2-13 socket set screw sit flush in the hole, or does it stick out?
A socket set screw is headless, so the full 1 inch length threads into the tapped hole and it can be driven below flush if the hole is deep enough. That is why set screws are used in lug bodies, collars, and connectors where a projecting head would interfere or create a clearance problem. Make sure your tapped depth is at least the 1 inch length if you want it fully recessed.
4) Is this set screw meant for electrical work like lugs and connectors?
Yes. Metallics catalogues the JSS121CONE as an electrical fastener, and a 1/2-13 cone point socket set screw in that trade is typically used to clamp conductors or position parts in mechanical lugs, tap connectors, clamps, and similar hardware with a 1/2-13 tapped seat. For conductor clamping, follow the connector manufacturer's torque spec rather than running it down by feel.
5) How many screws come in the Metallics JSS121CONE package?
They ship 100 to a jar. That quantity suits a service van or MRO crib stock where a 1/2-13 set screw is a recurring replacement item rather than a one-off, and the jar keeps them from scattering in a parts drawer.
6) What is the Metallics part number for the 1/2-13 x 1 cone point socket set screw?
The manufacturer part number is JSS121CONE. Use that exact number when ordering, since the Metallics set screw line splits by point style and the cone point is a distinct item from the flat and cup point versions in the same 1/2-13 x 1 size.
