Metallics JSS5161 – Frequently Asked Questions
1) What does a cup point set screw do differently than a flat or cone point?
A cup point bites into the shaft or mating surface and leaves a ring-shaped indentation, which gives strong holding on a hard surface and is the general-purpose choice for locking collars, pulleys, and couplings. A flat point is used when you don't want to mar a hardened or frequently removed shaft, and a cone point is used for permanent location in a drilled or center-punched spot. The JSS5161 is the cup point version in 5/16-18 x 1 inch.
2) Is the Metallics JSS5161 a hex key drive or does it take a wrench?
It's a socket drive, so it's turned with a hex (Allen) key, not a wrench. Socket set screws are headless and sit flush or below the surface of the collar or hub they're threaded into, which is why they're used where a protruding head would catch on a rotating part.
3) Is the black finish on this set screw suitable for outdoor or wet locations?
The JSS5161 is black steel, which is a plain carbon steel finish with no corrosion-resistant plating. It's for dry interior use. For damp, exterior, or washdown locations, choose a stainless 5/16-18 cup point set screw instead.
4) How is this 5/16 set screw packaged, and what's the part number to order?
Order Metallics part number JSS5161. It comes in a jar of 100 pieces, which is the format shops keep on the bench or in a van bin for repeat use rather than a one-off repair.
