Metallics JSS12131SS – Frequently Asked Questions
1) What point style is on this 1/2-13 socket set screw, and will it bite into a shaft?
It is a cup point. The hollowed ring-shaped tip digs into the mating surface and resists backing out under vibration, which is why cup point is the default for locking a pulley, collar, coupling, or grounding lug onto a shaft or conductor. It does leave a mark on the shaft. If you need to clamp without marring, or you need to seat into a drilled spot or a V-groove, a flat point or cone point set screw is the better pick.
2) Is the JSS12131SS set screw stainless steel, and can it be used outdoors or in damp locations?
The screw is 18-8 stainless, the common austenitic grade used where plain steel would rust. That makes it suitable for damp interior locations, exterior enclosures, and washdown areas. 18-8 is non-magnetic in the annealed condition and holds up far better than a plated carbon steel set screw in corrosive air, though it is not the choice for direct saltwater immersion.
3) Does the JSS12131SS take a hex key or a screwdriver?
It is a socket set screw, so it is driven with an internal hex (Allen) key, not a screwdriver. The head is headless, meaning the screw seats flush or below the surface of the collar or lug it threads into.
4) What is the Metallics part number for the 1/2-13 x 1 stainless cup point socket set screw?
Order it as Metallics JSS12131SS. That number covers the 1/2-13 x 1 inch 18-8 stainless socket set screw with a cup point, supplied as a jar of 100.
5) How many screws come in the Metallics JSS12131SS pack?
One hundred screws, packed in a jar. The jar format is what shops stock on a parts shelf or in a service truck for repeat 1/2-13 set screw work rather than buying singles.
6) Is a 1/2-13 stainless cup point set screw used for electrical work or general mechanical work?
Both. Metallics catalogs this screw as an electrical fastener, and the typical use is locking conductors or hardware in a lug, collar, or clamp on an electrical assembly. Mechanically it is a standard 1/2-13 socket set screw, so the same screw works for sheaves, shaft collars, and couplings wherever a 1/2 inch coarse tapped hole is present.
