Metallics JSS51614 – Frequently Asked Questions
1) Will a 1/4 inch long 5/16-18 set screw be long enough for my lug?
At 1/4 inch overall, the JSS51614 is a short set screw, so it suits tapped bosses roughly a quarter inch deep or less and will not reach far into a deep conductor barrel. If the original screw you removed is longer, measure it and match the length rather than substituting this one, or it will bottom out on the thread before it clamps the conductor.
2) Is the JSS51614 a cup point set screw, and what does the cup point do on electrical connections?
Cup point, yes. The cup tip is a hollow ring that bites into the surface it is tightened against, which is what you want on an aluminum or copper conductor or a shaft, since it digs in and resists loosening under vibration. It is not a flat or cone point, so expect it to leave a mark on the conductor.
3) What drive does the Metallics JSS51614 set screw take?
It is a socket (internal hex) set screw, so it is driven with an Allen key or hex bit, not a screwdriver. The head is headless, meaning it seats flush or below the surface of the tapped hole once tightened.
4) Is the JSS51614 screw steel or stainless, and can I use it outdoors?
Steel. These are plain steel set screws, so for wet, coastal, or buried locations you want a stainless or corrosion-resistant equivalent instead. Indoor panel, gear, and connector work is where the steel version belongs.
5) How many Metallics JSS51614 set screws come in a jar?
100 pieces per jar. The jar pack is the standard shop or van quantity for replacing lost or stripped set screws in lugs and connectors, so you are buying the full 100, not an individual screw.
