Metallics JSS71612SS – Frequently Asked Questions
1) What thread size and length is the Metallics JSS71612SS socket set screw?
It's a 7/16-20 x 1/2 inch socket set screw. The 7/16-20 is a fine thread, so it will only thread into a 7/16-20 tapped hole or lug, not a coarse 7/16-14 one. The 1/2 inch length is the full screw length on a set screw, since there is no head sitting above the hole.
2) Is the JSS71612SS a cup point or a flat point set screw, and where does cup point matter?
Cup point. The end is a hollowed ring that bites into the conductor or shaft when tightened, which is what you want on electrical lugs and connectors where you need the screw to hold against vibration and pull-out. If you're clamping a soft part you don't want marred, or you need a screw that seats flush against a flat surface without digging in, a flat point is the better choice.
3) Can I use the Metallics 7/16-20 set screw as a replacement on a mechanical lug or split bolt connector?
That's the normal use for a part like this, but match the thread before you order: it only fits a 7/16-20 tapped hole, and the 1/2 inch length determines how far it can advance into the conductor barrel. Measure the screw you're replacing and count the thread pitch. If your connector takes a coarse thread or a longer screw, this one won't seat correctly.
4) What driver do I need for these Metallics set screws?
They're socket (hex key) drive set screws, so you drive them with an Allen key or a hex bit, not a screwdriver. Headless socket set screws have the hex recess sunk into the end of the screw, so the key has to go straight down the bore of the tapped hole.
5) How many screws come in a jar of Metallics JSS71612SS?
100 screws per jar. The jar pack is how these ship, so it suits a service van or a shop bin where you're replacing set screws on connectors and lugs over time rather than buying a handful for one job.
