Metallics JSS638 – Frequently Asked Questions
1) Is the JSS638 a cup point or a cone point set screw, and what does that mean for holding?
Cup point. The end is hollow-ground to a ring-shaped edge that bites into the mating shaft or bus and resists backing out under vibration. It leaves a visible ring mark, so if you need a finish you can rotate or reposition later, a cone or flat point is the better choice. For most grounding lugs, collars and set-screw connectors, cup point is the standard.
2) What driver do I need for the Metallics JSS638 screw?
It is a socket (hex key) drive, headless, so it drives with an Allen wrench rather than a screwdriver. Being a headless socket set screw, it sits flush or below the surface of the tapped hole once seated.
3) What material and finish are these 6-32 set screws, and will they hold up outdoors?
Steel with a black finish. That is a general-purpose indoor fastener; the black oxide type finish on steel offers very little corrosion resistance on its own, so for wet, damp or exterior locations specify a stainless set screw instead of the JSS638.
4) How many Metallics JSS638 screws come in a jar?
100 pieces per jar. The jar pack is what an electrical contractor or MRO stockroom wants on the truck or shelf for 6-32 set screw replacements, rather than a loose count.
