Metallics JSS838SS – Frequently Asked Questions
1) Is the JSS838SS set screw stainless steel, and which grade?
It is 18-8 stainless, the austenitic grade commonly used for corrosion resistance in damp or outdoor electrical work. 18-8 is non-magnetic and softer than an alloy steel set screw, so for high-torque clamping on hardened shafts an alloy black-oxide set screw holds up better.
2) What does a cup point set screw do differently than a flat or cone point?
The cup point on the 8-32 x 3/8 JSS838SS has a hollowed, sharp-edged ring that bites into the shaft and resists rotation, which is the general-purpose choice for clamping a hub or collar. A flat point is the one to use when you do not want to mar the shaft or when the shaft is already flatted and will be reset often; a cone point digs deepest and is for a permanent location in a spotted shaft.
3) What size hex key drives an 8-32 socket set screw?
An 8-32 socket set screw takes a 5/64 inch hex key. There is no external head on the JSS838SS; the socket is internal, so the screw seats flush or below the surface of the hub it is threading into. Keep a 5/64 wrench with the jar.
4) How many screws come in a jar of Metallics JSS838SS?
100 pieces per jar. It ships as a jar pack, which is the usual format for a service-truck or shop bin item rather than a bulk box, so an electrician or maintenance tech stocking one size gets a usable count without overbuying.
5) What part number do I order for the 8-32 x 3/8 stainless cup point set screw from Metallics?
Order Metallics part JSS838SS. That number covers the 8-32 x 3/8 inch 18-8 stainless socket set screw with a cup point, supplied in a 100-piece jar.
