Metallics JSS3258 – Frequently Asked Questions
1) Are these black set screws steel, and are they suitable for outdoor or wet locations?
They are black steel, not stainless. The black oxide type finish on steel set screws gives only light corrosion resistance, so keep these to dry indoor electrical work: panel and enclosure interiors, fixture bodies, indoor lug and shaft applications. For damp, wet or coastal exposure, specify a stainless steel set screw instead.
2) Can I use a 10-32 set screw to replace a missing screw in a lug or a lamp holder?
If the existing tapped hole is 10-32 and you need 5/8 inch of reach, yes, the JSS3258 drops in. Check two things first: back out a neighbouring screw and confirm the thread is 10-32 rather than 1/4-20 or 8-32, and confirm the original was a headless socket set screw and not a slotted or hex head screw, because a set screw leaves no head above the surface to clamp a washer or a strap.
3) Is the JSS3258 a cup point set screw or a flat point?
Cup point. The JSS3258 is a socket set screw with a cup point, which is the general purpose choice: the hollow ring on the tip bites into the mating shaft or conductor and resists backing out. If your application needs to seat flush against a soft surface without marring it, a flat or oval point screw is the better pick instead.
4) What tool drives these 10-32 set screws?
A hex key. These are socket (internal hex) set screws with no external head, so they drive from an Allen wrench or hex bit and sit fully below the surface of the tapped hole. There is no slot or Phillips recess on them.
5) How many screws come in a jar of Metallics JSS3258?
100 pieces per jar. These ship in Metallics' jar pack, which is the format electricians keep on the van or in the shop bin because the lid reseals and the small parts do not scatter.
6) Does the JSS3258 come in other lengths or thread sizes?
The JSS3258 is a single configuration: 10-32 thread, 5/8 inch length, cup point, black steel, 100 to a jar. If your tapped hole needs a shorter reach so the screw does not bottom out, or a larger thread, that is a different Metallics part number rather than an option on this one.
