Metallics JBSC638 – Frequently Asked Questions
1) Will a 6-32 socket button head cap screw thread into a standard 6-32 tapped hole or nut?
Yes. The Metallics JBSC638 is a 6-32 UN thread at 32 threads per inch, cut to ANSI/ASME B1.1, so it mates with any standard 6-32 tapped hole, nut, or threaded insert. Shank length is 3/8 inch, so the hole needs at least that much usable depth if it is blind.
2) Do these Metallics screws qualify for a Buy American or ARRA-funded job?
No. The JBSC638 is not Buy American compliant and is not ARRA compliant. Country of origin is listed as multiple. If your project carries domestic sourcing requirements, you need a domestically produced fastener.
3) What size hex key drives these Metallics button head screws?
They take a hex (Allen) key, not a screwdriver. The socket is a hex drive with a slot depth of 0.044 inch, so a short-arm key or a hex bit seats fully in a shallow recess. Head width runs 0.25 to 0.262 inch and head height 0.063 to 0.073 inch, which is what gives the low-profile button look.
4) How are these 6-32 x 3/8 screws packaged and what is the minimum I can buy?
They ship in a jar, 100 pieces minimum. Pack weight is listed at 0.23 lbs. Metallics notes other sizes and quantities are available by request.
5) Is the black finish on these screws a corrosion coating, or are they bare?
Bare. The screws are supplied plain in black alloy steel, with no plating or protective coating applied. That means they are for dry interior work, enclosures, panels, and device mounting. In damp or exterior locations use a plated or stainless fastener instead.
6) Will these button head screws meet a spec that calls for ASME B18.3 socket screws?
Yes. The JBSC638 is built to ASME B18.3-2012 for head and socket dimensions, with threads to ANSI/ASME B1.1. Head height of 0.063 to 0.073 inch and head width of 0.25 to 0.262 inch are the figures to check against your drawing.
7) Why pick a button head instead of a standard socket head cap screw?
The button head is low profile, 0.063 to 0.073 inch tall, so it sits nearly flush where a standard socket head would stand proud and catch on conduit, wire, or a panel door. The wider 0.25 to 0.262 inch head spreads bearing load on sheet metal. The trade-off is strength: a full-height socket head cap screw carries more, and these are not recommended for critical, high-strength work.
8) Are these the right screws for electrical panel and device work?
That is what they are intended for. Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries, and 6-32 is the standard machine screw thread for device boxes, cover plates, and enclosure hardware. At 3/8 inch long they suit thin-wall and sheet metal tapped holes rather than deep threaded bosses.
