Metallics JBSC61 6-32 x 1 in. Socket Button Head Hex Cap Screws - Alloy Steel Black - Each

The JBSC61 is a 6-32 screw, 1 inch long, with 32 threads per inch on a UN thread form cut to ANSI/ASME B1.1. So it mates with any standard 6-32 tapped hole or 6-32 nut. Head dimensions run 0.25 to 0.262 in. across and 0.063 to 0.073 in. high, with the overall screw dimensioned to ASME B18.3-2012.

1,260 lb minimum tensile is the rated figure on the JBSC61, with the alloy steel heat treated to Rockwell C39-44. That said, the manufacturer states button head socket screws are not recommended for critical, high-strength applications. If you are fastening a structural or safety-critical connection, use a socket head cap screw with a full-height cylindrical head instead.

Hex key, not a screwdriver. The JBSC61 has a socket button head with a hex drive recess, and the socket depth is 0.044 in. There is no slot or Phillips on it, so an electrician or installer needs an Allen wrench or hex bit on hand.

No. The JBSC61 is alloy steel black and the screws are supplied plain, meaning the black is the mill/oxide condition rather than a plated or protective coating. Treat them as indoor or dry-location hardware; for wet or exterior work, specify a plated or stainless fastener.

They ship as a 100-count jar, and 100 is the order minimum. That is the packaged unit, so you are buying the jar rather than loose pieces. The packed jar weighs 0.46 lbs.

The JBSC61 carries both an ARRA compliant and a Buy American compliant flag in the manufacturer data, with country of origin listed as China. On a federally funded project where the compliance flag and the origin need to line up with your contract language, confirm which clause your spec is written to before you submit them.

No. A button head sits proud of the surface on a rounded dome, it does not draw into a countersink. The JBSC61 head is 0.063 to 0.073 in. high and 0.25 to 0.262 in. across, so plan on about that much protrusion above the panel or enclosure face. For a flush finish you need a flat head socket screw instead.

Yes. The tensile testing rule on these is that a screw must be at least 3 diameters long to be subject to tensile testing, and at 1 inch the 6-32 JBSC61 is well past that. The 8 percent elongation minimum applies to machined specimens at least 4D long, with 35 percent reduction of area minimum on machined specimens.

The JBSC61 itself is fixed at 6-32 x 1 in. in the black alloy steel BSC series, but Metallics offers other sizes and quantities in this button head socket line by request. If you are standardizing a panel build or an MRO bin on one drive type, that is the route to a matched set of lengths.
