Metallics JBSC612 6-32 x 1/2 in. Socket Button Head Hex Cap Screws - Alloy Steel Black - Each

The JBSC612 is a 6-32 socket button head cap screw, 1/2 inch long. Threads are 32 per inch in the UN form to ANSI/ASME B1.1, so it mates with any standard 6-32 tapped hole or 6-32 nut. The screw itself is made to ASME B18.3-2012 dimensional standard.

Head height runs 0.063 to 0.073 inch and head width 0.250 to 0.262 inch, so the JBSC612 sits nearly flush and needs about a quarter inch of surface clearance around the hole. That low profile is why button heads get used in enclosures, panels and raceways where a standard socket head would stand too proud. Socket depth for the drive is 0.044 inch.

The JBSC612 is alloy steel with a black finish and the screws are supplied plain, meaning no protective plating is applied. Plain alloy steel will rust in wet or exterior conditions, so keep these to dry interior work, panels and enclosures. For damp, exterior or washdown locations choose a stainless or zinc plated 6-32 screw.

No. The JBSC612 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your job carries a domestic sourcing requirement, these will not satisfy it and you need a domestically manufactured 6-32 button head instead.

It is a socket head with a hex drive, so you need an Allen key or hex bit, not a screwdriver. The socket is 0.044 inch deep, so seat the bit fully before applying torque to avoid rounding the recess.

They come 100 to a jar, and the jar is the minimum order unit. So the smallest purchase is 100 pieces, packed weight 0.26 lbs. That suits a service van or an MRO crib where you want one container of 6-32 button heads on the shelf rather than loose counts.

Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. In practice a 6-32 x 1/2 inch button head goes into device and cover plate mounting, enclosure and panel covers, control boxes and equipment brackets, anywhere a low-profile head is wanted and the joint is not load critical.

Not in the strict sense. The Metallics BSC spec notes that screws must be at least 3 diameters long to be subject to tensile testing, and elongation figures apply to machined specimens of at least 4D. A 6-32 at 1/2 inch is short relative to its diameter, so judge it on the stated 1260 lb minimum tensile value and treat it as a general fastening screw rather than a tested high-strength one.
