Metallics JBSC5161 – Frequently Asked Questions

1) Will a 5/16-18 button head cap screw fit into a counterbore made for a standard socket head cap screw?
Probably not on depth. The button head on the JBSC5161 measures 0.527 to 0.547 in. across the head with a head height of only 0.152 to 0.166 in., so it is wider and much shallower than a standard hex socket head cap screw of the same 5/16-18 diameter. It sits almost flush in a shallow pocket but will not drop into a deep narrow counterbore cut for a standard socket head. Check your clearance hole against those two numbers before ordering.
2) Will these screws thread into an existing 5/16-18 tapped hole or nut?
Yes. The JBSC5161 is 5/16-18 with 18 threads per inch, a UN thread form made to ANSI/ASME B1.1, so it mates with any standard 5/16-18 coarse tapped hole or nut. Overall length is 1 in., which sets your usable thread engagement once the head is seated.
3) Are these black alloy steel screws okay for outdoor or damp locations?
Keep them indoors or in dry locations. The JBSC5161 is alloy steel with a black finish and is supplied plain, meaning no protective plating or coating, so it will corrode in wet, exterior, or washdown environments. For outdoor enclosures, rooftop equipment, or anywhere subject to moisture, use a plated or stainless fastener instead.
4) Will these screws satisfy a Buy American or ARRA requirement on a public project?
No. The JBSC5161 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded or domestic-preference job, these will not pass submittal, so source a domestically produced fastener for that work.
5) What size hex key do I need to drive a Metallics JBSC5161 button head socket cap screw?
The JBSC5161 takes a hex (Allen) key, not a screwdriver or wrench flats. The socket depth in the head is 0.105 in., so a standard short-arm hex key seats fully. Drive type is hex and the head is a socket button style, so plan on an Allen set or hex bit on the truck rather than a nut driver.
6) Do Metallics JBSC5161 screws come loose or do I have to buy a full box?
They ship in a jar, with a 100-piece minimum order quantity. So the buying unit is a 100-count jar rather than individual screws, which suits an MRO crib or a shop drawer where 5/16-18 is a repeat consumable.
7) What dimensional standard do these 5/16-18 socket button head cap screws meet?
Head and body dimensions follow ASME B18.3-2012, the standard for socket cap screws, and the threads follow ANSI/ASME B1.1. If your drawing calls out B18.3 button head socket cap screws in 5/16-18 x 1 in., the JBSC5161 matches that callout dimensionally.
8) What are these button head cap screws typically used for in the trades?
Metallics lists the JBSC5161 for electrical, plumbing, heating and air conditioning work. In practice that is equipment panels, brackets, strut and channel assemblies, and cover plates where the low rounded head is less likely to snag than a standard hex socket head. It is a general-purpose assembly screw, not a structural one.
