Metallics JG5HC13 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC13 hex bolt, and what nut will it take?
It's a 5/16-18 hex cap screw, so 18 threads per inch in the coarse (UNC) series. Shank outside diameter runs 0.3065 to 0.3125 in. Pair it with a 5/16-18 UNC hex nut; a 5/16-24 fine-thread nut will not thread on.
2) Do these Metallics hex bolts meet Buy American or ARRA requirements for a government job?
No. The JG5HC13 Grade 5 hex bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, you'll need a domestically produced Grade 5 hex cap screw instead.
3) Can I use these zinc plated Grade 5 bolts outdoors or on rooftop HVAC equipment?
The bolts are steel with a zinc finish, which gives moderate corrosion resistance for covered or indoor use and light exterior exposure. For constant weather, coastal salt air, or wet mechanical rooms, go to hot dip galvanized or stainless fasteners instead. Metallics lists these for electrical, plumbing, and heating and air conditioning work.
4) How many bolts come in a jar of Metallics JG5HC13 and can I buy fewer?
They ship in a jar of 100, and 100 is the order minimum, so it's sold by the full jar rather than by the piece. Metallics does offer other sizes and quantities in the G5HC and JG5HC series by request.
5) What dimensional standard do these hex cap screws follow, and will they interchange with other brands?
Threads and head dimensions follow ASME B18.2.1-2012, the standard for hex bolts and hex cap screws, and the steel is AISI 1008-1026. Any other 5/16-18 x 1-1/2 Grade 5 hex cap screw built to that same standard will drop into the same hole and take the same 1/2 in. wrench.
6) Is the JG5HC13 a bolt or a cap screw, and does it come with a nut or washer?
It's a hex cap screw, hex head, sold as the fastener only. No nuts, flat washers, or lock washers are included, so order 5/16-18 nuts and 5/16 washers separately if the connection isn't a tapped hole.
