Metallics JG5HC46 – Frequently Asked Questions
1) Is a 1 inch long 1/2-13 Grade 5 bolt long enough for my application?
The JG5HC46 has a 1 inch shank length, which is short. Add up your clamped material thickness plus washers and allow for the nut to fully engage, and if the total is more than about 1 inch you need a longer bolt. Metallics offers other sizes in the G5HC and JG5HC series by request.
2) Will a 1/2-13 Grade 5 bolt thread into a coarse 1/2 inch nut or tapped hole?
Yes. It is 1/2 inch diameter with 13 threads per inch, which is UNC coarse thread, so it mates with any 1/2-13 coarse nut, coupling, or tapped hole. Measured diameter runs 0.4930 to 0.5000 inch. It will not thread into a 1/2-20 fine-thread hole.
3) Can I use Metallics JG5HC46 Grade 5 hex bolts on a federally funded Buy American job?
No. The JG5HC46 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a job with domestic sourcing requirements you need a documented domestic Grade 5 fastener instead.
4) What wrench size do I need for the Metallics JG5HC46 1/2-13 hex bolt?
Across the flats the hex head measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the size to bring. That matches the standard hex dimensions in ASME B18.2.1-2012 that this bolt is built to.
5) How strong is a Metallics Grade 5 hex cap screw compared to a Grade 2 bolt?
Grade 5 rates 120,000 psi minimum tensile and 92,000 psi minimum yield, with a hardness of Rockwell C25-34. That comes from medium carbon steel that has been heat treated, which is why it holds far more load than an unhardened Grade 2 fastener. For motor mounting and equipment anchoring, Grade 5 is the usual minimum.
6) Is the zinc plating on these Grade 5 hex bolts suitable for outdoor or wet locations?
The finish is zinc on steel, which handles indoor mechanical rooms, equipment rooms, and general MRO work. It gives light corrosion resistance but it is not stainless, so for continuous outdoor exposure, washdown areas, or coastal sites plan on hot dip galvanized or stainless hardware instead.
7) How many bolts come in a jar of Metallics JG5HC46, and can I buy just a few?
It ships as a jar of 50 pieces, and 50 each is the order minimum, so this is a shop-stock quantity rather than a loose-piece purchase. The jar packaging is what makes it practical to keep on a van or a parts shelf.
8) What are these 1/2-13 Grade 5 hex cap screws typically used for?
Mounting motors to machinery is the common one, plus automotive and truck repair. In the trades they get used across electrical, plumbing, and HVAC work, which is where a 1 inch Grade 5 in a jar of 50 earns its shelf space for strut, equipment bases, and bracket work.
9) What steel are Metallics G5HC Grade 5 hex bolts made from?
Steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties and finished in zinc. That medium carbon chemistry is what allows the Rockwell C25-34 hardness; a plain low carbon bolt of the same size would not reach it.
