Metallics JG8HC76114 – Frequently Asked Questions
1) Is the Metallics JG8HC76114 a coarse thread bolt, and what wrench size does the head take?
Thread is 7/16-14, so 14 threads per inch, which is the coarse (UNC) pitch for 7/16 diameter. The hex head measures 0.612 to 0.625 inch across the flats, so it drives with a 5/8 inch wrench or socket. Head height is 19/64 inch and the shank outside diameter runs 0.4305 to 0.4375 inch.
2) How strong is a Grade 8 hex cap screw compared to a Grade 5?
The Grade 8 bolt is rated 150,000 psi minimum tensile and 130,000 psi minimum yield, with a hardness of Rockwell C33-39. It is medium carbon steel, heat treated, and it is the one to reach for when a Grade 5 does not carry the load, which is why these get used in automotive and fleet work.
3) Does the Metallics Grade 8 hex bolt qualify for a Buy American or ARRA funded project?
No. The JG8HC76114 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On federally funded work with domestic sourcing requirements, you will need a domestically produced fastener instead.
4) What steel and coating is the Metallics G8HC series hex bolt made from, and will it hold up outdoors?
Steel per AISI 1021 to 1045 with a zinc finish. Zinc plating is a light corrosion barrier meant for dry or sheltered conditions, not sustained weather or wet exposure. For an exposed or corrosive location, specify a hot dip galvanized or stainless fastener instead.
5) How many bolts come in a jar of Metallics JG8HC76114, and is there an order minimum?
They ship in a jar of 25. Packaging type is jar, and the imperial order minimum is 100 jars. Other sizes and quantities are available by request.
6) What grip length do I get with a 1-1/4 inch Grade 8 hex bolt, and will it work for strut or channel work?
The JG8HC76114 is a 7/16-14 by 1-1/4 inch hex cap screw, a short bolt suited to clamping thin assemblies where only a limited grip is needed. Metallics lists it for electrical, plumbing, heating and air conditioning work. If your stack-up plus nut and washers exceeds 1-1/4 inches, step up to a longer length in the same series rather than running short threads.
7) What nut should I pair with a 7/16-14 Grade 8 bolt?
Match the thread exactly: a 7/16-14 coarse thread nut. To get the full rated strength of a 150,000 psi minimum tensile bolt, use a Grade 8 (or equivalent hardened) nut rather than a standard Grade 2 nut, and keep the finish consistent with the bolt's zinc plating to avoid mixing dissimilar coatings.
