Metallics JBHC29 – Frequently Asked Questions

1) What size and thread is the Metallics JBHC29 hex bolt?
It's a 3/8-16 x 4-1/2 inch hex bolt. The 16 threads per inch is standard UNC coarse thread for 3/8 inch diameter, so it takes any standard 3/8-16 nut, coupling nut, or tapped 3/8-16 hole. Measured shank outside diameter runs 0.360 to 0.388 inch, and the hex head measures 0.544 to 0.562 inch across the flats, which a 9/16 inch wrench or socket drives.
2) Is a Grade 2 zinc plated bolt strong enough for hanging electrical and HVAC supports?
The JBHC29 is a Grade 2 steel bolt with a zinc finish, which is the common general-purpose strength class for electrical, plumbing, heating and air conditioning work: strut and channel connections, box and fixture mounting, hanger and bracket assembly. If your drawing calls out Grade 5 or Grade 8, or a structural connection, this is not the bolt to substitute in. For wet or outdoor exposure, zinc plating is a mild corrosion coating only, not hot dip galvanized or stainless.
3) Are Metallics JBHC29 bolts Buy American or ARRA compliant for a government job?
No on both counts. The JBHC29 hex bolt is not Buy American compliant and not ARRA compliant, and country of origin is listed as multiple. If your federal, state, or institutional contract carries a domestic-content requirement on fasteners, this bolt will not satisfy it.
4) How many bolts come in a jar of Metallics JBHC29, and can I buy fewer?
They ship in a jar of 50 pieces, and 50 each is the order minimum, so the jar is the smallest unit. Metallics also builds the BHC and JBHC hex bolt series in other sizes and pack quantities on request if 50 of this length isn't what the job needs.
5) Does the Metallics JBHC29 hex bolt meet ASME B18.2.1?
Yes. The thread and head dimensions are built to ASME B18.2.1-1996, the hex bolt and screw dimensional standard, which is why the head measures within 0.544 to 0.562 inch across the flats and the shank within 0.360 to 0.388 inch. That makes it dimensionally interchangeable with any other B18.2.1 3/8-16 hex bolt already in your facility, so you can standardize on it across trades.
6) Do nuts and washers come with these hex bolts?
No. A jar of 50 contains hex bolts only, so order 3/8-16 hex nuts and 3/8 flat or lock washers separately to complete the connection. Match the plating, zinc on zinc, so you don't set up galvanic corrosion between the bolt and the nut.
7) How much does a jar of 50 Metallics 3/8 x 4-1/2 hex bolts weigh?
About 7.23 lbs for the packed jar. Worth knowing if you're staging material by floor or filling out a parcel shipment, since a few jars add up fast on a cart.
