Metallics JBHC89 – Frequently Asked Questions
1) What thread size and length is the Metallics JBHC89 hex bolt?
It is a 1/2-13 x 3-1/4 inch hex bolt, so 1/2 inch nominal diameter with 13 threads per inch (UNC coarse) and 3-1/4 inches of length under the head. Measured shank outside diameter runs 0.482 to 0.515 inch. Thread form follows ASME B18.2.1-1996, so it mates with any standard 1/2-13 nut or tapped hole.
2) Will the Metallics JBHC89 bolt qualify on a Buy American or ARRA funded job?
No. The JBHC89 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On federally funded work with domestic sourcing requirements, you need a domestically produced fastener instead.
3) What size wrench or socket fits the head on a 1/2-13 Metallics hex bolt?
Head width across flats is 0.725 to 0.750 inch, which is a 3/4 inch wrench or socket. That matches the standard hex head dimension for a 1/2 inch bolt, so it works with normal 3/4 inch impact sockets and open-end wrenches already in the truck.
4) Is this hex bolt plated for corrosion resistance, and can I use it outdoors?
The JBHC89 is steel with a zinc finish. Zinc plating handles dry interior and protected exterior work such as strut, channel, panel and equipment mounting. For direct weather exposure, wet locations, or contact with pressure treated lumber, step up to hot dip galvanized or stainless instead, since the plating on a zinc bolt is thin.
5) How many bolts come in a jar of Metallics JBHC89, and is there a minimum order?
Each jar holds 25 bolts, and 25 pieces is the order minimum. The jar packaging keeps the hardware sorted on a service van or a shop shelf rather than loose in a bin. Other sizes and quantities can be requested.
6) Are nuts and washers included with the Metallics JBHC89 hex bolts?
The jar contains hex bolts only, 25 of them. Order 1/2-13 hex nuts and 1/2 inch flat or lock washers separately to complete the connection.
7) Does a 3-1/4 inch long 1/2-13 bolt come fully threaded or with a plain shank?
Published data for the JBHC89 covers the 1/2-13 thread, the 3-1/4 inch length, the 0.482 to 0.515 inch shank diameter and the hex head dimensions. If your connection depends on an unthreaded grip length through the joint, work from the overall 3-1/4 inch length and the thickness of the material you are clamping, and size the nut and washers to the 1/2-13 thread.
8) Is the JBHC89 the same bolt as the BHC equivalent, just packaged differently?
Both sit in the Metallics BHC and JBHC series of hex bolts. The J prefix on JBHC89 indicates the jar pack, 25 pieces per jar. If you want the same 1/2-13 x 3-1/4 bolt in a different count or a different length, those are available on request.
