Metallics JBHC48 Bolts 1/4-20 X 5/8 Hxbt St-zn (Jar 100)

Yes. The JBHC48 is a 1/4-20 hex bolt, 20 threads per inch on a 1/4 inch nominal diameter, made to ASME B18.2.1-1996. Measured shank outside diameter runs 0.237 to 0.260 inch, so it mates with any standard 1/4-20 nut, channel nut, or tapped hole in Unified coarse thread.

For conduit straps, strut clamps, box mounting, and general hanger work, yes. The JBHC48 is Grade 2 steel with a zinc plating, which is the normal spec for electrical, plumbing, and HVAC support hardware. Grade 2 is low carbon, unhardened, so it is not the right bolt for a structural connection or a high-torque, high-tension joint. Those call for Grade 5 or Grade 8.

No. These hex bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements you will need to specify a domestically produced 1/4-20 hex bolt instead.

Zinc plating on these steel hex bolts is a mild corrosion coating meant for dry indoor and protected service. In rooftop, wash-down, coastal, or buried conditions the plating will give up and the steel will rust. For those openings specify hot dip galvanized or stainless 1/4-20 hardware instead.

They ship as a jar of 100 pieces, and 100 is the order minimum, one jar being the minimum unit. No partial counts. The jar packaging is handy on a van or a cart because it keeps the 5/8 inch bolts together instead of loose in a bin. Metallics notes other sizes and quantities in the BHC and JBHC series are available by request.

No. The jar holds hex bolts only, 100 of them. You will need to order 1/4-20 hex nuts and any flat or lock washers separately to complete the joint.

A full jar comes in at 1.32 lbs, with the jar itself about 3 inches across and 2.7 inches tall. Light enough that a few jars of different lengths in the BHC and JBHC series can ride together in one bin without eating payload.
