Metallics JBHC5 – Frequently Asked Questions
1) What grade steel are these 1/4-20 hex bolts, and is that strong enough for hanging strut and conduit racks?
Grade 2 steel, zinc plated. Grade 2 is the general-purpose low-carbon grade, which is what most electrical and mechanical trades use for strut, trapeze hangers, box and enclosure mounting, and similar non-structural support work. If your drawing calls out a Grade 5 or Grade 8 bolt for a high-tension or structural connection, this is not the bolt for it.
2) How many bolts come in a jar of Metallics JBHC5, and can I buy fewer?
They ship as a jar of 100 bolts, and the jar is the order minimum, so 100 pieces is the smallest quantity. Metallics also offers other sizes and quantities of this hex bolt by request.
3) Are Metallics JBHC5 bolts Buy American or ARRA compliant for a government job?
No. The JBHC5 hex bolt is not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your federal, state, or institutional contract carries a domestic sourcing clause, this bolt will not satisfy it.
4) Will zinc plated hex bolts hold up outdoors or in a damp mechanical room?
The zinc plating on these steel bolts gives moderate corrosion resistance, which is fine for indoor mechanical rooms, ceiling spaces, and damp but sheltered locations. For direct weather exposure, wet locations, or corrosive environments, step up to hot dip galvanized or stainless fasteners instead.
5) What size wrench or socket fits the head on these 1/4-20 hex bolts?
Head width across flats measures 0.425 to 0.438 inches, which is the standard 7/16 inch hex for a 1/4 inch bolt, so a 7/16 socket or wrench drives it. Width across corners runs 0.484 to 0.505 inches, worth checking if you are driving it inside a tight strut channel or a crowded box.
6) What is the actual shank diameter on a 1/4-20 bolt, and what clearance hole should I drill?
Measured outside diameter is 0.237 to 0.260 inches. A 1/4 inch hole is a tight fit at the top of that range, so drill 9/32 or 5/16 for a normal clearance hole and the bolt will pass without forcing.
7) What trades and applications are these Metallics hex bolts intended for?
Metallics lists the BHC and JBHC hex bolts for the electrical, plumbing, and heating and air conditioning industries, which is why they come jarred in 100 counts for van stock and MRO shelves rather than bulk boxed. Typical use is enclosure and panel mounting, strut and hanger assembly, and general fixture support.
8) How much does a jar of 100 of these 1/4-20 x 2-1/2 hex bolts weigh?
A jar of 100 comes in at 3.86 lbs, useful if you are loading out a service van or figuring freight on a multi-jar order.
