Metallics JBHC17PL – Frequently Asked Questions
1) What thread and size are the Metallics JBHC17PL hex bolts?
The JBHC17PL is a 5/16-18 x 3-1/2 inch hex head bolt, so 5/16 inch nominal diameter with 18 threads per inch (coarse UNC) and a 3-1/2 inch length. Measured shank outside diameter runs 0.298 to 0.324 inch. It mates with any standard 5/16-18 nut or tapped hole.
2) Are plain finish steel bolts OK for outdoor or damp electrical installs?
No. These are plain finish carbon steel with no plating or coating, so they will rust in wet, humid, or outdoor locations. Keep them to dry interior work such as strut, panel, and enclosure mounting indoors, and use a zinc plated, hot dip galvanized, or stainless 5/16-18 bolt where moisture is a factor.
3) Do these Metallics hex bolts meet a recognized dimensional standard for government or spec work?
Yes, the hex bolt dimensions conform to ASME B18.2.1-1996, the standard that governs square and hex bolt and screw geometry, so head and thread dimensions are interchangeable with any other B18.2.1 hex bolt of the same size. They are also flagged ARRA compliant and Buy American compliant in the manufacturer data, which matters on federally funded jobs. Country of origin is China.
4) What size wrench or socket fits a 5/16-18 Metallics hex bolt head?
Head width across flats is 0.484 to 0.500 inch, which is a 1/2 inch wrench or socket. Worth knowing before you send a tech up a lift with the wrong roll.
5) How many bolts come in a jar of Metallics JBHC17PL, and can I buy fewer?
They ship as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest buying unit. The jar pack is the point of the JBHC prefix in the Metallics BHC and JBHC bolt line: loose count in a reclosable container rather than a boxed bulk quantity. Metallics does make other sizes and quantities available by request.
6) Will a 3-1/2 inch long 5/16 bolt be long enough for my assembly?
At 3-1/2 inches of total bolt length under the head, you need your combined material stack, plus washers, plus enough thread for the nut to fully engage, to come in under that. For strut and channel work that typically covers a clamp, backing plate, and nut with room left over. If you are through-bolting thicker build-ups, step up in length rather than relying on partial nut engagement.
7) What is the Metallics part number I should order for 5/16-18 x 3-1/2 plain steel hex bolts?
Order Metallics JBHC17PL. The JBHC prefix is the jar packed version of the BHC hex bolt line, and PL designates the plain, unfinished steel.
8) How much does a jar of 100 of these 5/16 x 3-1/2 bolts weigh for shipping or a van stock load?
A full jar of 100 comes in at 8.2 lbs. Useful if you are loading several sizes onto a service van or figuring freight on a multi jar MRO order.
