Metallics JBHC16PL – Frequently Asked Questions
1) What thread size and length is the Metallics JBHC16PL hex bolt?
It's a 5/16-18 hex bolt, 3 inches long. The 18 threads per inch is the UNC coarse pitch for 5/16 diameter, so it mates with standard 5/16-18 nuts and tapped holes. Thread dimensions follow ASME B18.2.1-1996.
2) Will a plain steel hex bolt hold up outdoors or in a damp electrical room?
No. The JBHC16PL is plain finish steel with no plating or coating, so it will rust in wet, outdoor, or washdown locations. Keep it to dry interior work, and specify a zinc plated or galvanized 5/16-18 x 3 hex bolt for anything exposed to moisture.
3) What wrench or socket size fits these 5/16-18 hex bolts?
Head width across flats measures 0.484 to 0.500 inch, which is a 1/2 inch wrench or socket. Head height runs 0.195 to 0.235 inch and the across-corners width is 0.552 to 0.577 inch, so plan clearance accordingly in tight channel or strut work.
4) What hole size do I need to drill for these bolts?
Shank outside diameter is 0.298 to 0.324 inch, so a 5/16 inch clearance hole is undersized in practice. Drill 11/32 inch for a normal fit, or 3/8 inch where you want adjustment room on a bracket or panel.
5) How many bolts come in a jar and can I buy fewer than 100?
These ship 100 to a jar, and 100 count is the order minimum, so a jar is the smallest buy. Other sizes and quantities are available by request.
6) Do these Metallics hex bolts meet Buy American or ARRA requirements on a federal job?
The JBHC16PL is flagged compliant for both Buy American and ARRA in the manufacturer data, while country of origin is listed as China. On a federally funded project, submit those two data points to your spec reviewer before you commit the material.
7) Does this bolt come with a nut and washers?
No. Model JBHC16PL is bolts only, 100 hex bolts in a jar. Order 5/16-18 hex nuts and any flat or lock washers separately to complete the assembly.
8) Is this a hex cap screw style fastener with a full hex head?
Yes, hex head, no washer face or flange called out beyond the stated head dimensions. It drives with a standard open end, box, or socket wrench rather than any bit, which is what most strut, bracket, and equipment mounting work in an electrical room calls for.
9) What is the shipping weight of a 100 count jar of these 5/16 x 3 bolts?
A full jar runs 7.13 lbs, with the packed carton at 7.25 by 4.5 by 4.5 inches. Worth knowing if you are staging multiple jars on a cart or a service van shelf.
