Metallics JG9HC15 – Frequently Asked Questions
1) Is a Grade 9 bolt stronger than the Grade 5 or Grade 8 bolts I normally use?
Yes. Grade 9 sits above Grade 8 in the SAE strength ladder, which in turn sits above Grade 5, so the JG9HC15 is the high-strength end of the hex cap screw range. If a drawing calls for Grade 5 or Grade 8 in 3/8-16 x 1-3/4, a Grade 9 meets or exceeds that strength requirement, though if your spec is written as an exact grade match rather than a minimum, order the grade on the print.
2) Will the Metallics JG9HC15 work in a 3/8 inch hole, or do I need to drill larger?
A 3/8-16 hex cap screw needs clearance above its 3/8 inch nominal diameter to pass through a plain hole, so a hole drilled at exactly 3/8 will bind. Standard clearance for a 3/8 fastener is 7/16 inch. If instead you are threading it into tapped steel or a tapped channel insert, the tap must be 3/8-16 to match the thread.
3) Does the Metallics JG9HC15 come with nuts and washers?
No. The JG9HC15 is bolts only, 25 per jar. Order 3/8-16 nuts and 3/8 flat or lock washers separately, and match the nut grade to the bolt so the joint is not limited by the nut.
4) Is a hex cap screw the right fastener for strut and electrical equipment mounting, or should I use a different head?
A hex cap screw like the JG9HC15 is the usual choice where you need real torque into a tapped hole or a nut, which covers equipment frames, transformer and panel mounting, and strut connections made up with channel nuts. Where you need the head to sit flush or to slide inside a channel, a square head or carriage bolt is the better fit instead, and for sheet metal enclosures a machine screw is the normal answer rather than a cap screw.
5) What size wrench or socket do I need for this 3/8-16 hex cap bolt?
A 3/8-16 hex cap screw takes a 9/16 inch wrench or socket across the flats, which is the standard hex head size for that diameter. Nothing special is needed beyond a normal combination wrench or impact socket.
