Metallics JG5HC84 – Frequently Asked Questions
1) What thread and size is the Metallics JG5HC84 hex bolt, and will a standard 3/4-10 nut fit it?
The JG5HC84 is a 3/4-10 by 4 inch hex cap screw, meaning 10 threads per inch on a 3/4 inch nominal diameter. That is the UNC coarse pitch for 3/4 inch, so any standard 3/4-10 coarse nut or tapped hole will take it. Measured shank outside diameter runs 0.7410 to 0.7500 inch, and threads are made to ASME B18.2.1-2012.
2) What size wrench or socket do I need for a 3/4-10 Grade 5 hex bolt?
Across the flats the hex head measures 1.100 to 1.125 inch, so a 1-1/8 inch socket or wrench is the fit. Head height is 15/32 inch, with a wrenching height of 0.324 inch, so a standard depth socket seats fully on the head.
3) How much grip length do I actually get on a 4 inch long 3/4-10 hex bolt?
Length on a hex cap screw is measured from under the head to the tip, so the 4 inch figure is your usable reach through the joint, not including the 15/32 inch head. Size your stack so the bolt passes the material plus washers and leaves a couple of threads past the nut. If 4 inches leaves you short or long, Metallics offers other lengths in the G5HC and JG5HC series.
4) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The finish is zinc plating over steel, which handles indoor and sheltered service and resists handling corrosion in a damp plant or mechanical room. It is not a marine or continuously wet finish; for direct weather exposure, splash, or chemical contact, specify hot dip galvanized or stainless instead.
5) How many bolts come in a jar of Metallics JG5HC84, and is 10 the minimum I can buy?
JG5HC84 ships as a jar of 10 bolts, and 10 count is the order minimum. The jar pack is the reason for the J prefix; the same Grade 5 hex cap screw is catalogued under the G5HC and JG5HC series if you want a different pack or size. Jar weight is 1188 g.
6) Does the JG5HC84 hex bolt meet Buy American or ARRA requirements on a federal job?
Metallics flags the JG5HC84 as ARRA compliant and Buy American compliant, with country of origin China. On a federally funded project, run both of those against the specific clause in your contract, since Buy American and Build America Buy America provisions treat fasteners differently from job to job.
7) What steel is this Grade 5 hex bolt made from?
Medium carbon steel in the AISI 1008 to 1026 range, heat treated to Grade 5 properties and finished in zinc. That puts hardness at Rockwell C19-30. It is a carbon steel fastener, so do not use it where a corrosion resistant alloy or a non magnetic fastener is specified.
