Metallics JG5HC73 – Frequently Asked Questions
1) Is a Grade 5 bolt strong enough for mounting a motor, or do I need Grade 8?
Grade 5 is the normal choice for motor and equipment mounting, and that is exactly the stated use for this bolt. It is medium carbon steel, heat treated, with 105,000 psi minimum tensile and a hardness of Rockwell C19-30. Step up to Grade 8 only where the engineering drawing calls for it or you are dealing with high shock and fatigue loading; otherwise Grade 5 at 5/8-11 carries heavy machinery feet without trouble.
2) Do these Metallics Grade 5 hex bolts meet Buy American or ARRA requirements for a public job?
No. They are not Buy American compliant and not ARRA compliant, and country of origin is listed as multiple. On a federally funded or Buy America specified project you will need a domestic Grade 5 fastener instead.
3) Will the zinc finish on these bolts hold up outdoors or in a damp mechanical room?
The plating is zinc (zinc chromate), which is a mild corrosion barrier meant for indoor and sheltered use, the electrical, plumbing and HVAC work it is catalogued for. It handles a damp mechanical room or a rooftop curb reasonably, but direct weather exposure, coastal air, or treated lumber contact will eat through it. For those, specify hot dip galvanized or stainless instead.
4) Do nuts and washers come with the Metallics JG5HC73 hex bolts?
No. The jar contains 25 bolts only. Order 5/8-11 hex nuts and 5/8 flat and lock washers separately to complete the assembly.
5) Can I use a 5/8-11 Grade 5 hex bolt for truck or automotive repair work?
Yes, that is a stated use alongside mounting motors to machinery. It is a heat treated medium carbon steel cap screw at 105,000 psi minimum tensile, which covers typical chassis, bracket and equipment fastening. For suspension or other high stress automotive points where the manufacturer specifies a higher grade or a metric fastener, match the original spec rather than substituting this.
