Metallics JG5HC35 – Frequently Asked Questions
1) Is the JG5HC35 bolt coarse thread or fine thread, and what nut do I need?
It's coarse thread: 1/2-13 means 13 threads per inch, cut to ASME B18.2.1-2012. That pairs with any standard 1/2-13 UNC hex nut or a 1/2-13 tapped hole, such as strut nuts and motor base threads. A 1/2-20 fine thread nut will not run on it.
2) Does this Metallics hex bolt qualify for a Buy American or ARRA funded job?
No. The JG5HC35 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded or Buy America specified project you will need domestically sourced Grade 5 hardware with mill documentation instead.
3) Will a zinc plated steel bolt hold up outdoors or in a damp mechanical room?
The bolt is steel with a zinc finish, which is fine for indoor mechanical rooms, electrical rooms, and general damp-but-sheltered conditions. Zinc plating is a sacrificial coating, not stainless, so for sustained wet exposure, roof curbs, coastal sites, or chemical contact you should be specifying hot dip galvanized or 304/316 stainless hardware instead.
4) What hole size should I drill for a 1/2-13 hex bolt like this?
Shank outside diameter runs 0.4930 to 0.5000 inches, so a 1/2 inch nominal clearance hole is tight. For a bolt-through condition drill 9/16 inch for normal clearance; if you are tapping the hole for 1/2-13 instead, the tap drill is 27/64 inch.
5) Are these hex bolts suitable for electrical and HVAC trade work, or are they automotive only?
They're used across the electrical, plumbing, and heating and air conditioning trades as well as automotive and truck repair. Typical use is mounting a motor to machinery, which also covers fan and blower bases, pump mounts, and equipment anchoring where a 1/2-13 Grade 5 cap screw is called for.
6) What is the material spec on the Metallics G5HC Grade 5 hex bolts?
Steel in the AISI 1008 through 1026 range, heat treated to Grade 5, with 105,000 psi minimum yield and tensile figures and a Rockwell C19-30 hardness. That is the medium carbon range a submittal reviewer expects to see behind a Grade 5 marking.
