Metallics JG5HC3 – Frequently Asked Questions
1) Will a 1/4-20 Grade 5 hex bolt thread into a standard 1/4-20 nut or tapped strut channel?
Yes. The JG5HC3 is cut 20 threads per inch on a 1/4 in. diameter, with shank diameter held to 0.2450 to 0.2500 in., and threads made to ASME B18.2.1-2012. Any 1/4-20 UNC nut, tapped hole, or channel nut will take it.
2) How strong is a Grade 5 hex bolt compared to a plain hardware-store bolt?
Grade 5 means the bolt is medium carbon steel that has been heat treated, and the JG5HC3 is rated 105,000 psi minimum tensile and 105,000 psi minimum yield, with a hardness of Rockwell C19-30. An ungraded (Grade 2) bolt with a blank head is substantially softer and is not a substitute where a drawing calls for Grade 5. Grade 5 bolts carry three radial lines on the head.
3) Does this Metallics hex bolt meet Buy American or ARRA requirements on a federal or public job?
No. The JG5HC3 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic sourcing clause, this part will not satisfy it and you need a domestic Grade 5 hex bolt instead.
4) What wrench or socket size fits the Metallics JG5HC3 1/4-20 hex bolt?
Head width across flats on the JG5HC3 measures 0.428 to 0.438 in., so a 7/16 in. wrench or socket is the right tool. That is the standard across-flats size for a 1/4 in. hex cap screw.
5) Is a zinc plated steel bolt OK for outdoor or damp mechanical room use?
The JG5HC3 is steel with a zinc finish, which handles indoor mechanical rooms, equipment mounting, and sheltered outdoor use. For sustained wet exposure, salt spray, or coastal work, step up to hot dip galvanized or stainless; zinc plating is a light sacrificial coating, not a marine finish.
6) How many bolts come in a jar of Metallics JG5HC3?
These ship 100 pieces to a jar, and the jar is the order minimum. The jar pack keeps a single size separated on the truck or in a gang box rather than mixed loose in a bin.
7) What is this 1/4-20 x 1-1/2 Grade 5 bolt normally used for?
It is a cap screw used for mounting motors to machinery and is common in automotive and truck repair, as well as electrical, plumbing, and HVAC work. Typical trade uses are equipment and motor mounting, hanger and bracket attachment, and anywhere a tapped hole or nut takes a 1/4-20 fastener with real clamp load behind it.
8) Can I get this Grade 5 hex bolt in other lengths or diameters?
Yes. Metallics builds the G5HC and JG5HC series across other sizes and pack quantities, available by request, so you can standardize one grade and finish across a range of lengths for a job.
9) What steel is the Metallics Grade 5 hex bolt made from?
Material is carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties, finished in zinc. That is the standard medium carbon spec behind a 105,000 psi minimum Grade 5 cap screw.
