Metallics JG5HC81 – Frequently Asked Questions
1) How strong is a grade 5 hex bolt and is it strong enough for mounting a motor?
Grade 5 medium carbon steel, heat treated: 120,000 psi minimum tensile and 92,000 psi minimum yield, with hardness in the Rockwell C25-34 range. That's the common structural-duty cap screw class used for mounting motors to machinery and for automotive and truck repair. If an engineer has specified grade 8, this is not a substitute.
2) Do these Metallics bolts meet Buy American or ARRA requirements for a public project?
No. The JG5HC81 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. On a federally funded job with domestic sourcing language, you'll need a domestic grade 5 hex bolt instead.
3) How many bolts come in a jar of Metallics JG5HC81?
They ship 50 pieces in a jar, and 50 each is the minimum order. The jar packaging keeps a single size together on the truck or the shop bench rather than loose in a bin, which is why MRO and service stock buyers use it.
4) What material is a Metallics grade 5 hex cap screw made from?
Medium carbon steel, heat treated, to material standard AISI 1008-1026, with a zinc finish. The heat treat is what takes it to grade 5 property class rather than a plain low carbon bolt.
5) Can I get this grade 5 hex bolt in other lengths or pack sizes?
Yes. The G5HC and JG5HC series runs other sizes and quantities by request; the JG5HC81 is the 1/2-13 x 3/4 jar of 50 within that family.
