Metallics G5HC38 – Frequently Asked Questions
1) What thread and diameter is the Metallics G5HC38 hex bolt, and what wrench size does it take?
It's a 1/2-13 bolt: nominal 1/2 inch diameter with 13 threads per inch, which is standard UNC coarse thread. Measured shank outside diameter runs 0.4930 to 0.5000 inch. Across the flats the hex head measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket fits it. Overall length is 5 inches.
2) How strong is a Grade 5 hex bolt, and is it strong enough for mounting a motor?
Grade 5 here means medium carbon steel, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Motor mounting to machinery is exactly what it's commonly used for, along with automotive and truck repair. If an engineer's drawing calls out Grade 8, this is not a substitute, Grade 5 is a lower strength class.
3) Do these Metallics hex bolts qualify for a Buy American or ARRA funded project?
No. The G5HC38 hex bolt is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a federally funded job with domestic sourcing requirements you'll need a domestic Grade 5 hex bolt instead.
4) How many bolts come in a box of Metallics G5HC38, and can I buy just a few?
They ship as a box of 25, and 25 each is the order minimum, so that box is the smallest purchase. Other sizes and quantities are available by request.
5) Can these zinc plated Grade 5 bolts be used outdoors or in a wet location?
The bolt is steel with a zinc finish, which gives moderate corrosion protection for dry indoor and sheltered use. Zinc plating is not marine or chemical grade protection, so for standing water, coastal exposure, or washdown areas use stainless or hot dip galvanized hardware instead.
6) What steel is used in these Grade 5 bolts, and will they weld or re-tap well?
Material standard is AISI 1008 through 1026, a medium carbon steel that is then heat treated to reach Grade 5 strength. Because the strength comes from heat treatment, welding or heating the bolt will soften it and drop it below its 105,000 psi rating. Drill or cut only where strength is not in play.
