Metallics JG8HC25 – Frequently Asked Questions

1) Is the Metallics JG8HC25 hex bolt a coarse thread 3/8 bolt?
Yes. The JG8HC25 is a 3/8-16 bolt, so 16 threads per inch, which is the standard coarse pitch for 3/8 diameter. Shank outside diameter runs 0.3690 to 0.3750 inch, so it drops through a standard 3/8 clearance hole and takes any 3/8-16 coarse nut or tapped hole.
2) What is the difference between a Grade 8 hex bolt and a Grade 5 for strength?
Grade 8 is the higher strength option. The Metallics JG8HC25 is Grade 8 with 150,000 psi minimum tensile and 130,000 psi minimum yield, hardness Rockwell C33-39. It is a medium carbon steel cap screw, heat treated, used where greater tensile strength is required than a Grade 5 can meet. If your load calc or drawing only calls for Grade 5, a Grade 5 fastener is adequate; go Grade 8 where the spec demands it or where the joint sees high clamp load and vibration.
3) Is the Metallics JG8HC25 bolt Buy American or ARRA compliant for a government job?
No. The JG8HC25 is not Buy American compliant and is not ARRA compliant. Country of origin is listed as multiple. If your project carries a domestic sourcing requirement, this bolt will not satisfy it.
4) Will the zinc plating on this bolt hold up outdoors?
The JG8HC25 is steel with a zinc finish. Zinc plating is a general-purpose corrosion coating suited to indoor and protected applications, including the electrical, plumbing, and HVAC work this bolt is catalogued for. For continuous exposure, salt spray, or wet locations, specify hot dip galvanized or stainless instead.
5) How many bolts come in a jar of Metallics JG8HC25?
They ship 50 pieces to a jar, and 50 each is the order minimum. The filled jar weighs 1982 g.
6) What steel is used in this Grade 8 cap screw?
Medium carbon steel in the AISI 1021 to 1045 range, heat treated to Rockwell C33-39. That heat treatment is what gets it to the Grade 8 strength numbers, and it is also why these should not be welded or re-heated in the field.
7) Can I get this 3/8-16 Grade 8 bolt in a different length or a larger pack?
The JG8HC25 is the 3/8-16 x 2-1/2 inch size in a 50 piece jar. Metallics builds the same Grade 8 zinc plated hex bolt across the G8HC and JG8HC series in other sizes and quantities by request, so if you need a shorter grip length or a bulk box rather than a jar, ask for the series equivalent.
