Metallics JG8HC35 – Frequently Asked Questions

1) What thread size and length is the Metallics JG8HC35 hex bolt?
It is a 1/2-13 by 3 inch hex cap screw, so 1/2 inch diameter with 13 threads per inch (UNC coarse) and a 3 inch length under the head. That means it mates with any standard 1/2-13 nut or tapped hole.
2) Can I use these Grade 8 bolts on a federally funded or Buy American job?
No. The Metallics JG8HC35 is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. For a project with domestic sourcing requirements you will need a domestically produced Grade 8 bolt instead.
3) How many bolts come in a jar of Metallics JG8HC35, and can I buy less than a full jar?
The bolts ship 25 to a jar, and 25 each is the order minimum, so the jar is the smallest buying unit. Metallics notes that other sizes and quantities in the G8HC and JG8HC series are available by request.
4) Will zinc plated Grade 8 bolts hold up outdoors or in a damp mechanical room?
The bolt is medium carbon steel with a zinc plated finish, which handles indoor and sheltered mechanical rooms fine and gives moderate protection in damp conditions. It is not stainless, so for direct weather exposure, roof curbs, or coastal and wash-down areas you will get longer life from stainless or hot dip galvanized hardware. Note that Grade 8 strength levels are not available in standard 18-8 stainless, so a stainless swap trades strength for corrosion resistance.
5) What material and hardness does the Metallics Grade 8 hex bolt meet?
Medium carbon steel in the AISI 1021 to 1045 range, quenched and tempered to Rockwell C33-39. That hardness is what gets it to the Grade 8 strength numbers, and it is also why these bolts should not be welded, bent, or re-heated in the field; heat ruins the temper and drops the rating.
6) What nuts and washers do I need to order with the 1/2-13 x 3 Grade 8 bolts?
The jar contains bolts only, no nuts or washers. For a Grade 8 assembly match it with 1/2-13 Grade C (Grade 8 equivalent) hex nuts and hardened flat washers; a standard Grade 2 nut or an unhardened washer becomes the weak link and the washer will dish under a Grade 8 bolt's clamp load. Also check your grip: a 3 inch length needs enough thread engagement past the nut, so measure total material thickness plus washer stack before you size it.
7) Are Metallics G8 hex bolts meant for electrical and mechanical trade work or just automotive?
Both. Metallics lists the field application as electrical, plumbing, heating and air conditioning work, and the G8 line is also used in automotive and fleet service where Grade 5 strength falls short. For an electrician or HVAC contractor it is the bolt to reach for on heavy equipment anchoring, hanger assemblies, and structural attachments carrying real tension load.
