Metallics JG5HTB1 – Frequently Asked Questions
1) What thread does the Metallics JG5HTB1 hex tap bolt use, and will it go into a standard 1/4-20 tapped hole?
It is a 1/4-20 bolt: 20 threads per inch, right-hand thread, cut to ASME B18.2.1-2012. Shank outside diameter runs 0.2450 to 0.2500 inch, so it drops into any standard 1/4-20 tapped hole or mates with a standard 1/4-20 nut. Being a tap bolt, it is threaded the full length rather than having a plain shoulder.
2) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
Yes, that is the usual application for these. Grade 5 medium carbon steel, heat treated, with 120,000 psi minimum tensile and 92,000 psi minimum yield, and hardness of Rockwell C25-34. That covers motor mounting, machinery brackets, and automotive or truck repair work. If your drawing calls out Grade 8 or a stainless fastener, this is not a substitute.
3) What wrench or socket size fits the head on this 1/4-20 Metallics hex tap bolt?
Head width across flats measures 0.428 to 0.438 inch, which is a 7/16 inch wrench or socket. Head type is a standard hex, with 0.106 inch of wrenching height on the flats.
4) Will the zinc finish on these steel bolts hold up outdoors or in a damp mechanical room?
The bolt is steel with a zinc plating, which handles indoor and damp mechanical room service and gives light outdoor protection. For continuous weather exposure, washdown, or coastal work, step up to a stainless or hot dip galvanized fastener instead; zinc plate is a thin sacrificial coating, not a marine finish.
5) How many bolts come in a jar, and can I buy fewer than 100?
These ship as a jar of 100, and 100 count is the order minimum, so it is sold by the full jar rather than loose by the piece. Other sizes and quantities in the G5HTB and JG5HTB range can be had by request.
6) Do these Metallics hex tap bolts qualify for a Buy American or ARRA funded job?
The record flags both ARRA compliant and Buy American compliant, with country of origin China. On a federally funded project where the specification requires domestically melted and manufactured fasteners, confirm which standard your contract is written to before committing these.
7) What steel is used in the Metallics G5HTB hex tap bolt?
Medium carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties. That is what gets it to Rockwell C25-34 and the 120,000 psi tensile minimum, and it is why the bolt should not be welded or re-heated after the fact, which undoes the heat treatment.
8) What is the exact part number to reorder these Metallics Grade 5 hex tap bolts?
Order Metallics JG5HTB1, the 1/4-20 x 3/4 Grade 5 zinc hex tap bolt in a 100 count jar. The J prefix marks the jar pack; the same bolt in the plain G5HTB series numbering is the bulk equivalent.
