Metallics JG5HTB54 – Frequently Asked Questions
1) Is the Metallics JG5HTB54 hex tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded, which is what separates it from a standard hex cap screw with a plain shank. The JG5HTB54 is a 5/16-18 x 1-1/4 inch Grade 5 hex tap bolt with right hand threads at 18 threads per inch, built to ASME B18.2.1-2012. Full threading is why these work well where you are running into a tapped hole, such as mounting a motor to machinery.
2) What wrench or socket size do I need for a 5/16-18 Metallics Grade 5 hex tap bolt?
A 1/2 inch wrench or socket. The hex head measures 0.489 to 0.500 inch across the flats, with a head height of 13/64 inch. Wrenching height is 0.14 inch, so you need clean access for the full head depth in tight motor-mount or bracket work.
3) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
Zinc plated steel gives moderate corrosion protection, fine for indoor mechanical rooms, panel work, and sheltered equipment. For direct weather exposure, washdown, or coastal air, go to 18-8 stainless hex tap bolts in the same 5/16-18 size instead. Note the plating also adds no strength; the 105,000 psi minimum tensile comes from the Grade 5 steel itself.
4) How many bolts come in a jar of Metallics JG5HTB54, and can I buy fewer?
They ship as a jar of 100, and 100 count is the order minimum, so the jar is the smallest unit. Total packed weight is 1483 g. Metallics also offers other lengths and pack quantities in the G5HTB and JG5HTB hex tap bolt series by request if 1-1/4 inch is not the grip you need.
5) Do these Metallics hex tap bolts meet Buy American or ARRA requirements on a federal job?
The JG5HTB54 is flagged compliant for both Buy American and ARRA, with country of origin China. On a federally funded project, confirm which clause your contract actually invokes, because the compliance flag and the origin point different ways depending on the provision.
6) What steel are Metallics Grade 5 hex tap bolts made from?
Medium carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties, then zinc plated. That heat treatment is why the hardness lands at Rockwell C19-30 rather than the soft range you get on untreated commercial bolts.
