Metallics JG5HTB104 – Frequently Asked Questions
1) What thread does the Metallics JG5HTB104 hex tap bolt use, and will it thread into a standard 3/8-16 tapped hole?
It's a 3/8-16 right-hand thread, 16 threads per inch, cut to ASME B18.2.1-2012. Threading runs full length on a hex tap bolt, so it will engage a tapped 3/8-16 hole at any depth you need rather than only at the tip. Shank outside diameter measures 0.3690 to 0.3750 in.
2) Is a Grade 5 hex tap bolt strong enough for mounting a motor to a machine base?
Yes, that's the intended use. The JG5HTB104 is a medium carbon steel cap screw, heat treated to Grade 5 with a minimum tensile and yield of 105,000 psi and hardness of Rockwell C19-30. It's also a common choice in automotive and truck repair. For higher-stress structural or high-torque joints, step up to a Grade 8 fastener instead.
3) What socket or wrench size fits these 3/8 inch Grade 5 hex tap bolts?
Head width across the flats runs 0.551 to 0.562 in., which is a 9/16 inch wrench or socket. Head height is 15/64 in., so a standard depth socket clears it fine. Plan for that size when you're mounting motors or doing repair work in tight brackets.
4) Can these zinc plated hex tap bolts be used outdoors or in a damp mechanical room?
The bolt is steel with a zinc finish, which handles indoor mechanical rooms, equipment rooms and general service conditions. Zinc plating gives sacrificial corrosion protection but it is not a marine or wash-down coating. For exposed exterior, coastal, or chemically wet locations, specify an 18-8 stainless hex tap bolt in the same 3/8-16 size.
5) How many bolts come in a jar of Metallics JG5HTB104, and can I buy fewer than 50?
It ships as a jar of 50 of the 3/8-16 x 3-3/4 Grade 5 hex tap bolts, and 50 is the order minimum. The jar pack keeps the count with you on the truck instead of loose in a tray. Other sizes and quantities are available by request.
6) Do these Metallics hex tap bolts meet Buy American and ARRA requirements for a public project?
The JG5HTB104 is flagged as both Buy American compliant and ARRA compliant in the manufacturer's data, with country of origin listed as China. On federally funded work, verify which rule your specification invokes, since the two programs treat fastener origin differently.
7) What steel is the Metallics Grade 5 hex tap bolt made from?
Stock conforms to AISI 1008-1026, a medium carbon steel range, and the bolt is heat treated to reach Grade 5 properties: 105,000 psi minimum tensile and Rockwell C19-30 hardness. That's the material note to hand a spec reviewer who wants the grade substantiated.
