Metallics JG5HTB15 – Frequently Asked Questions

1) How strong is a Grade 5 hex tap bolt, and is it strong enough for a motor mount?
Grade 5 medium carbon steel, heat treated, rated at 105,000 psi minimum tensile and hardness of Rockwell C19-30. Steel is per AISI 1008-1026. That is the normal strength class for mounting motors to machinery and for automotive and truck repair work. If your drawing calls for Grade 8, this is not a substitute.
2) Will the JG5HTB15 bolt pass through a 5/16 inch drilled hole?
The shank outside diameter runs 0.3065 to 0.3125 inch, so it is at nominal 5/16 and will not pass through an exact 5/16 inch hole without interference. Drill or punch a clearance hole, typically 11/32 inch for a 5/16 bolt, or use existing 5/16 clearance holes in channel and equipment feet.
3) What size wrench or socket fits a 5/16-18 Grade 5 hex tap bolt?
Across the flats the head measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the right tool. Head height is 13/64 inch, with 0.14 inch of wrenching height, so keep that in mind if you are working in a counterbore or tight pocket where socket access is limited.
4) Is the Metallics hex tap bolt zinc plated or stainless?
Steel with a zinc finish. Zinc plating handles dry indoor and sheltered conditions, mechanical rooms, equipment mounting, panel and motor work. For wet, coastal, or chemically aggressive locations, step up to a stainless hex tap bolt instead of relying on zinc.
5) How many bolts come in a jar of Metallics JG5HTB15?
They ship 100 to a jar, and 100 count is the order minimum. The jar runs about 2,463 g all in. Jar packaging suits a shop bench or a service truck bin where you are pulling a few at a time rather than opening a bulk box.
6) Does the JG5HTB15 hex tap bolt meet Buy American and ARRA requirements?
Metallics lists the JG5HTB15 as both ARRA compliant and Buy American compliant. Country of origin is China. On a federally funded job, check which standard your contract actually invokes, since Buy American compliance flags and domestic origin are not the same thing.
7) Do nuts and washers come with these hex tap bolts?
No. The jar contains hex tap bolts only. Order 5/16-18 hex nuts separately, plus flat and lock washers if your assembly needs them. Match the nut grade to the bolt so you are not pairing a Grade 5 bolt with an under-rated nut.
8) Can I get the Metallics G5HTB hex tap bolt in other lengths or diameters?
Yes, the G5HTB and JG5HTB series covers other sizes and pack quantities by request. The JG5HTB15 specifically is the 5/16-18 x 2-1/2 inch in a 100 count jar; the G5HTB prefix is the same Grade 5 zinc hex tap bolt in bulk rather than jar packaging.
