Metallics JG5HTB24 – Frequently Asked Questions
1) Is the Metallics JG5HTB24 hex tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded from the point to the head, which is what separates it from a standard hex cap screw with a plain shoulder. The JG5HTB24 runs 3/8-16 right hand thread over its full 2 inch length, so you can set your grip anywhere in that span and still get thread engagement in a tapped hole or nut.
2) Is a Grade 5 bolt strong enough for mounting a motor to machinery?
That is the intended use. Grade 5 is medium carbon steel, heat treated, rated at 105,000 psi minimum tensile and 105,000 psi minimum yield, with a hardness of Rockwell C19-30. For motor mounts, equipment bases, and automotive or truck repair work that is the standard structural fastener grade. If an engineered drawing calls out Grade 8 or a socket head cap screw, substitute up rather than using this.
3) What wrench or socket size fits a 3/8-16 Grade 5 hex tap bolt?
The head measures 0.551 to 0.562 inch across the flats, which is a 9/16 inch wrench or socket. Head height is 15/64 inch, so clearance over the head is minimal if you are working in a tight pocket.
4) Will zinc plated steel hex bolts hold up outdoors or in a wet mechanical room?
Zinc plated carbon steel is a mild corrosion barrier, fine for indoor mechanical rooms, equipment rooms, and dry structural work. In direct weather exposure, washdown areas, or anywhere near chlorides, the plating sacrifices and the base steel will eventually rust. For those openings move to a stainless 18-8 hex tap bolt in the same 3/8-16 x 2 size.
5) How many bolts come in a jar of Metallics JG5HTB24, and can I buy fewer?
The JG5HTB24 ships as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. The filled jar weighs 3044 g. Other sizes and quantities are available by request if 2 inch length or a 100 count does not suit the job.
6) Do these Metallics hex bolts meet Buy American and ARRA requirements for a federal job?
The JG5HTB24 is flagged compliant for both ARRA and Buy American in the manufacturer data, with country of origin listed as China. On federally funded work, verify which clause your contract actually invokes, since Buy American and Buy America have different domestic content thresholds.
7) What steel are these Grade 5 hex tap bolts made from?
Medium carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties. That is a weldable-adjacent carbon steel, but heat treating a Grade 5 bolt by welding on it destroys the temper, so do not tack these in place.
