Metallics JG5HTB47 Bolts 1/2-13 X 1-3/4 G5 Hx Tap Blt S (Jar 50)

Yes. The JG5HTB47 is a 1/2-13 bolt, 13 threads per inch, right hand thread, cut to the ASME B18.2.1-2012 dimensional standard. Shank outside diameter runs 0.4930 to 0.5000 in., so it drops into a standard 1/2-13 tapped hole or a 1/2 inch clearance hole. Being a hex tap bolt it is threaded full length, which is what you want when you are pulling into a threaded hole rather than using a nut.

Grade 5 is the common medium carbon, heat treated class used for exactly that job, and Metallics calls out motor mounting plus automotive and truck repair as the typical uses. The spec is 105,000 psi minimum tensile with a hardness of Rockwell C19-30. If your drawing calls for Grade 8 or a metric class 10.9, this is not a substitute.

No. The JG5HTB47 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing requirements you will need a domestically produced Grade 5 fastener instead.

Across the flats the hex head measures 0.736 to 0.750 in., so a 3/4 inch wrench or socket is the fit. Standard for a 1/2 inch diameter hex bolt. Head type is a plain hex, no washer face flange or built-in washer, so plan on a separate washer if the mating surface needs one.

Finish is zinc plating over steel, which is a mild corrosion barrier suited to dry indoor and sheltered service. For sustained outdoor exposure, washdown areas, or anywhere near salt, step up to hot dip galvanized or 18-8 stainless in the same 1/2-13 x 1-3/4 size instead.

Fifty pieces, packed in a jar, and 50 each is the order minimum. The jar weighs 2722 g. If you need a different count or a different length in the same G5HTB family, Metallics offers other sizes and quantities by request.

A hex tap bolt like the JG5HTB47 is threaded the full length of the shank, so it can be run into a tapped hole at any grip depth and still engage threads. A partially threaded hex cap screw puts an unthreaded shoulder in the shear plane, which is preferred when the joint is loaded sideways and you are clamping through a clearance hole with a nut. For bolting a motor foot down into tapped holes in a base, the full thread tap bolt is the right pick.

Medium carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties, with a hardness of Rockwell C19-30 and 105,000 psi minimum yield. Plain carbon steel, so it is not magnetically inert and it is not corrosion resistant on its own, which is why it carries a zinc plate.
