Metallics JG5HTB43 Bolts 5/16-18 X 1 G5 Hx Tap Blt St-zn (Jar 100)

Yes. A hex tap bolt is fully threaded, which is what distinguishes it from a standard hex cap screw with a plain shank under the head. The JG5HTB43 is a 5/16-18 x 1 inch bolt, right hand thread at 18 threads per inch, so the full 1 inch length engages a tapped hole or nut. That full engagement is why it is used for bolting motors to machinery and in automotive and truck repair.

The head measures 0.489 to 0.500 inches across the flats, so a 1/2 inch wrench or socket is the right size for the JG5HTB43. Head height is 13/64 inch, with a wrenching height of 0.14 inch, so there is limited bearing surface for the socket. Keep that in mind if you are working in a recess or using a deep well socket on a tight motor mount.

Zinc plating on steel is a mild corrosion barrier meant for indoor and protected use, machine rooms, panel work, equipment mounting. For direct weather exposure, wash down, or coastal air it will eventually rust through. Stainless 18-8 is the usual call for those conditions. The JG5HTB43 bolt body is steel with a zinc finish.

These ship as a jar of 100, and 100 count is the order minimum, so a jar is the smallest unit. Metallics does make the G5HTB and JG5HTB hex tap bolts in other sizes and pack quantities on request if you need a different diameter, length, or bulk box.

The JG5HTB43 carries both ARRA compliant and Buy American compliant flags in its product data, with country of origin China. If your contract runs under a stricter domestic-melt or domestic-manufacture clause rather than the ARRA designation, confirm the flag matches the clause your specification cites.

Threads are made to ASME B18.2.1-2012, 18 threads per inch, right hand, with the body outside diameter running 0.3065 to 0.3125 inch. That means they mate with any standard 5/16-18 UNC nut or tapped hole without a thread adapter. Steel is per AISI 1008 to 1026.
