Metallics JG5HTB4 Bolts 1/4-20 X 2 G5 Hx Tap Blt St-zn (Jar 100)

It's a hex tap bolt, which means the 2 inch length is fully threaded 1/4-20 right hand thread, 20 threads per inch. That's the difference between a tap bolt and a hex cap screw with an unthreaded shoulder: full thread lets you run a nut anywhere on the shank or thread it straight into a tapped hole in a motor base or bracket. Thread form follows ASME B18.2.1-2012.

Outside diameter runs 0.2450 to 0.2500 inches. A drilled 1/4 inch hole is nominally the same size, so it will bind. Drill 9/32 or 5/16 for a clearance hole, or thread into a tapped 1/4-20 hole and let the full thread do the work.

Head width across flats measures 0.428 to 0.438 inches, so a 7/16 inch wrench or socket is the fit. The head is a standard hex pattern, nothing proprietary, and an open-end, box, or 7/16 socket all work.

Zinc plated carbon steel handles indoor and sheltered conditions fine, which covers most motor mounts, panel work, and equipment bases. Direct weather exposure, washdown areas, or coastal air will eventually take the plating and rust the steel, so for those go to an 18-8 stainless hex tap bolt in the same 1/4-20 x 2 size instead.

They ship as a jar of 100, and 100 count is the order minimum, so that jar is the smallest buy. The jar pack is what makes these practical on a service truck or in an MRO crib, you can grab a handful without a bag tearing open. Other sizes and quantities are available by request.

The JG5HTB4 is flagged compliant for both ARRA and Buy American in the manufacturer's product data, with country of origin listed as China. If your specification requires domestic melt and manufacture rather than the compliance flag, confirm that against the project's exact wording before you submit.

No. The jar contains the 1/4-20 x 2 hex tap bolts only, no nuts, flat washers, or lock washers. If you're bolting through rather than into a tapped hole, order 1/4-20 zinc hex nuts and washers separately.
