Metallics JSHTB33 – Frequently Asked Questions
1) Is the Metallics JSHTB33 tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded, which is why the JSHTB33 is listed for complete thread engagement applications. The 1/2-13 thread runs the full 2 inch length, so it works where you need every bit of engagement into a tapped hole, channel nut, or strut insert rather than a shoulder of unthreaded shank.
2) Will a 1/2-13 stainless tap bolt corrode in an outdoor or damp mechanical room?
The JSHTB33 is 18-8 stainless steel, the standard austenitic grade used where plated carbon steel would rust out, so it holds up in damp mechanical rooms, exterior strut runs, and wash-down areas. Keep in mind 18-8 is a lower strength material than a Grade 5 plated bolt: 95,000 psi minimum tensile and 60,000 psi minimum yield. If your drawing calls for a specific SAE grade rather than a corrosion grade, stainless is not a drop-in substitute.
3) Can I use these stainless tap bolts on a Buy American or ARRA-funded job?
No. The JSHTB33 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For federally funded work carrying domestic sourcing requirements you will need a domestically produced fastener instead.
4) What wrench or socket size do I need for these 1/2 inch hex tap bolts?
Head width across flats measures 0.725 to 0.750 inch, which is a 3/4 inch wrench or socket. Head height is about 0.302 to 0.364 inch, so a standard shallow socket clears it fine in tight channel work.
5) How many bolts come in a jar of Metallics JSHTB33, and can I buy fewer?
They ship as a jar of 50 pieces, and 50 each is the order minimum, so the jar is the smallest unit. The jar pack keeps loose stainless hardware together on a service truck instead of spilling through a bin. Other sizes and quantities can be had by request.
6) Is the thread on the JSHTB33 standard right-hand coarse, and will my existing 1/2 inch nuts fit?
Right-hand thread, 13 threads per inch, which is standard 1/2 inch UNC coarse and manufactured to IFI-199 (2014). Any standard 1/2-13 nut, channel nut, or tapped hole will take it.
7) What trades actually use a 1/2-13 x 2 hex tap bolt like this?
It is stocked for electrical, plumbing, heating, and air conditioning work: hanging strut and trapeze, bolting pipe clamps and beam clamps, securing equipment feet, and anywhere a bolt threads directly into a tapped hole or channel nut. The 1/2-13 size is the common heavy-hanger thread in those trades.
8) How hard is the material on these stainless tap bolts, and will they gall when I run them down?
Hardness runs Rockwell B95 to C32. That is typical 18-8 territory, and stainless-on-stainless threads will gall if you drive them fast and dry, so run them in slowly or use an anti-seize on the thread. The 95,000 psi minimum tensile means they should not be torqued like a Grade 5 plated bolt.
