Metallics JSHTB471 – Frequently Asked Questions
1) Is the Metallics JSHTB471 hex tap bolt a fine thread or coarse thread 1/2 inch bolt?
Fine thread. The JSHTB471 is a 1/2-20 bolt, 20 threads per inch, so it mates with 1/2-20 fine thread nuts and tapped holes only. A standard 1/2-13 coarse nut will not run onto it. Worth confirming before you pull from the jar, since coarse is the more common 1/2 inch pitch on general steel work.
2) Will stainless tap bolts hold up outdoors or in a damp electrical vault?
The JSHTB471 is 18-8 stainless steel, the austenitic grade used for general outdoor, damp, and washdown service where a zinc plated bolt would rust out. It is not a hardened alloy fastener, so pick it for corrosion resistance rather than maximum strength: it carries a 95,000 psi minimum tensile and 60,000 psi minimum yield.
3) Do these stainless tap bolts qualify for a Buy American or ARRA funded project?
Metallics lists the JSHTB471 as both Buy American compliant and ARRA compliant, which is what a government, school district, or utility procurement officer needs on the submittal. Country of origin is listed as multiple.
4) What is a hex tap bolt and how is it different from a regular hex cap screw?
A tap bolt is threaded the full length of the shank rather than having a plain grip section under the head. That matters when you are running the bolt into a tapped hole or a blind hole of uncertain depth, or clamping a thick stack where a partially threaded bolt would bottom its unthreaded shoulder in the nut. The Metallics JSHTB471 is a hex head tap bolt in 1/2-20 x 1-1/2.
5) How many bolts come in a jar of Metallics JSHTB471?
Fifty pieces, packed in a jar, and 50 each is the order minimum. Metallics lists other sizes and quantities by request if you need a different count or length for a job.
6) Can I use these stainless bolts with galvanized strut and steel channel?
You can, but think about the pairing. Mixing 18-8 stainless with zinc or galvanized hardware in a wet location sets up galvanic action that eats the zinc coating first. For dry interior strut runs it is a non-issue; for exterior or wet vault work, run stainless bolts with stainless nuts and washers. Note also these are 1/2-20 fine thread, so your nuts have to match the pitch.
7) Are nuts and washers included with the JSHTB471 jar?
No. The jar holds 50 hex tap bolts only, 1/2-20 x 1-1/2 in 18-8 stainless. Order matching 1/2-20 fine thread nuts and stainless flat or lock washers separately to complete the assembly.
8) What thread standard do these Metallics hex tap bolts conform to?
Threads are produced to IFI-199 (2014), so they interchange with any nut or tapped hole cut to the standard 1/2-20 UNF form. Hardness runs Rockwell B95 to C32.
