Metallics JG5HC21 – Frequently Asked Questions
1) Is a Grade 5 zinc plated bolt strong enough to mount a motor to a machine base?
Yes, that is the stated use for the JG5HC21. It is a medium carbon steel cap screw, heat treated to Rockwell C25-34, with 120,000 psi minimum tensile and 92,000 psi minimum yield. That is the usual spec for motor mounting and automotive or truck repair work. Zinc plating gives basic indoor and sheltered corrosion protection; for wet or coastal exposure a stainless or hot dip galvanized fastener is the better call.
2) Will a 1/4-20 bolt thread into a standard 1/4 inch tapped hole or nut?
It will. The thread is 1/4-20 UNC, 20 threads per inch, with a shank outside diameter of 0.2450 to 0.2500 inch, cut to ASME B18.2.1-2012. Any 1/4-20 nut, coupling, or tapped hole takes it. Note it will not fit a 1/4-28 fine thread hole.
3) Can I use these bolts on a Buy American or ARRA funded project?
No. The JG5HC21 Grade 5 hex bolt is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a federally funded job with domestic sourcing requirements you need a domestic Grade 5 hex cap screw instead.
4) How many bolts come in a jar of Metallics JG5HC21, and can I buy less?
These ship 100 pieces to a jar, and the jar is the minimum order unit, so 100 is the smallest quantity. Jar packaging keeps the count contained on a service truck or in a parts bin instead of loose in a bag. Other sizes and quantities can be had by request.
5) Are these hex bolts suitable for electrical and mechanical trade work rather than just structural use?
They are aimed squarely at the electrical, plumbing, and HVAC trades, which is why Metallics packages them in shop jars. Typical uses are bolting motors to equipment and general equipment and truck repair. For strut, channel, or hanger assemblies you would normally pair a 1/4-20 hex bolt like this with matching 1/4-20 nuts and washers, which are not included.
