Metallics JG5HTB68 – Frequently Asked Questions
1) Is this bolt threaded the full 3 inch length?
Yes. A hex tap bolt is threaded all the way to the head rather than having a plain shank, which is what separates it from a standard hex cap screw. The JG5HTB68 is 3 inches long with 11 threads per inch, right hand, so you get usable thread at any grip depth up to 3 inches.
2) Will a 5/8-11 Grade 5 bolt thread into a standard 5/8 inch tapped hole or nut?
It will. The thread is 5/8-11 UNC, right hand, made to ASME B18.2.1-2012, so it mates with any standard 5/8-11 nut or tapped hole. Body diameter runs 0.6170 to 0.6250 inch, so a 11/16 inch drilled clearance hole passes it in through-bolt applications.
3) Is Grade 5 strong enough to bolt a motor down to a base, or do I need Grade 8?
Grade 5 is the normal choice for mounting motors and machinery, and that is what this bolt is made for. It is medium carbon steel, heat treated to Rockwell C19-30, with 105,000 psi minimum tensile and yield. Step up to Grade 8 only where the engineered spec calls for the higher clamp load, such as high shock or high preload structural joints.
4) What size wrench or socket do I need for a 5/8-11 Grade 5 hex tap bolt?
The Metallics JG5HTB68 has a hex head measuring 0.922 to 0.938 inch across the flats, which is a 15/16 inch socket or wrench. Head height is 25/64 inch, with a wrenching height of 0.269 inch, so you need that much clear flat around the head for the socket to seat fully.
5) Can zinc plated Grade 5 hex tap bolts be used outdoors?
Zinc plated steel handles indoor and sheltered conditions and gives moderate corrosion resistance, which covers most motor mounts, equipment bases, and truck and automotive repair work. For sustained wet, washdown, coastal, or chemical exposure, specify 18-8 stainless or hot dip galvanized instead, since zinc plating is a thin sacrificial coating.
6) How many bolts come in a jar of Metallics JG5HTB68, and is there a minimum order?
The JG5HTB68 is packed as a jar of 25 bolts. The order minimum is 50 each, so two jars. The filled jar weighs 3280 g.
7) Do these bolts qualify for a Buy American or ARRA funded project?
Metallics lists the JG5HTB68 as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, so if your contract requires a single documented origin, request the certification for the specific lot being shipped.
8) Are nuts and washers included with these hex tap bolts?
No. The jar contains the hex tap bolts only. You order 5/8-11 hex nuts and 5/8 flat or hardened washers separately, and for a Grade 5 bolt at 105,000 psi you want the nut and washer rated to match the bolt rather than low carbon hardware.
9) I need 5/8-11 Grade 5 hex tap bolts in a different length. Can I get them?
Yes. Metallics offers the G5HTB and JG5HTB series in other sizes and quantities by request, so if 3 inches is the wrong grip length, a longer or shorter bolt in the same 5/8-11 zinc plated Grade 5 pattern can be sourced.
