Metallics JG5HTB51 – Frequently Asked Questions
1) Is the Metallics JG5HTB51 hex tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded, which is what separates it from a partially threaded hex cap screw of the same 1/4-20 size. On the JG5HTB51 that means right hand threads at 20 threads per inch running the full 2-1/4 inch length, so you get full engagement in a tapped hole or a nut regardless of how deep you go.
2) Will a 1/4-20 Grade 5 hex tap bolt pass through a 1/4 inch drilled hole?
The bolt's outside diameter is 0.2450 to 0.2500 inch, so it is right at nominal 1/4 inch and will bind in a hole drilled exactly 1/4 inch. Drill 9/32 inch for a clearance hole, or tap 1/4-20 if the bolt is threading directly into the part.
3) How strong is a Grade 5 hex tap bolt, and is it strong enough for mounting a motor?
Grade 5 medium carbon steel, heat treated, rated at 105,000 psi minimum tensile and 105,000 psi minimum yield, with a hardness of Rockwell C19-30. That is the normal choice for bolting a motor to a base or machine frame and for automotive and truck repair work. If your drawing calls out Grade 8, this is not a substitute.
4) Are these zinc plated bolts suitable for outdoor or wet locations?
The finish is zinc on steel, which handles indoor and sheltered mechanical rooms, equipment skids and vehicle work. Zinc plating gives limited corrosion protection, so for direct weather exposure, washdown areas or coastal sites step up to 18-8 stainless in the same 1/4-20 hex tap bolt pattern.
5) How many bolts come in a jar of Metallics JG5HTB51?
Each jar holds 100 pieces, and 100 count is also the order minimum, so the jar is the base purchase unit. Jar packaging keeps loose fasteners contained on a service truck or on a parts shelf rather than spilling in a box. Other sizes and quantities can be requested.
6) Do Metallics Grade 5 hex tap bolts meet ASME dimensional requirements for a government job?
The threads conform to ASME B18.2.1-2012 and the steel is AISI 1008-1026. Metallics also flags the JG5HTB51 as ARRA compliant and Buy American compliant, with country of origin China. On federally funded work, verify which of those compliance paths your contract actually requires, since the two are not the same test.
7) Do nuts and washers come with these 1/4-20 hex tap bolts?
No. The jar contains bolts only, so order 1/4-20 nuts and 1/4 inch washers separately if the bolt is not going into a tapped hole. Any standard 1/4-20 right hand nut will thread on.
