Metallics JG5HTB91 – Frequently Asked Questions

1) What size and thread is the Metallics JG5HTB91 hex tap bolt?
It's a 5/16-18 x 2-1/4 inch hex tap bolt: 18 threads per inch, right hand thread, with a shank outside diameter of 0.3065 to 0.3125 inch. Thread form follows ASME B18.2.1-2012, so it mates with any standard 5/16-18 UNC nut or tapped hole.
2) How strong is a Grade 5 hex tap bolt like the Metallics JG5HTB91?
Grade 5, medium carbon steel that's been heat treated. Minimum tensile strength is 105,000 psi and hardness runs Rockwell C19-30. That's the usual step up from an unmarked Grade 2 bolt for motor mounts, equipment bases and truck work where the joint sees real clamp load.
3) What wrench size do I need for these 5/16-18 Grade 5 hex tap bolts?
The hex head measures 0.489 to 0.500 inch across the flats, so a 1/2 inch wrench or socket is the fit. Head height is 13/64 inch, which matters if you're counting on clearance under a bracket or inside a motor base pocket.
4) Is a hex tap bolt fully threaded, or does it have a plain shank?
A tap bolt is threaded the full length of the shank, which is what separates it from a standard hex cap screw with a grip length. That's why it suits tapped holes of varying depth, like motor feet bolting into a machine frame, where you want thread engagement wherever the bolt happens to bottom out. If your joint needs an unthreaded shank riding in a reamed hole for shear alignment, a tap bolt is the wrong choice.
5) Will zinc plated Grade 5 bolts hold up outdoors?
The finish here is zinc plated steel, base material in the AISI 1008-1026 range. Zinc is a mild corrosion coating meant for dry or intermittently damp indoor and sheltered service, automotive and truck repair being a typical use. For sustained weather exposure, washdown areas or coastal work, go to 18-8 stainless or hot dip galvanized instead.
6) What is the part number for the 5/16-18 x 2-1/4 Grade 5 hex tap bolt in a 100 jar?
Metallics part number JG5HTB91. The leading J marks the jar pack; the same bolt in the G5HTB series is the bulk designation.
7) Where are Metallics JG5HTB91 hex tap bolts manufactured?
Country of origin is China. Worth knowing up front if you're buying against a domestic sourcing requirement on a public job.
