Metallics JG8HTB2 – Frequently Asked Questions
1) What size and grade is the Metallics JG8HTB2 hex tap bolt?
The JG8HTB2 is a 1/4-20 x 1 inch Grade 8 hex tap bolt in steel with a zinc finish. Tap bolt means it is threaded the full length of the 1 inch shank rather than having an unthreaded shoulder, so you get thread engagement right up to the head.
2) What nut do I need with a 1/4-20 x 1 Grade 8 tap bolt?
A 1/4-20 nut, and it should be a matched hardened grade if you want the joint to carry the bolt's strength. The JG8HTB2 ships as bolts only, so nuts and washers are separate line items.
3) Can I use a Grade 8 hex tap bolt instead of a Grade 5 for strut and equipment mounting?
Yes, Grade 8 is the higher-strength steel of the two and substitutes into anywhere a Grade 5 1/4-20 x 1 was specified. The reverse is not true: do not drop a Grade 5 into a Grade 8 callout. Grade 8 is also less forgiving of over-torque in soft or thin material because it will strip the threads in the softer part before it yields itself.
4) How much thread length do I get for clamping with the JG8HTB2?
The full 1 inch under the head is threaded, so your usable grip is 1 inch minus whatever the nut and washers take up. For stacking two pieces of strut or a thicker bracket, step up to a longer 1/4-20 length rather than running the nut out to the end of the threads.
5) Is a zinc plated Grade 8 bolt suitable for outdoor or damp locations?
Zinc plating on the JG8HTB2 is a general-purpose indoor and protected-location coating. It handles dry interior electrical and mechanical work fine, but for sustained wet exposure, exterior rooftop equipment, or coastal air you want a hot-dip galvanized or stainless fastener instead.
