Metallics JSHB36G – Frequently Asked Questions
1) What thread size and length is the Metallics JSHB36G square head bolt?
It's a 1/2-13 x 3-1/2 inch square head bolt. The 1/2-13 means a 1/2 inch nominal diameter with 13 threads per inch, which is the standard UNC coarse thread for that diameter, so it mates with any standard 1/2-13 hex or square nut. Overall shank length is 3-1/2 inches under the head.
2) How many bolts come in a jar of Metallics JSHB36G?
Twenty-five bolts per jar. Metallics packs the JSHB36G in a jar rather than a loose box, which is why it works well on a service truck or in a shop bin where you want the 1/2-13 x 3-1/2 size kept separate and countable.
3) What is the difference between a square head bolt and a hex head bolt for electrical work?
The head shape is the difference, and it changes how you drive it. A square head like the JSHB36G gives you four flats instead of six, so an open-end wrench or adjustable gets a deeper bite in tight quarters and the head is less likely to round off under heavy torque. Hex heads turn in smaller increments and suit socket work better. Square heads are the traditional choice on strut, channel, and structural electrical mounting where the head sits against a bracket and gets wrenched rather than socketed.
4) What is the exact part number to order the Metallics 1/2-13 x 3-1/2 square head bolt?
Order Metallics JSHB36G. That number covers the 1/2-13 x 3-1/2 inch square head bolt supplied in a 25-count jar, so a distributor or purchasing desk can specify it as a single line item rather than calling out size and pack separately.
