Minerallac 55433J – Frequently Asked Questions
1) What nut and tapped hole size do I need for the Minerallac 3/8-16 hex cap screw?
It takes a 3/8-16 coarse thread nut or a tapped hole in 3/8-16 UNC. The size is 3/8-16 x 2 inches with a coarse thread type, so any standard 3/8-16 hex nut, flange nut, or 3/8-16 tapped strut channel nut will mate with it. Fine thread 3/8-24 hardware will not.
2) How do I confirm on site that the bolts I was shipped are actually Grade 5?
Look at the top of the hex head. Grade 5 carries three radial hash marks, and these screws are marked that way. No marks means Grade 2, six marks means Grade 8. Inspectors on commercial jobs check this, so it is worth a glance before you install a run.
3) Can zinc plated hex cap screws be used outdoors or in a wet mechanical room?
Zinc plated is a corrosion resistant coating suited to damp interior areas and sheltered exterior use. It is not the same as hot dip galvanizing or stainless, so for direct weather exposure, coastal air, or anything submerged or chemically washed down, go with a hot dip galvanized or 304/316 stainless fastener instead. The head finish is silver.
4) Will this hex cap screw work for hanging strut, conduit racks, and other electrical supports?
Yes, that is a common use. It is a 3/8-16 x 2 inch hex cap bolt from Minerallac's hangers, supports and fasteners line, and 3/8-16 is the standard thread for strut channel nuts, beam clamps, conduit hanger rods, and trapeze supports. Pair it with a 3/8-16 channel nut or spring nut for strut, and add a flat washer where the hole is oversized.
5) Do these hex cap screws come with nuts or washers?
No. The Minerallac 55433J is the hex cap screw only, 3/8-16 x 2 inch, zinc plated. Order 3/8-16 hex nuts and 3/8 inch flat or lock washers separately if the connection needs them.
6) What wrench or socket do I need for a 3/8-16 hex cap screw?
A 9/16 inch wrench or socket fits the hex head on a standard 3/8 inch cap screw. Head height is 15/64 inch, so a thin wall socket clears easily in tight channel or bracket work. No driver bit is involved, it is a plain hex head.
7) Does a partial thread hex cap screw matter, or can I use a fully threaded bolt instead?
It matters in shear joints. The partial thread leaves an unthreaded shank under the head, which puts solid body rather than thread roots in the bearing plane and helps the parts seat and share load. For through bolted brackets and equipment feet that is what you want. Fully threaded bolts are fine when you are threading deep into a tapped hole or need adjustment over the full length.
