Minerallac 55020J – Frequently Asked Questions
1) Will the Minerallac 55020J bolt thread into standard 1/4-20 nuts and tapped holes?
Yes. It is a 1/4 inch diameter bolt with 20 threads per inch in coarse (UNC) pitch, so it mates with any standard 1/4-20 nut, coupling, strut channel nut, or tapped hole. It will not thread into a 1/4-28 fine thread hole.
2) Is a Grade 2 bolt strong enough for structural steel connections?
No. Grade 2 is a general purpose low to medium carbon steel fastener, and the Minerallac 55020J is Grade 2 steel. Use it for equipment assembly, panel and enclosure mounting, machinery mounting, and general MRO work. Structural steel bolted connections call for a structural grade fastener, not Grade 2.
3) What wrench or socket size do I need for a 1/4-20 hex head bolt?
A 1/4-20 hex cap bolt takes a 7/16 inch wrench or socket across the flats, which is the standard head size for that thread diameter. The Minerallac 55020J is a hex head bolt, so any standard open end, box, or six point socket in that size drives it.
4) Is this bolt fully threaded or does it have a shank?
It is partial threaded, so there is a smooth unthreaded shank below the head with the threads running up from the tip. The shank is useful when you want the bolt body to locate parts in a hole rather than having threads bearing on the hole edge. If you need thread the full length for a nut to run anywhere on the bolt, order a fully threaded tap bolt instead.
5) Can I use these zinc plated bolts outdoors or in a damp mechanical room?
The zinc plated finish gives corrosion resistance for indoor, dry, and lightly damp conditions, which covers most panel, strut, and equipment mounting work. Electroplated zinc is a thin coating, so for sustained outdoor exposure, washdown areas, or coastal air, go to hot dip galvanized or stainless 1/4-20 hardware instead.
6) Does the Minerallac 55020J come with nuts and washers?
No. The 55020J is the hex cap bolt only, 1/4-20 x 1-1/4 inch. Order matching 1/4-20 hex nuts and 1/4 inch flat or lock washers separately, or a 1/4-20 strut channel nut if you are fastening into strut.
7) Will these bolts match the finish of my existing zinc hardware on an electrical install?
They should. The head is a silver zinc plated finish, the same bright silver look as standard zinc plated strut hardware, channel nuts, and panel fasteners. Good for keeping a consistent appearance across an exposed conduit or equipment rack run.
