Minerallac 40125J – Frequently Asked Questions

1) Are these coarse thread or fine thread nuts?
Coarse thread, right hand. That means they mate with standard UNC machine screws and bolts of the matching diameter, not UNF fine thread fasteners. If the screw in your assembly is fine pitch, these will not run on.
2) Will zinc plated steel hex nuts hold up outdoors or in a damp area?
Zinc plating on low carbon steel gives moderate corrosion resistance, which suits indoor panels, enclosures, and mechanical rooms. For sustained wet exposure, direct weather, or coastal and washdown areas, zinc plated steel is not the right choice; specify stainless or hot dip galvanized hardware for those locations.
3) Are these the right nuts for strut, anchors, or structural bolting?
No. These are machine screw nuts, Grade A low carbon steel, intended for machine screw assemblies, enclosure and panel mounting, and equipment maintenance. For structural or high tension bolting you want a graded heavy hex nut rated to the bolt grade, and for channel work you want strut nuts made for the channel profile.
4) What tool do I need to run these hex nuts?
Standard hex tools. The six sided body takes an open end or box wrench, a socket, or a nut driver of the matching across-flats size, so no proprietary bit is needed for electrical panel and enclosure work.
5) Do these Minerallac nuts come as a bulk pack for stocking a service truck or MRO crib?
They are sold in 100 piece packs, one thread size per pack, which is the quantity that makes sense for a parts bin or a truck drawer rather than a single repair. Order the 1/4 inch, 3/8 inch, and 1/2 inch packs separately to cover the common machine screw sizes.
6) Where are Minerallac hex nuts made?
China. That matters mainly to buyers with domestic sourcing requirements on public or federally funded work, so check your project spec before submitting these for approval.
7) What color are these nuts, and will they match existing zinc hardware in a panel?
Silver, from the zinc plating, so they blend with the typical zinc plated screws and washers already used inside electrical enclosures and equipment frames.
