Minerallac 40125-2500 Zinc-Plated Grade A Steel 1/4"-20 Hex Nuts, 2500-Pack

The Minerallac 40125-2500 is a bulk 2500-piece pack of 1/4"-20 hex nuts, engineered specifically for use with machine screws in electrical and industrial assembly work. Each nut is machined from Grade A steel and finished with a bright zinc plating for corrosion resistance and a clean silver appearance. With a coarse 20 thread pitch, right-hand thread direction, and standard hexagonal nut geometry, these fasteners provide dependable, code-compliant connections across a wide range of installation and maintenance applications where consistent thread engagement matters. Measuring 0.186 in in height and 0.437 in across the width, the compact standard-profile hex nut footprint makes it easy to drive with a standard wrench or socket while keeping panel and enclosure hardware low-profile. Electrical contractors, panel builders, and MRO teams rely on packs like this to keep production lines moving and maintenance stock replenished without running short mid-job. The 2500-piece bulk quantity makes the 40125-2500 an efficient choice for shops that consume large volumes of small hardware on a recurring basis, reducing reorder frequency and simplifying inventory management for maintenance and production teams alike.

Minerallac 40125-2500 – Frequently Asked Questions

1) Will these hex nuts thread onto 1/4-20 all-thread rod and strut hardware?
Yes. They are cut 1/4"-20 coarse, right hand thread, so they run onto any standard 1/4-20 UNC male thread, including all-thread rod, machine screws and strut fittings of that size. They will not fit 1/4-28 fine thread.
2) Are zinc plated steel hex nuts okay for outdoor or damp electrical work?
These are zinc plated steel, which is a coating for general indoor and dry protected work. Zinc gives light corrosion resistance but it is not the choice for direct weather exposure, wash-down areas, coastal air or corrosive process environments. For those, specify stainless or hot dip galvanized hardware instead.
3) How many nuts come in the Minerallac 40125-2500 and is it a bulk pack?
Model 40125-2500 is the bulk carton, 2,500 pieces of 1/4"-20 hex nut. It is a single packaged quantity, so it suits shops stocking a fastener bin or contractors running a long hanger and strut install rather than a one-off repair.
4) What grade are these 1/4-20 hex nuts and what does that mean for load?
They carry a Grade A rating in steel. Grade A is the general purpose carbon steel nut class used with standard low carbon machine screws and rod on ordinary hanging and mounting work. If a drawing calls out a higher strength assembly, such as a Grade 5 or Grade 8 bolted connection, match the nut to that bolt grade instead of using a general purpose nut.
5) What is the difference between a hex machine screw nut and a hex cap nut or coupling nut?
This is a plain hexagonal machine screw nut, made to pair with machine screws and threaded rod of matching size. A coupling nut is a long hex that joins two rod ends, and a cap or acorn nut closes off the end of the thread for appearance or to protect against snagging. If you need to extend rod, or cover an exposed thread end, a plain hex nut is the wrong part for that job.
6) Is the Minerallac 1/4-20 hex nut a standard silver finish that will match existing strut and hanger hardware?
The finish reads silver zinc plated, the same bright appearance as common zinc plated strut nuts, rod and channel hardware. On a retrofit where the existing hardware is zinc plated steel, these blend in. They will look noticeably different beside stainless or black oxide fasteners.
7) Where is the Minerallac 40125-2500 hex nut made?
Country of origin is China. That matters on public works and institutional jobs carrying domestic sourcing language, so check the spec section of your contract before committing this part to a Buy American or similar procurement requirement.
