What it is

MIDWEST FASTENER CORP 03805 Wing Nut 5/16"-18 Steel Zinc 100 PK is a box of one hundred zinc-plated steel wing nuts. Each nut features a pair of extended wings for tool-free tightening and loosening by hand. The hardware is designed for assemblies that require frequent tension adjustment or quick removal. It suits maintenance kits, fixture building and field repairs where speed matters.

Thread spec that matters

The nuts use a 5/16"-18 thread size, so they only mate with bolts or studs cut to that exact diameter and pitch. Verify the mating hardware before ordering because a different thread will not engage. The unified coarse pitch is standard for many structural and automotive fasteners. No other thread option is offered in this pack.

How it fits a build

The zinc coating provides basic corrosion resistance for indoor or sheltered outdoor use. Wings clear the fingers for rapid hand operation, freeing the builder from carrying a wrench or socket. The hundred-count quantity supports repeated disassembly cycles on jigs, clamps or temporary structures. Buyers who need a different thread pitch, a locknut feature or stainless steel should look elsewhere.

Questions about this item

What does the 5/16"-18 thread size mean when I am matching this wing nut to a bolt or stud?

The 5/16" is the nominal diameter and the 18 means there are 18 threads per inch, so it will only fit a matching 5/16"-18 bolt or threaded rod.

How does the wing design change the way I tighten or loosen this nut compared with a standard hex nut?

The two extended wings let you spin the nut on or off by hand without any wrench or socket, which is useful when adjustments or removals are frequent.

What clearance do I need around the nut so the wings can turn freely in my assembly?

The wings project beyond the thread diameter, so allow enough space for the wing span to rotate without hitting brackets, panels or adjacent hardware.
