Stainless Steel 316 Plain Color M12 Wing Head Nut for Metal Buliding
1. Product Description
A wingnut is a specialized, convenient item of hardware.
Like a normal nut, it has threads on the inside to engage the threads on a bolt or stud. However, instead of flat faces that must be engaged with a wrench (or Mr. Goodpliers), a wingnut has (typically) two large "wings" that allow it to easily be tightened or loosened with the fingers.
Wingnut is also a snarl word referring to anyone whom the speaker considers unreasonably far to the right, analogous to "moonbat."
