NUT WING 1/4-20 SSAlways OEM - Nothing generic, "equivalent" or off-brand.
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.
A wingnut, wing nut or butterfly nut is a type of nut with two large metal "wings", one on each side, so it can be easily tightened and loosened by hand without using tools. A similar fastener with a male thread is called a wing screw.
