Wing Nuts Details

What’s great about wing nuts, also called butterfly nutsあるいは wing bolts is that because of the two “wings” on either side of the nut, there’s no need to use a tool when tightening or loosening. There are variations in the design of wings, and they are typically made of steel, brass, zinc alloy, or nylon. A variety of sizes to fit most machine screws. If you don’t mind using a tool to tighten nuts on bolts, we’ve got a wide selection of hex nuts and lock nuts, too.A wing nut enables easy tightening and removal by hand. Use wingnuts to secure an access panel, marine hardware, or in other situations where handling a wrench is inconvenient. Use a zinc-plated stainless steel wing nut for exterior applications since their extra surface area makes them vulnerable to corrosion

Wing nuts are used for parts that are frequently disassembled & reassembled, wing nuts offer hand turning in applications where increased torque is not required. A steel wing nut’s large metal wings provide for easy hand tightening and loosening, without the need for tools.

Wing nuts are one piece nuts with two wings—180° apart—that protrude from an integral round base with a flat bearing surface. They are used in low-torque applications that require quick or frequent adjustment or disassembly and are intended to be tighten and released using your fingers.

It’s also called a butterfly nut (because of the “wings”) or a thumbnut (because it can be easily turned with the thumb and forefinger).

thumb nut provides similar functionality to the wing nut. It typically provides a ridged exterior flange that may be tightened by hand or with pliers. Thumb nuts do not apply to structural applications and tighten and loosen by hand.
