Wing nuts have two flat wings for finger grip. They are used where a part is often opened, adjusted or removed. The common standard is DIN 315.
Key dimensions of DIN 315 wing nuts with rounded wings in common sizes, in mm. The wing span is the width across both wings.
| Size | Thread pitch | Wing span (max) | Height (max) |
|---|---|---|---|
| M4 | 0.7 | 20 | 10.5 |
| M5 | 0.8 | 26 | 13.0 |
| M6 | 1.0 | 33 | 17.0 |
| M8 | 1.25 | 39 | 20.0 |

Typical dimensions as per DIN 315; refer to the standard for tolerances.
No. Wing nuts are made for hand tightening only. For a high clamping force, use a hex nut.
Choose the same thread as the bolt or stud, for example an M8 wing nut for an M8 bolt. Then check the wing span in the table above, so that there is room for your fingers to turn the nut.
Not on their own, because a hand-tightened nut has a low clamping force and can work loose. Add a spring washer under the wing nut, or use a nylock nut where the part does not need to be opened by hand.
