Product and application brief
A wing nut combines an internally threaded central body with two opposing wings that can be gripped by hand. It is a nut, not a wing screw: a wing screw has an externally threaded shank. Wing shape, central body geometry and thread system all help identify the required part.
Product forms and reference names
| Product form / field | Reference and distinguishing details |
|---|---|
| Rounded-wing reference | DIN 315:2016-12 is titled Wing nuts — Rounded wings. Its published overview covers M4 to M24, product grade C. This describes the reference scope, not a confirmed FastenerBridge supply range. |
| Edged-wing reference | DIN 314:1999-09 identifies Wing nuts — Edged wings. Keep this reference separate from rounded-wing products when describing the desired shape. |
| Inch-series reference | ASME B18.6.9 concerns wing nuts in the inch series. An inch thread designation and the selected specification are needed; this is not a DIN equivalence statement. |
| Drawing-defined wing nut | Use a drawing for special wing profiles, body heights, base details or other requirements not resolved by the selected reference. |
Shape and available space
Wing span and height matter where the nut is close to a panel, neighboring parts or a cover. The illustrated rounded-wing form is a generic appearance reference; it does not illustrate every DIN or ASME variant or establish exact dimensions.
Hand operation is not a load or torque rating
Wings provide a hand grip. Their presence alone does not establish a load capacity, tightening torque or suitability for a safety-critical connection. These requirements must come from the applicable engineering specification, not this product illustration.
Metric and inch descriptions
Provide the thread diameter and pitch or threads per inch, along with the requested reference and edition. Similar-looking wing nuts may use different thread and body dimensions. DIN and ASME references should not be treated as interchangeable or as a company conformity claim.
Specification fields
| Product form / field | Reference and distinguishing details |
|---|---|
| Thread | Metric diameter and pitch, or inch thread designation and TPI; state any specified thread hand or fit requirement. |
| Wing envelope | Overall wing span and height, grip shape and surrounding clearance constraints. |
| Body / base | Central body height and base geometry, including any drawing-defined details. |
| Material / finish | Material designation and requested finish; list separate mechanical or inspection requirements when needed. |
| Quantity / drawing | Quantity and unit, reference with edition or drawing number and revision. Mark dimensions still to be confirmed. |
Common product questions
Is a wing nut the same as a wing screw?
No. A wing nut has an internally threaded opening, while a wing screw has an externally threaded shank. The connection arrangement determines which part is needed.
Are DIN 314 and DIN 315 the same product reference?
No. Their published titles distinguish edged wings and rounded wings respectively. Select the intended reference and confirm its dimensional requirements.
Can an inch wing nut replace a metric wing nut?
Not on appearance alone. The mating thread and required geometry must match. A DIN or ASME reference does not establish interchangeability.
