Frequently Asked Questions
What is a wing nut used for?
A wing nut has two large perpendicular wings so it can be tightened and loosened by hand, without any tools. It is the standard choice for joints that must be opened or adjusted frequently, such as covers, clamps, rigs and quick-release fixtures.
When should I choose a stainless steel wing nut?
A2 (304) stainless steel wing nuts resist corrosion, so they are the better choice for outdoor, damp or marine environments, and for food or chemical contact where a plated finish is undesirable.
How strong is a wing nut compared with a hex nut?
Wing nuts are designed for convenience, not maximum clamping force — hand tightening cannot match a wrench. Use them for light-duty, frequently adjusted joints; use hex nuts for structural or high-load connections.
Do you provide material certificates?
Yes. Material test certificates per EN 10204 3.1 are available on request, and our manufacturing is ISO 9001:2015 certified. RoHS and REACH compliance documentation can also be provided.
