Applications and selection
Assemblies designed for hand adjustment or access without a conventional wrench.
Specify the thread, wing span, height and material. Hand operation should not be treated as a defined tightening torque.

Common questions about wing nuts
Can I specify a precise tightening torque by choosing a wing nut?
The wing shape supports hand operation but does not establish a controlled torque. Follow the tightening method required by the assembly design.
Can I request a size or material outside this listing?
Yes. Send the required dimensions and exact material grade for review. A quotation is needed to confirm feasibility, price and lead time.
