Q: What is the difference between a wing bolt and a wing screw?
1. A: They function identically; the term generally reflects regional convention. We supply both under the same manufacturing standards.

Q: Are these suitable for food-contact environments?
3. A: Yes, the passivated stainless finish is hygienic and easy to clean, and we can supply a polished finish for food-processing equipment.
Q: Do you offer SS316 wing bolts for marine use?
4. A: Yes, the A4 (SS316) grade is our standard recommendation for boats, docks, and coastal installations.
Q: Can the wing be customized in size or shape?
5. A: Yes, we produce custom wing geometries to drawing for improved grip, torque, or brand appearance.
