❓ Frequently Asked Questions – Metric Wing Nuts M3–M12

🔹 Are these wing nuts compatible with standard US bolts?

These are metric thread (M series) wing nuts. They fit perfectly with metric bolts and screws (M3 to M12). For inch‑based (imperial) bolts, please check thread compatibility – most US DIYers use them on imported machines, 3D printers, or European furniture kits.

🔹 Can I use these zinc wing nuts outdoors or in wet conditions?

Zinc plating provides basic protection against rust, making it suitable for indoor and sheltered outdoor use (garages, sheds, covered patios). For continuous rain or saltwater environments, we recommend stainless steel options – but for most DIY and general industrial tasks, this zinc finish works great.

🔹 Do you sell individual sizes or only the full set?

You can select the exact size you need (from M3 to M12) using the product options above. No need to buy a full assortment – just pick the thread size that matches your bolts. Each order is priced per piece unless otherwise noted in the listing.

🔹 Will these wing nuts stay tight under vibration? (e.g., on lawn equipment)

Wing nuts are designed for hand tightening and frequent adjustments. For high‑vibration applications (engines, mowers), they may loosen over time. We recommend adding a lock washer or using a thread‑locking compound if a permanent hold is required. For static or low‑vibration tasks (furniture, racks, covers), they hold reliably.

🔹 What’s the warranty or return policy on these fasteners?

All GooBetter hardware comes with a 30‑day money‑back guarantee and 1‑year quality assurance. If you receive damaged or incorrectly threaded nuts, contact us for a fast replacement or refund – no hassle.
