Yes. They are manufactured to metric thread standards and fit M3, M4, M5, M6, M8, M10, and M12 sizes – the most common range found in DIY, furniture, and light machinery.
A2 stainless steel (304 grade) offers excellent corrosion resistance for typical indoor and outdoor environments. They resist surface rust far better than carbon steel, but for saltwater or marine settings, we recommend a higher-grade stainless option.
No tools required. The wing design is made for hand‑tightening, which gives you fast, convenient adjustments and a secure hold in seconds.
Each wing has one hole per leaf, making it easy to thread safety wire, attach a retaining lanyard, or hang very light items. It’s a small detail that adds extra security for vibration‑prone applications.
This is a multi‑size assortment covering M3 through M12. The exact piece count may vary – please refer to the listing photos and quantity selection for your specific kit breakdown.
