✔️ 351 pcs black oxide star lock washers in M2-M12 set; with tweezer
This kit includes 351 star lock washers in nine metric sizes (M2, M2.5, M3, M4, M5, M6, M8, M10, M12) with an included precision tweezer, all stored in a clear plastic box for easy organization. The internal tooth design provides secure locking by increasing friction between the fastener head and the substrate, helping minimize loosening from vibration in electronics, mechanical assemblies, and DIY repairs. Constructed from durable 65Mn steel with a black oxide finish, these washers resist wear, corrosion, and rust for long-term use in challenging environments.

💡 What is a star lock washer and when should you use it in fastening?
Star lock washers bite into the surface and fastener head, creating friction that resists loosening under vibration. Handy for securing joints in electronics, mechanical assemblies, and automotive work.
- Used with metric fasteners M2-M12 for secure, repeatable fits - Improves preload and friction to prevent loosening during shocks or vibration - Ideal for DIY projects, hobby builds, and industrial setups
