1. Multiple Sizes + Easy Operation, Adaptable to All Scenarios: Offers six common sizes – M3, M4, M5, M6, M8, and M10 – covering fastening needs in various scenarios such as small electronic devices, furniture assembly, and mechanical repair. The knurled cylindrical head design increases friction, allowing for easy tightening/removal by hand without additional tools, making it quick and easy to use for emergency repairs.
2. Nickel-Plated Iron + Stainless Steel Performance, Durable and Damage-Resistant: The base material is nickel-plated iron (or a process similar to stainless steel), combining high hardness (resistant to deformation and extrusion), rust resistance (the nickel layer isolates moisture from the air, resisting corrosion even in humid environments), and wear resistance and durability (the knurling and threads are reinforced, showing no significant wear even after long-term disassembly and assembly). Its lifespan far exceeds ordinary carbon steel screws.
3. A 20-Piece Set with Refined Craftsmanship, featuring 20 mixed specifications, meets diverse needs at once, avoiding repeated use due to incomplete specifications; the precision-threaded (high fit, non-slip teeth) and smooth, burr-free surface (will not scratch workpieces during installation), combined with high hardness and non-deformation stability, make it a versatile fastening helper for industrial repairs, home renovations, and DIY projects.
Whether for professional technicians' batch work or single repairs by home users, this multi-specification wing nut can easily become a staple in every toolbox due to its user-friendliness.
