- This pack includes 20 pieces of M3x4 knurled thumb screws, crafted from durable carbon steel material.

The knurled surface ensures a non-slip grip, while the surface zinc plating treatment finish adds corrosion resistance and a professional look.

The flat head design ensures a flush, secure fit, making them good for applications requiring a sleek appearance.
- Simply grip the knurled head and rotate by hand to tighten or loosen. The textured surface provides a secure hold, even in tight spaces. Use them to fasten components in appliances, instruments, or DIY projects where quick, tool-free adjustments are needed.
- Please confirm the thread size. For optimal performance, avoid over-tightening, which could stress the threads.
