  • These knurled thumb screws offer a versatile fastening solution for restoring lighting fixtures, lampshades, furniture, industrial machinery, home appliances, electronic devices, and various other applications requiring manual adjustment. Their textured grip design ensures aesthetic appeal and practical functionality across repairs, renovations, and professional maintenance tasks.
  • This pack includes 20 pieces of M3x6 knurled thumb screws, crafted from durable carbon steel material. Each screw has a 11mm / 0.43" head diameter and 3.7mm / 0.15" head thickness, offering a robust clamping force. The thread pitch is 0.5mm / 0.02". The knurled surface ensures a non-slip grip, while the surface zinc plating treatment finish adds corrosion resistance and a professional look.
  • These screws are made of quality metal with black zinc plated cover, which has higher corrosion resistance and anti-rust effect than ordinary screws, prolonged lifespan, are not easy to damage, and are more solid; Featuring a knurled texture on the head, these screws provide enhanced grip for easy hand-tightening, eliminating the need for tools. 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.
