304 stainless steel threaded stud provides excellent corrosion resistance, oxidation resistance and high strength, ensuring durability and stability, preventing rust and providing reliable performance in various environments. The knurled texture on the hand knob surface provides better grip, making it easier to tighten or loosen the knob. The threads are neat and clear, the force is even and deep, not easy to slip, and there are no burrs. Tightly-in threaded metal stud insert is machine-injected at high temperatures to securely connect the parts together, easy to install. The matte surface enhances grip, making it easier and more comfortable to hold. Matte plastic is often more resistant to scratches and wear than glossy finishes, and is less likely to show fingerprints or smudges, maintaining a cleaner appearance over time. Knurled thumb screws are commonly used in applications that require frequent adjustments or tightening. The metric male hand knobs can be widely used in lathes, drill presses, sawing machines, packaging and woodworking machinery, printing, instrument and industrial equipment, and fixtures. Always tighten the threaded knob handle securely to prevent any movement of the fixed assembly. Do not over-tighten the knob as this may damage or strip the threads in the mating assembly. Replace the black plastic hand knob if necessary.
