• Hand Knob with Stud: Zinc plated carbon steel threaded studs on knurled knobs ensure durability, strength, functionality and wear resistance. The tightly-in metal threaded stud can securely join components together, easy to install, suitable for various applications.
• Features: The knurled texture on the 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.
• Applications: Knurled knobs are commonly used in applications that require frequent adjustments or tightening. Widely used in lathes, drill presses, sawing machines, packaging and woodworking machinery, printing, instrument and industrial equipment, and fixtures.
• Tips: Always tighten the knurled knob 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 knob if necessary.
