Product description

  • Knurled Clamping Knobs Thread Size M6 (1mm Pitch); Thread Length 20mm 0.79"; Head Diameter 17mm 0.67"; Total Length 32mm 1.26"; Color Black. Safe and secure knurled thumb screws for the ultimate in adjusting and tightening control.
  • Features The knurled texture on the surface provides better grip, making it easier to tighten or loosen the knob. Threads are neat and clear, the force is even and deep, not easy to slip, and there are no burrs. Durable plastic knobs provide a smooth and beautiful surface as well as a comfortable grip.
  • 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.
