Thermoset plastic clamping knobs offer durability, excellent strength, wear resistance, heat resistance, chemical resistance, and electrical insulation. Zinc plated metal threaded studs offer excellent corrosion resistance, durability, and protect the knobs from rust and wear. The knurled surface of the knob provides an enhanced grip surface for easy adjustment even with wet or oily hands. The thumb screw with a threaded stud attaches to a mating component for quick and easy installation. Tightly-in plated steel metal insert allows adjustment without additional tools. Clamping handles provide a secure grip and ultimate adjustment and tightening control, easy to use. Suitable for lathes, drill presses, saws, packaging and woodworking machinery, printing and instrument equipment, food and industrial equipment. Hold the knurled clamping knob with your hand and align the external threaded stud with the internal threads. Rotate the knob clockwise by hand to make sure it is securely fastened. Make sure to use the correct size bolt knob. If necessary, adjust the clamping force by rotating the knob clockwise (increases clamping force) or counterclockwise (decreases clamping force), allowing you to achieve the desired tightness or looseness for the specific application.
