Descriptions:
Star design adjusts and tightens easily for maximum control and flexibility without the need for additional tools. Clamping handle knobs feature tightly-in metal insert (won't strip) for a variety of threaded applications, making it easy to install and secure in place.
Star knobs are made from plastic material ensuring durability and long-lasting performance. Brass metal screw-in female threaded insert offers high strength and corrosion resistance for long service life. The threads are neat and clear, the force is even and deep, not easy to slip, and there are no burrs.
Through hole female star handles allow for easy installation and removal, versatile mounting options. Sturdy and durable threaded knobs provides a smooth surface, comfortable grip and ergonomic operation for enhanced user control and ease of use.
Star knob handles are widely used in machinery, electronics, equipment, furniture and can be used on drill presses, lathes, routing jigs, fixtures, packaging and woodworking machinery, printing equipment.
If you need the flexibility of easy installation and removal, choose a through-hole design. If direct mounting is preferred or space constraints exist, choose the non-through-hole design.
Tips: Ensure that the knob is securely and properly installed on the corresponding male threaded component or fastener. Choose the star knob size that suits your needs. Do not over-tighten as this may cause damage of the knob or threaded parts.
