Questions about this product
- What thread sizes do these knobs come in?
- They cover metric threads from M4 up to M10. Knob diameters scale up too, roughly 25mm for the small ones and around 35mm for M10. Pick the size that matches your machine thread.
- What are these star knobs good for?
- They're made for tool-free clamping you adjust by hand. The star shape gives a non-slip grip for quick tightening and loosening. People use them on jigs, fixtures, 3D printer parts, and access panels.
- Why bakelite instead of metal or plastic?
- Bakelite (phenolic resin) is a good electrical insulator and handles heat well, around -40°C to +120°C. It also resists oils and solvents. The black oxide threaded inserts give a strong, corrosion-resistant grip on the threads.
