This black RS PRO four-arm clamping knob can be inserted into an M6 threaded through-hole to keep your structural components firmly in place. It's commonly used with machinery, to fasten access doors or for domestic and industrial panelling.
The phenolic body material has strong resistance to abrasion and impact trauma, so it can withstand high levels of strain and can be fastened tightly. It also resists corrosion from rust buildups or chemicals, meaning you can be confident it will keep its shape in tough conditions. The metal alloy insert material provides improved strength and resistance to wear, so it will stay in good working condition for longer.
This product comes with a three-year warranty. It also conforms to Restriction of Hazardous Substances (RoHS) requirements, so you can be sure it contains only minimal amounts of any harmful materials.
