RS PRO Clamping Knob, Black Polypropylene, Multiple Lobes, Threaded Through Hole, Brass Insert, 50 mm Diameter 188-3464

The RS PRO 188-3464 Multiple Lobes Clamping Knob provides an excellent solution for efficient manual clamping and control in industrial and engineering applications. This knob is expertly designed with multiple lobes, ensuring a robust and ergonomic grip for the operator, making it ideal for repeated use in machinery and hardware setups.

The knob body is precision-molded from high-quality black polypropylene, enabling superior durability and chemical resistance. Its threaded through hole mount, specified for M8 threads, allows for quick and secure fastening on a wide range of devices and equipment. The internal brass insert guarantees reliable strength and longevity, maintaining performance even in demanding environments.

For added user comfort, the knob incorporates a two-part molding structure, consisting of an inner polypropylene core and an overmolding of soft-touch TPE-39 styrenic thermoplastic elastomer. This combination provides excellent handling, reduces strain, and improves operational safety for frequent adjustments.

Technical attributes include a knob diameter of 50 mm, tensile strength of 11 MPa, tear strength of 30 kN/m, and an electrical resistivity of 8 x 10^15 ohm.cm. The density stands at 1160 kg/m³, while water absorption is controlled at only 0.05%, ensuring resilience against humidity or moisture. Abrasion volume is rated at 190 mm³, and molding shrinkage is 1.8%, fortifying the knob's long-term dimensional stability.

Elongation at break of 470% allows the material to withstand significant mechanical stress, supporting reliable manual clamp adjustments. The flame retardant property adds a layer of safety for industrial, laboratory, production, and workshop environments.

Common use cases for this clamping knob include industrial hardware, engineering materials, equipment handles, machinery controls, tool fixtures, and laboratory setups. Its robust construction and versatile installation make it a staple for maintenance, assembly, and control operations across commercial, manufacturing, and technical sectors.
