RS PRO 686-092 Black Phenolic Clamping Knob with a multiple lobes design and M6 threaded stud is engineered for use in demanding industrial environments where secure fastening and ergonomic manual adjustment are essential. Its star-shaped multiple lobe configuration provides excellent grip and allows operators to effortlessly clamp, tighten, or adjust mounted equipment and fixtures without the need for tools.

The knob is manufactured using strong, wear-resistant phenolic material, complemented by a steel insert, to withstand repeated use and resist chemical and physical wear. This ensures reliability and longevity even with frequent handling in industrial and commercial settings. The 32 mm knob diameter offers a comfortable surface area for applying torque by hand while the M6 threaded stud and 15 mm thread length enable straightforward installation on compatible panels, access doors, clamps, and machinery.

A matte black finish gives the knob a professional appearance and enhances resistance to weak acids and solvents. This design is ideal for environments that require frequent adjustment or rapid set up, such as automation systems, access hatches, machine panels, fixtures, and drawer assemblies. The ergonomic, star-shaped structure not only improves efficiency in daily operations but also contributes to user comfort and safety.

With compliance to BS771 and EN61340 standards, this clamping knob is well-suited for electrically sensitive and safety-focused applications. Its functional temperature range of minus 30°C to plus 85°C ensures consistent performance both in chilled environments and in areas exposed to moderate heat. The phenolic material’s high melting point of approximately 215°C and resistance to chlorinated hydrocarbons further enhance its industrial versatility.

This knob finds widespread use throughout manufacturing plants, maintenance shops, machinery assemblies, commercial furniture, laboratory equipment, HVAC systems, and custom enclosures requiring robust hand-operated fastening mechanisms. Whether for industrial panels or commercial fixtures, the RS PRO 686-092 knob delivers quality and performance trusted by professionals.
