Product Description
The RS PRO 188-3452 Multiple Lobe Clamping Knob is a precisely engineered control element for secure fixing and adjustment in industrial assemblies. Featuring an M8 threaded stud and a knob diameter of 40 mm, this robust knob ensures firm mounting and easy manual tightening.
Constructed with a two-part moulding consisting of an inner polypropylene core and a soft-touch TPE-39 elastomer outer, this product balances durability with comfort. The ergonomic multiple lobe design allows for greater torque transmission while minimizing hand fatigue during repetitive use, making it ideal for machine setup and adjustment tasks.
The zinc plated steel insert delivers excellent tensile strength and corrosion resistance, supporting reliable performance across a wide range of mechanical and fluid power systems. With flame retardant properties and UL 94 HB approval, the knob is suitable for applications requiring high standards of material safety and compliance.
Key technical properties include tensile strength of 11 MPa, tear strength of 30 kN/m, electrical resistivity of 8 x 10^15 ohm.cm, abrasion rating of 190 mm³, density of 1160 kg/m³, and low water absorption at 0.05%. The knob is colour black and delivers dimensional stability thanks to low moulding shrinkage and high elongation at break.
Applications span engineering materials and industrial hardware sectors, commonly used on equipment needing manual adjustment and fixing such as clamping jigs, machine guards, fixtures, and laboratory set-ups. Suitable for manufacturing, assembly, electronics production, fluid power, and laboratory apparatus.
Multiple lobe design allows secure grip and enhanced torque. Threaded M8 stud ensures compatibility with standard fixing points. Polypropylene and TPE-39 structure provides mechanical durability and ergonomic comfort. Zinc plated steel insert for structural integrity and corrosion resistance.
Flame retardant, abrasion resistant, UL 94 HB rated for industrial safety. For the full range of industrial and mechanical hand tool accessories, explore Clamping Knobs and related hardware at EnvMart.
