RS PRO Black Two Part Mouldings Inner Moulding Polypropylene Over Moulded with Soft Touch Thermoplastic Elastomer 188-3465

RS PRO 188-3465 is a high-quality clamping knob designed for industrial and mechanical applications. Featuring a diameter of 60 mm and an M10 threaded through hole mount, this knob provides reliable fastening with ergonomic multiple lobes for ease of use.

The knob is made using advanced two-part moulding technology, with an inner polypropylene core for strength and an over moulded 'soft touch' thermoplastic elastomer exterior ensuring comfortable grip. The female insert is made of brass for enhanced durability and secure mounting in threaded applications.

Featuring UL 94 flame retardant certification with an HB rating at 1.5 mm thickness, it complies with safety standards necessary for industrial environments. Key mechanical properties include a tensile strength of 11 MPa and tear strength rated at 30 kN/m, providing robustness for demanding conditions.

The knob exhibits superior electrical resistivity of 8 x 10^15 ohm.cm, offering excellent insulation during operation. Additional material characteristics include low water absorption of 0.05%, abrasion resistance quantified at 190 mm³, and moulding shrinkage of only 1.8%, all of which ensure long-lasting dimensional stability and reliability.

The design also includes a high elongation at break of 470%, allowing the knob to withstand mechanical stress and maintain integrity over repeated use.

This clamping knob is suitable for various industrial uses including mechanical fastening, fluid power controls, and tooling setups where comfort, safety, and durability are critical. It is widely applied across manufacturing, construction, and engineering sectors.

Manufactured in China, the RS PRO 188-3465 maintains rigorous quality standards expected from professional mechanical hardware components. Its black color and multiple lobe shape offer both aesthetic and functional benefits in industrial settings.

The knob construction combines polypropylene and thermoplastic elastomer for grip and strength. The brass insert adds reliability in threaded mounting applications. Certified compliance with UL 94 flame retardant standards supports safety requirements.

Offers high tensile and tear strength for extreme mechanical demands. Electrical resistivity ensures insulation in electrical or electronic environments. Low water absorption and abrasion values guarantee enhanced lifespan under humidity and wear.

Dimensional accuracy and mechanical flexibility are assured by low moulding shrinkage and high elongation at break. Explore more industrial hand tools and clamping hardware at EnvMart for reliable and professional-grade products tailored to your engineering and manufacturing needs.
