RS PRO Black Two Part Mouldings Inner Moulding Polypropylene Over Moulded with Soft Touch Thermoplastic Elastomer 188-3460

RS PRO 188-3460 Clamping Knob is a high-quality mechanical hardware component designed for industrial and manufacturing applications requiring reliable manual clamping solutions. This clamping knob features a robust M6 threaded through-hole mount, allowing easy installation and secure attachment to various equipment and machinery.

The knob's diameter measures 28 mm, optimized for comfortable handling and manual adjustment in demanding industrial environments.

Constructed using advanced two-part moulding technology, the inner component is polypropylene, providing structural strength, while the exterior is overmoulded with a soft-touch thermoplastic elastomer, enhancing grip and operator comfort.

The use of a brass insert for the threaded female component ensures corrosion resistance and long-term durability under repeated use. Certified to meet UL94 HB flame retardant standards, this knob can be deployed safely in electrical and mechanical settings where fire retardancy is required.

Key mechanical and physical properties include tensile strength of 11 MPa, tear strength of 30 kN/m, and excellent electrical resistivity measured at 8 x 10^15 ohm.cm, making it suitable for both mechanical leverage and electrical insulation needs.

Additional material characteristics such as density (1160 kg/m³), minimal water absorption (0.05%), abrasion resistance (190 mm³), and controlled moulding shrinkage (1.8%) further demonstrate the product's reliability and dimensional stability.

The knob features a two-part moulding with an inner polypropylene base and a soft-touch thermoplastic elastomer overmoulding. Multiple lobe knob shape for superior grip and manual control. Brass female insert thread enhances durability and connectivity.

UL94 HB flame retardant certification ensures compliance with safety standards. Tensile strength rated at 11 MPa providing mechanical robustness. Electrical resistivity of 8 x 10^15 ohm.cm ensures effective insulation. Tear strength of 30 kN/m for high resistance to mechanical stress.

Density of 1160 kg/m³ and low water absorption of 0.05% increase durability. Excellent abrasion resistance of 190 mm³ maintains surface integrity. Moulding shrinkage controlled at 1.8% for manufacturing precision. Elongation at break of 470% allows flexibility under load.

This product is ideal for use in industrial tools and equipment, mechanical assemblies, and applications requiring reliable, ergonomic hand-operated Clamping Knobs.
