RS PRO Black Polypropylene Styrenic Thermoplastic Elastomer Multiple Lobes Clamping Knob M8 Threaded Through Hole 188-3466

RS PRO 188-3466 is a professional-grade multiple lobes clamping knob designed for mechanical, fluid power, and industrial hardware applications. This knob features a robust M8 threaded through-hole mount, making it compatible with a broad range of fastening needs where precise manual adjustment is required.

The knob diameter is 60 mm, providing excellent grip ergonomics. It is composed of a two-part moulding with a polypropylene core and a soft-touch TPE-39 styrenic thermoplastic elastomer over moulding, delivering both strength and comfort during operation.

The brass insert provides strong resistance to wear and ensures secure mounting on threaded studs. Its black color is achieved through durable materials that stand up to industrial environments.

Technically certified to UL 94 HB flame retardant standards, the knob offers flame resistance suitable for electrical and mechanical applications. Its tensile strength of 11 MPa and tear strength of 30 kN/m guarantee high mechanical integrity under load.

Additional material properties include an electrical resistivity of 8 x 10^15 ohm.cm, density of 1160 kg/m³, minimal water absorption at 0.05%, and abrasion resistance rated at 190 mm³. Moulding shrinkage is tightly controlled at 1.8%, and elongation at break reaches 470%, ensuring durability and flexibility for extended operational life.

This Clamping Knob serves diverse industrial uses, including mechanical assembly, laboratory equipment adjustments, and electrical hardware control knobs in manufacturing and maintenance settings.

The product is manufactured in China and supplied as new. It is a reliable hardware component for professionals seeking ergonomic and technical excellence in clamping mechanisms. The knob features a 60 mm diameter for comfortable grip and precise clamping.

It combines a polypropylene inner moulding and a soft-touch TPE-39 styrenic thermoplastic elastomer over moulding. The female insert is constructed from durable brass for secure attachment. Approved to UL 94 HB flame retardant standard ensuring safety in electrical and mechanical applications.

Exhibits high tensile strength of 11 MPa and tear strength of 30 kN/m for reliable mechanical performance. Electrical resistivity of 8 x 10^15 ohm.cm makes it suitable for electrical insulation purposes. Material density is 1160 kg/m³ with minimal water absorption of 0.05%, enhancing durability.

Low abrasion of 190 mm³ and controlled moulding shrinkage of 1.8% maintain dimensional stability. High elongation at break of 470% allows flexibility without fracture under load. Explore the RS PRO range for trusted components and industrial hardware in EnvMart's engineering and hand tools category.
