RS PRO Clamping Knob Black Multiple Lobes Threaded Stud M10 x 30 mm Zinc Plated Steel Insert 188-3457

RS PRO 188-3457 clamping knob is a high-quality mechanical hardware component designed for use in industrial, laboratory, manufacturing, and mechanical assembly applications where secure and ergonomic fastening is required. It features a black multiple lobed knob with a 60 mm diameter that facilitates easy manual operation and precise adjustment.

The knob is manufactured using a two-part moulding process: an inner moulding of polypropylene combined with an overmoulded soft-touch thermoplastic elastomer (TPE-39 styrenic), delivering comfort and a secure grip during repetitive use. The threaded stud uses zinc-plated steel ensuring strength, durability, and corrosion resistance under harsh environments.

This product meets the HB (1.5 mm) UL94 flame retardant standard, making it suitable for electrical and electronic environments demanding safety compliance. It has mechanical properties including a tensile strength of 11 MPa, tear strength of 30 kN/m, and elongation at break of 470%, which attest to its robustness and durability under mechanical stress.

The electrical resistivity of 8 x 10^15 ohm.cm offers superior insulation properties making it suitable for applications requiring electrical isolation. Its density at 1160 kg/m³ along with a minimal water absorption rate of 0.05% and an abrasion rating of 190 mm³ ensure long-lasting resistance to environmental degradation.

The moulding shrinkage is controlled within 1.8% to maintain dimensional accuracy, important for precise fits in assemblies. The knob diameter measures 60 mm allowing good usability. Thread size M10 with a length of 30 mm accommodates standard fastening needs.

Material combination enhances ergonomic handling and grip. Zinc plated steel insert resists corrosion and mechanical wear. Flame retardant UL94 standard compliant for safety in electrical installations. High tensile and tear strengths provide mechanical reliability.

Low water absorption makes it suitable for humid or damp environments. Electrical resistivity assures safe use in electrically sensitive contexts. Overall, a durable and ergonomic clamping knob for demanding use cases.

This RS PRO clamping knob 188-3457 is ideal for use in engineering, mechanical fixings, and industrial equipment assembly where a reliable and ergonomic component is essential. Explore more RS PRO products in the Clamping Knobs category at EnvMart for comprehensive industrial hardware solutions.
