RS PRO Black Thermoplastic 4-Arm Clamping Knob, M8 Threaded Hole, 12mm Thread Length 702-7715

RS PRO 702-7715 is a black thermoplastic 4-arm clamping knob specifically engineered for industrial and mechanical applications requiring secure tightening and adjustment. The ergonomic 4-arm design enables enhanced torque generation and user comfort during manual operations. This knob has a 40 mm diameter and features a threaded hole mount compatible with M8 thread size and a 12 mm thread length, making it adaptable to various machinery and equipment fixtures.

The knob's body is crafted from impact-resistant thermoplastic, providing durability and resistance to environmental factors. It incorporates a steel insert for the threaded hole, offering excellent wear resistance and maintaining thread integrity over prolonged use. The matte black finish contributes to resistance against ultraviolet light exposure, chemical contact, and water absorption, promoting longevity.

This clamping knob operates efficiently within a temperature range of -20°C to +110°C, withstanding short-term peaks up to +170°C. It is suitable for applications such as industrial machines, food preparation units, medical furniture, access doors, clamps, and panels. The steel threaded inserts make it less suitable for outdoor or moist environments where corrosion resistance is critical; in such cases, stainless steel alternatives are recommended.

The RS PRO 702-7715 model ensures reliable mechanical fastening and ergonomic handling in workshop, manufacturing, HVAC, laboratory, and construction settings. Its robust design supports frequent and precise adjustments, enhancing operational safety and efficiency.
