RS PRO Black Acetal Thermoplastic 2-Arm Clamping Knob, Push-in, 38 mm Diameter, 10 mm Thread Length 771-768

RS PRO 771-768 Black Acetal Thermoplastic 2-Arm Clamping Knob is engineered for industrial and mechanical applications requiring a secure and ergonomic manual fastening solution. This clamping knob, with a 2-arm design, is constructed from premium black acetal thermoplastic, providing superior mechanical strength, dimensional stability, and resistance to oils, solvents, and wear. The matt black Delrin acetal material delivers outstanding durability and a comfortable grip, ensuring precise torque control and ease of adjustment.

The push-in mount capability allows for tool-free installation and rapid assembly on panels, machinery, jigs, and fixtures. With a knob diameter of 38 mm and a thread length of 10 mm, it is optimally sized for integrating into a wide range of engineering hardware setups. A steel insert within the knob reinforces the internal structure, enhancing performance and extending service life.

This product is suited for thumb screw applications, enabling the assembly of threaded knobs by inserting a socket head cap screw into the knob cap (not supplied). Assembly is achieved by pressing components together squarely. To avoid over-pressure, a stop or spacer equivalent to the screw length minus the screw head depth is recommended, preventing damage during installation.

The ergonomic 2-arm design improves manual handling and facilitates quick adjustments, making it ideal for use in industrial machinery, equipment panels, laboratory setups, and production environments where reliable motion control and repeat fastening are critical. The black color delivers a professional aesthetic and improves visibility in operational settings.

Designed with compliance to engineering and mechanical hardware standards, this clamping knob finds application in manufacturing, maintenance, repair, and prototyping tasks. Its robust acetal thermoplastic body and steel insert ensure maximum reliability, even under frequent usage or exposure to harsh conditions.
