Product description


The Softline rim on the contact surface of the EN 4534 knurled knobs makes them particularly ergonomic and user-friendly.

The soft and slip-free surface works well with moist hands, oily surfaces, or high or low temperatures.

In addition to the soft surface, this knob has a large rim area that helps distribute the operator's contact grip and allows for higher torque to be achieved. It also makes these knobs a great choice for adjustment control applications.

The hard-plastic core provides guaranteed and perfect weight bearing anchoring of the tapped insert.
