The HTS Spares Steering Wheel Spinner Knob (Part No. HMP4157) is a precision-matched steering aid designed specifically to suit the HTL1874 steering wheel, secured via a standard M6 bolt for a firm, vibration-resistant fit. Also known in the trade as a spinner knob, Brodie knob, steering aid, or control knob for steering wheels - terminology varies by region and sector but all describe a rotating hand grip that fixes to the steering wheel to assist with smooth, efficient manoeuvring on plant and machinery. Whether you are maintaining a hire fleet or replacing worn components on an active construction site, having the correct OEM-matched part is essential for keeping machines productive and operators safe.
Steering wheel spinner knobs play a vital role in operator comfort and machine control across the plant hire and construction industries. They improve low-speed control, tight manoeuvring, and frequent direction changes - such as when loading, tipping, or shunting in yards - and help reduce arm fatigue during repetitive steering tasks on site. Under the Provision and Use of Work Equipment Regulations 1998 (PUWER), work equipment and plant must be maintained so that it remains safe, with an effective maintenance programme making plant and equipment more reliable. Replacing a worn or missing spinner knob is a straightforward way to keep mobile plant compliant, comfortable, and in proper working order. HTS Spares stock this part ready for despatch, minimising machine downtime for hire companies and contractors alike.
