The Automann 210.1914 is a professional-grade, heavy-duty specialty socket designed for the precise removal and installation of 4-inch axle and spindle nuts. Engineered specifically for the commercial trucking and trailer industry, this 6-point (hex) socket provides the maximum surface contact required for high-torque wheel-end maintenance.
This 4" socket is a critical tool for any heavy-duty shop servicing Class 7 and 8 vehicles. The 6-point design is engineered to grip the flat sides of the fastener rather than the corners, which significantly reduces the risk of rounding off expensive spindle nuts under high load.
⚠️ Safety Note: This tool is precision-machined for MANUAL USE ONLY. Do not use with impact wrenches or power tools, as this can lead to tool failure or damage to the fastener. Use a manual breaker bar or torque wrench to ensure proper bearing preload according to OEM specifications.
