The Automann 210.1917 is a heavy-duty specialty socket designed for the precise removal and installation of large-diameter axle and spindle nuts. Built for the commercial trucking and trailer industry, this 8-point (double-square) socket provides the stable grip necessary to handle the high-torque requirements of wheel-end maintenance.

Product Overview

This tool is engineered to fit 4-3/8" fasteners perfectly, reducing the risk of slippage that can lead to damaged hardware or injury. The 8-point geometry is specifically designed to accommodate the octagonal or square-head nuts frequently used in heavy-duty hub assemblies.

⚠️ Safety Note: This is a precision-machined tool intended for MANUAL USE ONLY. Using an impact wrench with this socket can cause tool failure or damage the fastener. Always use a manual breaker bar or torque wrench to ensure proper bearing preload.
