The Automann 210.1916 is a professional-grade, heavy-duty socket designed for the precise servicing of large-diameter axle and spindle nuts. Built for the rigors of the commercial trucking industry, this 6-point (hex) socket provides maximum surface contact to ensure safe and efficient wheel-end maintenance on Class 7 and 8 vehicles.
This 4-3/8" socket is engineered for high-torque applications where a secure, non-slip grip is vital. The 6-point design grips the flat sides of the fastener rather than the corners, significantly reducing the risk of rounding or damaging expensive axle components.
⚠️ 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 meet OEM bearing preload specifications.
