Product Overview

The YONK Double Box End Wrench is engineered for mechanics technicians and maintenance professionals who need a reliable high torque tool for fastener tightening and loosening in tight spaces.

Key Features


Premium CR-V Steel Construction

Each wrench is forged from high grade CR-V steel then heat treated for exceptional hardness toughness and wear resistance. The precision machined 12 point sockets provide full contact with fastener heads preventing rounding or stripping even under high torque. The black oxide finish offers excellent corrosion resistance protecting the wrench from rust and wear in harsh work environments.


Offset Double Box End Design    

The offset design provides clearance for knuckles while working in tight spaces allowing access to fasteners that cannot be reached with standard wrenches. The 12 point socket design allows engagement with both 6 point and 12 point fasteners offering versatility in various applications. The deep socket design provides a secure grip even on long or recessed fasteners.



Ergonomic Handle Shape

The contoured handle design provides a comfortable grip and maximum leverage reducing the effort needed to turn stubborn fasteners. The wrench is balanced for easy handling during extended use minimizing hand fatigue. The size markings are clearly stamped on the wrench body for quick identification helping users select the right tool fast.
