New Spline Zero-degree Offset Combination Wrenches From Snap-on

The new Spline Zero-Degree Offset Combination Wrenches from Snap-on Industrial feature a uni-directional, zero-degree offset gear design to deliver more power in less lateral space, helping to access and remove the most stubborn fasteners in tight spaces. 

The Spline Zero-Degree Offset Combination Wrenches feature ratcheting gears with up to 60 teeth, and work in conjunction with an 8-tooth pawl, which together minimizes swing arc needed to remove fasteners in restricted spaces, such as found in aviation and other industrial applications. 

Additional features and benefits of the Spline Zero-Degree Offset Combination Wrenches include:

  • Cold-formed gears that use the same proprietary steel found in Snap-on sockets for added toughness and durability 
  • Flank Drive® wrenching system on box-end that generates up to 15-20% more turning power than conventional wrenches, while minimizing risk of tool or fastener damage
  • Manufactured from special alloy steel, precision forged and heat treated for optimal strength and durability
  • 16 sizes from 7/32” to 1”
