Fastening torque and breakaway torque

These two figures are not the same thing and the difference matters when you are comparing tools. Fastening torque is how tight it will do a nut up. Breakaway torque is how much it can apply to shift one that is already seized — always the higher number, because starting a stuck fastener takes more than tightening it ever did. At 1,898Nm breakaway this will move almost anything you meet short of a workshop press.

Hog ring or detent pin

The hog ring anvil lets you change sockets by pulling them straight off, with no tool and no pin to push. It is quicker, which is why it is preferred where sockets change constantly. The trade is that a worn ring eventually lets a socket work loose, so check it periodically.

Where it is used

• Truck, bus and plant wheel nuts
• Structural steel and bolted connections
• Heavy equipment maintenance
• Scaffold and formwork fixings

A warning worth heeding

An impact wrench of this capacity will snap a bolt or strip a thread without the slightest hesitation. For anything with a specified torque figure — wheel nuts especially — run it down on a lower mode and finish with a torque wrench. Use impact-rated sockets only; a chrome hand socket can shatter on a tool like this.
