What do you do when you need a lot — and we mean a lot — of torque in a place where you don’t necessarily have power or air available? Kevin sent us a tip about a tool he used on nuclear-powered aircraft carriers while in the Navy that’ll fill that bill perfectly: the Swench Wrench.
It’s a spring-loaded impact wrench. As you turn the wrench, it stores energy by loading up a spring inside its head. Once you’ve turned the wrench about 30 degrees, it suddenly releases the spring, powering that energy back into the bolt or nut. Kevin said, “When three guys and a four-foot cheater bar couldn’t free a bolt, we brought out the swench.”
Kevin also said that their website is a bit cheesy but worth a look; He’s right. Their “little” model 625-50 cranks out 500 ft-lbs of torque, and their Goliath model 1500 spins up a whopping 7,000 ft-lbs. Now that’s some torque.
Pricing’s a bit whopping, too. The 13-5/8″ long 625-50 goes for $612, and the massive 39″ (to 60″ with extension handle) 1500 runs $4,400. Then again, it sounds like some of Swench’s prime buyer is the US government, who probably doesn’t flinch at this kind of pricing.
Yeah, it’s a bit expensive. But if we could afford one, we’d have one.
