Ratchet-Handles Torture Test

Imagine you're at the junkyard and you've come across the Holy Grail of speed parts. It's the numbers-matching RamAirHemiYenkoShelby chingus you've long-since given up finding, and it's just waiting to be plucked from the rusty clutches of its engine bay. The problem is that you didn't bring your breaker bar, and the parts vultures are circling. Guys with reciprocating saws and impact wrenches have sniffed out your score and are just waiting for you to give up on your prize. Your only hope is your backup ½-inch drive ratchet handle and a length of pipe for punishing leverage. Will your ratchet be able to dish out the torque to break the bonds of rusty bolts?

We decided to find out, visiting several auto parts stores, a couple of hardware stores, and a swap meet to see what ratchets we could buy for about $20. These should represent what the average Joe has in the toolbox, especially a junkyard toolbox. We took them to Maxwell Industries and devised a scientific and repeatable test-to-failure program (see the Breakage sidebar). Here are the results of the tests. Endanger your knuckles at your own risk.

Breakage
The torture test was cooked up by Steve Watt of Maxwell Industries. Steve makes fixtures for testing shocks and has a device for measuring the spring rate of torsion bars. It was perfect for our demolition test. The ratchet's ½-inch-square socket mount was inserted into the fixture, and a hydraulic ram with a load sensor applied the force. The distance from the fulcrum to the ram was 1 foot when the wrench was parallel with the ground, so we didn't use any conversion to come up with our torque number; it was just the force in pounds at our 1-foot distance. The fixture wasn't altered during the course of our testing. The test reveals the maximum load under extreme flex—as when you slip a long pipe over the ratchet handle and stand on it to break loose an axle nut—and does not indicate performance under impact loads (hitting with a hammer).

What We Learned
The old, clunky ratchets we bought at the swap meet for peanuts are still kicking, although the old Craftsman seemed to “reset” itself at about half the torque of the Proto. The rest of the affordable ratchets were all imports, but all of the new teardrop-head ratchets look better than a new $25 tool should. They don't feel as high quality as the 72-tooth Snap-On ratchets we use in the Source Interlink Media Tech Center, but we also wouldn't dare bringing those into a junkyard. Also noteworthy was that the new Craftsman held its max torque level the longest before breaking, and the Duralast teardrop ratchet, which looks an awful lot like a truck-brand clone, posted almost 900 lb-ft. If you've got a bolt that won't budge after you've hit it with 600 lb-ft, let alone 800 lb-ft, step aside and let the vultures have it. It just wasn't meant to be.
