Logger Head Tools BW8-01R-01 Bionic Wrench 8-Inch 7/16-Inch to 3/4-Inch Adjustable Wrench

by Loggerhead Tools

Product Description

Amazon.com

The 8-inch Bionic Wrench is unlike any wrench you’ve ever seen before. In fact, it looks and works more like pliers than a wrench. This cleverly designed tool has a pair of spring-loaded handles and a circular head that’s fitted with six hardened steel jaws. As you squeeze the handles, all six jaws slide toward the center and lock onto the head of the nut or bolt. This unique mechanism allows the Bionic Wrench to grip hexagonal, square and even rounded fasteners. It fits six standard sizes ranging from 7/16 inch to 3/4 inch, and 10 metric sizes from 11 millimeter to 20 millimeters. This ruggedly built tool is made of hardened, cold-rolled steel and features a rust-resistant black-oxide finish. And it’s worth noting that the Bionic Wrench is proudly made in the USA and it’s guaranteed forever. -- Joseph Truini

From the Manufacturer

The Bionic Wrench is a remarkable patented hybrid of an adjustable wrench with the ease of use of a pair of pliers. In addition, the genius of attacking a bolt/nut on all 6 flat sides removes the stress and strain on the corners of the bolt. This, coupled with the superior gripping action of the jaws, allows the user to complete their work without the wrench slipping off and damaging the bolt. The design of the Bionic Wrench multiplies your hand's gripping force, so you can more easily tighten/loosen bolts. You can develop ratchet-like speed by fully turning the Bionic Wrench, release the grip while still on the bolt, reposition wrench, tighten grip-repeat until finished. The Bionic Wrench covers 16 sizes of fasteners from 7/16 to 3/4-inch and from 11 to 20 mm. Winner of 2005 Popular Mechanics Editor's Choice Award. Made in the USA.

3.0 out of 5 stars Not a replacement for standard open and/or box end wrenches..., April 18, 2006

Straight forward, they work. If you have easy access to the nut or bolt that you are trying to tighten/loosen they work really well and are comfortable to use.

But if you are working on anything that is a bit tricky to get access to (such as anything to do with exhaust systems or anything under the hood of a car) these fall way short.

You need a lot more horizontal (or vertical) movement with these then your standard wrenches. And there are just some things that you can't get a box end wrench on (this is how this tool works, very similar to a box end wrench).

All in all they work, but not as well as they would like you to think.

2.0 out of 5 stars Seems like it should work, but WHERE?, November 4, 2006

This review is from: Logger Head Tools BW8-01R-01 Bionic Wrench 8-Inch 7/16-Inch to 3/4-Inch Adjustable Wrench (Tools & Home Improvement)

I received this as a gift without ever having heard of the bionic wrench. After I figured it out -- which was not as intuitive as it probably should be -- I thought it would make a good replacement for an adjustable end (crescent) wrench, and possibly easier than finding the right socket. As it is, I have tried several times to use the bionic wrench, each time unsuccessfully. Sometimes I can't get it in to where I need it, and have to get my adjustable. Other times I can't get enough grip on the handle (because it interferes with the part surface) while the business end of the wrench is on a bolt, and I need a socket. Oh, and the grip it gets on a bolt head is too dependent on your hand strength, kind of like a channel-lock, so I wouldn't even try it at times when I know I'll need to put some muscle into getting a bolt broken loose -- too much chance of stripping the head.

It seems like it should be a great little tool, like a self-adjusting adjustable crescent wrench. Maybe I've just had difficult applications for it? I dunno, I've tried it several times and just don't have a real use for it.

Ingenious. I didn't use it on a tight nut/bolt where there may be a slippage problem for some one with a weak grip. It is great for all other situations and nullifies the need for lots of SAE & Metric wrenches. I suspect I'd prefer the old fashioned wrench for tight nuts/bolts or situations where my grip is insufficient to prevent slippage and subsequent damage to the nut/bolt (i.e. rounding).
