I’m posting pictures of a Craftsman 15mm wrench vs a Snap On 15mm Flank Drive Plus wrench. Why 15mm? Well, in my collection of tools the 15mm is RARELY used. I don’t think I have ever used the Craftsman 15mm wrench. I wanted to be fair and if I used my craftsman 10mm to compare to a Snap On 10mm no one would ever buy a craftsman tool EVER again. The open end spread to almost 11mm, the head is HEAVILY twisted, and I broke the boxed end. All of this damage on a short Craftsman 10 mm without hanging any extensions on them.
The first thing you will notice is the 15mm Snap on is quite a bit longer. This is their standard length Flank Drive Plus unit. That extra leverage gives you more torque to bust bolts loose.
Moving on you will see that I used my Digital Caliper to measure the thickness of the wrench head on both sides of the open end. Take not that the Snap On wrench is exactly the same thickness all the way down to the .01 of an mm. The Craftsman unit isn’t even close. Just for the naysayer’s, I measured from multiple places on the open jaws of both units and the snap on was exactly the same for all of them, the craftsman varies WIDLY. The measurements represented are the closest I could get on the Craftsman. The tolerances vary even more then what is shown in the pictures.
Snap On:
Sorry for the blurry photo, but it says 6.89mm
&
6.89mm
Craftsman:
7.17mm
&
7.38
I tried to get a picture of this, but it just never turned out properly. Looking at the nose of the open end the jaws of the craftsman do not line up top and bottom. It is fairly dramatic; I just don't have the camera skills, or equipment to do the trick. The Snap On tool lines up perfectly.
I tried to get a picture showing the inside of the jaw but they were just too blurry and out of focus. Just to let you know the Snap On wrench has little grooves cut into it, and the Craftsman does not. These groves latch onto the fastener in a way that no other tool company has done yet. You will not round off the head of a bolt or a nut with these wrenches easily. YES if you are putting tons of torque on aluminum fittings and you’re not using a flare nut wrench it is possible to round off the edges, but this type of grasp is AMASING. I have personally rounded off a bolt with a non spread Craftsman wrench, grabbed a Snap On wrench and taken it off.
This is NOT my picture; I found it using a search engine and re-hosted it.
That is what Flank Drive Plus is all about.
You should be asking WHY it matters that the thickness of the tool being inconsistent, or not even close, or the fact that the tool doesn’t even line up should be a consideration on why someone should buy a tool. The main reason is those are SOME of the things NEEDED for a tool to grasp properly and function properly. On this alone I will never purchase another Craftsman tool that will get regular use. I know I will purchase a specialty low torque use tool or a tool that is retagged by Craftsman, but nothing more then that. It’s difficult for me to stay away from these tools because of the convenience of purchase and warranty, but to me the poor performance is not worth it. For some of you the extra performance isn't worth the additional money, and that is your choice. Craftsman works for millions of people every day. They are a good company making tools right here in the USA. And it is VERY difficult to turn my back on them for the majority of my purchases.
So, it comes down to what type of person you are, and what you expect your tools to do for you. If you’re a craftsman guy fine, that’s why we have more then one tool company out there. And the minute someone shows me a replacement or a new tool that works better then a snap on tool for less money, I'll be purchasing that. I for one am tired of working twice as hard to get a job done, tired of busted knuckles, broken tools that shouldn’t be broken, and warped/poor forgings. So far, none of my snap on tools has let me down, and I was a full time auto tech. I know that I will keep my tools for the rest of my life, so the additional cost to purchase the tool I KNOW will do the job correctly the first time, and have fewer failures, the small percentage in cost over another tool company is not that big of a deal.
