craftsman professional ofset wrenches $15

[rsanter]

just got back from the local sears to get a couple of broken wrenches replaced. took a look at the clearance section and they had the 5 piece full polished offset wrench sets SAE for $14.97
sears number 9-44349 has 3/8 to 15/16

this set is usually $40-$45 so I could just not pass these up.
I am not sure how much I will use these, I have some of the older raised pannel version that I have used a bit but like I said I just could not pass up the shiney stuff.

I know some of you have wanted then so take advantage while you can

Not in my clearance section, I was just there. Would you pick up a set for me though?

EDIT: Nevermind. I see you posted the #. I'll just pick up the set tomorrow and scan it. Maybe it is on clearance and they just didn't put it in the section.

 

[dxdexter]

That's a great deal, but I am curious: how did you manage to break the wrenches? I have broke a few sockets and a flex handle, but never managed to break a wrench.

 

[rsanter]

I generally break the 12 pt box end as I prefer the use of the box end for breaking things loose.
if you have a bolt that has been there long enough and it has some rust on it (we call it rust holding hands) that will just not let go......
I have broken most of the common sizes used from 1/4 all the way up to 1''.
yes I actually broke a 1'' wrench...the guy at sears looked at the wrench and asked how I broke it. I told him I pulled real hard. if he had asked any more about it I was going to offer to arm wrestle him over it

I have broken lots of 1/2 and 9/16 over the years

I have broken 12 pt box ends, too.

Arm wrestling...I never thought of that...

I hit them with a hammer and don't break them. The rusted bolt should be breaking before the wrench is.

The wrench should be stronger than the fastener. However there is another factor involved - fatigue. The fastener has probably been stressed only a couple of times. Once when tightened and a second time when loosened. A wrench is stressed each time that is used. Most of us stress our wrenches many thousands of times. This can lead to fatigue failure.

A simple experiment can demonstrate the effects of fatigue. Take a piece of wire and bend it at a sharp angle. It does not break. Bend it back and forth several times, and eventually it will break. This is a fatigue failure.

That said, I have broken far more fasteners than wrenches.

 

[eschoendorff]

Never broken a wrench. If a fastener is that stubborn, I usually break out the heat, PB and an impact socket WAAAAAY before I would even come close to breaking a wrench.

God I wish I had seen this earlier. I hope they're on clearance here, time to ditch my crappy sk wrenches and say bye-bye to the last sk tools in my box.

depending on how you alloy it, metal can be strong (hard) or strong (tough) or a combination of the two. it seems to be cheaper and easier to make them hard than tough.
Cman wrenches are hard and will snap under excess load.

if a 1" wrench is about 1 ft long and I put all my weight on it then I can exert about 230 ft-lbs on it. if my friend Tommy is leaning it on as well then we can put about 500 ft-lbs on it.
now if we both put a foot on the tractor to push against while we are pulling on the wrench then we can exert likley 700-800 ft-lbs on that wrench.
from experience if you do that the wrench will break, you and your friend will hit the ground and you will sprain you ankle in the process.
you will then limp into the local sears (and will be a little ticked off) and ask then to warranty said 1" wrench and the bolt will still be in place to get you another day.

I have broken two Craftsmans and an old Bonney.

I seem to recall I was jumping on the Bonney...

I think what you are referring to is the elastic modulus and shear modulus of different alloys. Ideally the object would deform elastically, meaning it will return to its original shape. However, when the force is great enough it becomes inelastic so it will not return to original shape. After that it breaks. Some metals jump right to the failure and practically skip the elastic/inelastic stages. Very bad since they give you no warning. I know this is common logic/sense, but I felt like sharing since my professors have been preaching it all week(in far greater detail of course)...

Why do you think these were on clearance? Usually the tool sets I see in the clearance section are missing some of the tools.

That makes me wonder if they are going to bring in a new line of offsets by a different manufacturer, or they are going to discontinue something.

Sort of, but not quite. You're talking about the non-linear portion (failure portion) of the stress/strain curve for a given material. The linear portion of the slope is the elastic (Young's) modulus of the material. The shear modulus is similar, in that it describes deformity (strain) vs force/area (stress) but it is talking about the shear plane. Think of a cube of jello, now imagine pulling the top one way and the bottom the other, the sides would slant. The amount that the top moves in relation to the bottom for a given stress is the shear modulus. For each of those moduli, there is a linear portion for most materials, but when you get outside the linear region the behavior is different (necking, then failure).

What happens in a repeated loading situation is that the crystalline abnormalities in a substance all line up eventually creating a fault that is big enough to cause failure (remember that a substance derives its strength from its very regular crystalline structure).

Yeah, you're right. I was referring to the strain at failure. I don't know why I said shear. Please, do not talk about deformed cubes(even if I need to hear it). I am tired of looking at deformed cubes!

I haven't learned about that yet. We just recently covered the moduli.

Enjoy basic engineering while it lasts... I only wish I could deal with stress/strain and repeated loadings vs. fatigue on a daily basis.

Oh, I know I have it easy. The concepts are new, but the work isn't too bad yet. I wish I could focus on just 2 or 3 classes though. I have 18 hours right now and its hard to stay on top of everything.

 

[dxdexter]

I can remember many times jumping up and down on larger Snap-on and Gray wrenches and never breaking one. Even hooking two large ones together and still no breakage .I had a large Gray wrench that actually had the handle permanently bowed from pounding on it with a sledge and it still didn't break.

Breaking a wrench under "normal" work conditions , or even a little abuse, says a lot about the quality of the tool steel. If I had broken a few wrenches of a certain manufacturer then they would be the last tools I would buy from them.

I remember those days!!! As a music major, 18 hours could easily mean 7 or 8 different classes....


As for all the metallurgy, I find this stuff fascinating when you guys post about it. I don't think I would survive a textbook though....


Oh, and Nissan: even at full price, I think you willy like the Cman Pro deep offset wrenches. This is one tool that Cman got right. My ONLY wish is that SOMETIMES they were a tad longer. Then again, the probably wouldn't fit in most of the locations that I have used them already....

 

[rsanter]

not sure why they are clearance. nothing was missing and the package was never opened. I suspect that they were just not selling out of this store. the sears we have here does not have a full sized tool dept

I will go back a little later and see if the other set is still there and if so I could make it available to someone here

Most tool dealers will tell you that metric out sells inch series tools by thirty to one as the inch series stuff is aging

 

[myers212]

No luck here. They ring up $49.99.

I stopped by my local Sears today. They did not have the offset wrenches on clearance but they did have the 9 pc. SAE pro combo wrenches at 60% off. (Around $23)

When I left, there was one set left. Apparently they had the metrics on clearance too but someone had already cleared them out.

If anyone is interested, the store was in Palatine, IL.

 

[Itzkwik]

No luck here either.
