Midwest Industries Stock Wrench
Quality product, great service and fast shipping.
Works great. exactly what I am looking for in a stock wrench.
Simple, cheap, and does the job.
by Gary Hallgren
Well made with good fit.The stamped steel wrench has been de-burred and leaves no marks on the nut.
Well Made Tool!
Works as expected, long enough to provide good leverage!

I didn't need a full armors wrench just something for the castle nut (cheap enough to justify over using a punch to set the castle nut). While I didn't use the torque wrench cutout, I will now that my build is confirmed working. Wrench worked great!
Gets the job done ... barely.
by Neth -
Gets the job done but only by hand, which is difficult considering its small size and thinness. Does not properly fit a 1/2" torque wrench. The hole is way too big at .65" from flat to flat and strips once you apply a little force. This tool is the bare minimum to get the job done. Get a higher quality one if you plan on more than one build.

Works great, functions as it should. Couldn't beat the price
NOT FOR USE WITH TORQUE WRENCH
by Alexander -
The description lists this tool as accepting a 1/2" torque wrench, but as others have pointed out, the slot in the wrench is much too big to properly fit 1/2" drive. Other tools with this design label that slot as an A1/A2 flash hider wrench, which is what it actually is. This wrench is only to tighten by itself, not in conjunction with a torque wrench. Probably would be okay for the flash hider, but since it's impossible to measure torque for the castle nut, it's not useful for that.
<br>From PA: We're very sorry for the confusion and we'll get our page updated.
