what brand are they, they look like 3/8 drive

 

the box says 1/4'' drive. just a no name brand. for the price i dont see why not have a set in the toolbox of the truck just in case

Is it metric or sae?

 

standard.

 

Looks like China has invaded the forums! You know its getting bad when they start using brand names like "American" like the grinder in the other post

 

actually i think thats the company that made the grinders. im sure these are from china but how much of the stuff you have is made in china? think about that for a second half the parts on your vehicle more than likely came from across seas.
