SCREW-NUT-

BGS technic has put together a compact 49-piece set of boring tools for various applications. Neatly organised in a sturdy plastic case. The tools are used to unscrew stripped screws, stud bolts and nuts with defective drive heads. And this is how it works: simply pre-drill the extractors to fix them to the sheared bolt head and unscrew them easily. Sharp helical grooves then "bite" into stuck or defective screws, nuts and bolts and loosen them.

And that's what's in the case for you:
