good for missing screws on machines

I loved the Screws assortment kit; I think it will be a handy thing to have around the house to help in facets repair. definitely I would recommend to all handy men.

Great for all my RC models

Ok.

This is the most impressive assortment of parts I've ever received. A lot of thought actually went into this. The small parts are bagged to keep them separated, and the dividing panels are molded in place so there is no change of the parks mixing because a divider popped up. Nice inclusion of set of Allen wrenches, so some are always on hand.

This is a great selection of metric grub/set screws. They require Allen wrenches to tighten and loosen; much better than using a straight-slot screwdriver. I needed a metric set screw for a Powermatic tool, and instead of just purchasing what I needed immediately, I ordered this very complete set. Now when I run into that problem again, I'll have the solution immediately available. Much better than waiting for the part to come in, or making a special trip to a big box store hoping they have what I need in stock.
