Review: En mi taller de casa lo uso para identificar con facilidad tornillos
Review: I do a lot of DIY engineering and mechanical projects and I waste a ton of time hunting the right size nut, screw, bolt, etc. This simple, well-made sizing tool is one of the absolute best aids I have ever bought. I even take it with me to Home Depot and Lowes to make sure I'm getting the correct product size...no returns or multiple trips for mis-matched sizes. Thank you to whomever created and sells this product.
