So I've been using this shim stock set in my workshop and it's been incredibly handy for all sorts of projects. You get 30 pieces total with 10 different thicknesses - from super thin 0.001 inch up to 0.01 inch, with three pieces of each thickness. The 304 stainless steel is quality stuff - corrosion resistant and durable, so these will last for years. The 2x6 inch size is perfect - large enough to work with but easy to cut down to whatever specific shape you need. I've used them for everything from automotive work to machinery adjustments to DIY projects around the house. The thicknesses are clearly marked which saves so much time when you're trying to find the right one. The packaging keeps them organized and protected. What's great is having multiple pieces of each thickness - when you mess up a cut or need several shims of the same size, you're covered. The steel is stiff enough to hold its shape but still workable. I've used them for gap adjustments, alignment issues, spacing requirements - they're one of those things you don't realize how much you need until you have them. The quality is solid - no burrs or rough edges, and the dimensions are accurate. If you do any kind of mechanical work, fabrication, or even detailed DIY projects, having this assortment on hand will save you multiple trips to the hardware store. Definitely worth having in your toolbox.
