Amazon.com Industrial & Scientific: screws, and nails
Amazon adds an Industrial and Scientific section! Lots of good bits for the budding inventor who can’t find parts locally.
Just how small is our stainless-steel hypodermic tubing? It comes in diameters as fine as 0.00425 inches–the width of a thick human hair. We have dozens of sizes, several lengths, and two types of stainless, so you’ll find a combination that’s right for practically every application. It’s perfect for industrial applications such as precision dispensing, fiber-optic guides, and sampling probes, and for use in such medical devices as laparoscopes and needles.
