This set of M10 machine screw nuts is everything you could want in a fastener and more. The 18-8 stainless steel is not only durable but also rust-resistant, ensuring that the nuts will withstand whatever job you throw their way. Plus, the 1.5mm pitch makes them easy to install quickly and easily. But what really sets this set of nuts apart is their square shape. This unique design makes them easy to grip and manipulate, ensuring that you can tighten them without any frustration or fumbling around. And with 15 nuts included, you'll have plenty to use on all your projects. Overall, I couldn't be happier with my purchase. These M10 machine screw nuts are simply perfect in every way. Highly recommended!
