Review on Uxcell M4X40Mm Machine Stainless Fasteners by Everette Jean

These screws were a major disappointment for our industrial and scientific team.Using this product, our team found that the threading was inconsistent and often stripped easily, making our project more difficult and time-consuming. The only positive thing we can say is that the price was decent, but it wasn't worth sacrificing quality for a lower cost. We would not recommend these screws for any professional or scientific project..
