Review on Enhanced Efficiency with Machine Phillips B18 6 3 Threaded Threads by Robert Rick

I have ordered these screws in various lengths from this customer and they have all been great. Decent product at a reasonable price. I use them to attach 3D printed parts together, so I can't say much about their durability under extreme loads or environmental conditions. The addition of the CAD drawings of the screws is a nice touch as I was able to design them before receiving the product.
