The screws (3/8-16 x 1) I received are of excellent quality. The maker's mark on them is RAAJ, they are made in India and are way better than Chinese junk. The alloy designation/property of F593C as shown in the images is ideal for many applications requiring the use of stainless steel bolts. F593C is slightly stronger than some of the other stainless steels, so I prefer it. ***** STAINLESS STEEL LUBRICANT IS REQUIRED! ***** I use either SuperLube or caliper grease (waterproof grease) depending on what I'm using the bolts for. Wheel bearing grease works too, and I've used it occasionally. Stainless steel has characteristics and properties that are different from other steels commonly used to make screws and therefore needs to be handled differently. Don't expect a liquid spray lube to work. Stainless steel needs grease on every bolt and nut. Without lubrication, they eat and eat often. I've bought a lot of things from Bolt Dropper and they've worked really well so far.
