Review: Extremely happy with these bolts. Reviews had a couple horror stories, but as always figured I'd give it my own spin and see what happened. I was using these to replace/upgrade fog light mounting screws for a 1G DSM/91 Eagle Talon, and the results were extremely satisfying. They were packaged awesomely, and bolts were shiny and coated nice. They claim to be stainless, and as they are brand new I cannot testify to their rust resistance or longevity, but honestly they feel solid and nice. Much better than the phillips head "bolts" they were replacing for sure. A size 4 Hex bit on a ratchet wrench makes them easy to remove or tighten. Overall I honestly don't see how, unless you got a bad batch, you could strip the "head" of these bolts. Don't use them to tighten something that needs more torque than the bolt can handle. For my situation, it was ideal. Would buy these or any other fastener from this "company" iexcell again. Regarding the pictures: The first picture is a "before" of the brand new phillips head screws that were used and already on their way to stripping, and the second is the brand new iexcell bolts. Love it!

## Questions & Answers

**Q: what size allen wrench / driver do i need with this?**
A: 2.5mm

**Q: What's the thread pitch?**
A: This is why I hate the multiple-choice product listing on Amazon. Many different items with different sizes as options. People asking questions are not always asking about the same size or style that I am looking at. It's the same with the reviews.

**Q: Is the thread size and pitch M5 - 0.8mm?  Will it fit in the threaded holes used for a bicycle water bottle cage?**
A: The thread size and pitch are definitely M5-0.8, but as to whether it will fit the threaded holes for a bicycle water bottle cage, I have now idea. Your local hardware store might have a thread gauge to assist you.

**Q: How many inches in length is the 50mm?**
A: 1.97 inches  (50mm/25.4=1.97 inches)
