The best screws I have found are the grade 12.9 hard steel screws that you can find at a few hardware suppliers around the globe. The link below shows you just some of the screws I now use, and I have yet to strip or break one of these. If you want the best results, then you have to use the best tools and hardware to hold your expensive toy together. Lito turned me on to BoltDepot.com a couple of years ago, and I have not been disapointed yet. I have about $1000 in hardware from them in my R/C storage bins, and I have changed out everything on my trucks using their 12.9 grade screws. Everything looks clean, and everything works the way it should.

It was a tonys which I didn't expect. I probably cranked it to hard I'm guessing or I got one in a million that was bad. Every now and then a weak part comes along but not often. I broke one one the bolts that mounts the bulkhead to the chassis. When I worked on semi trucks years ago using the big nuts and bolts we did grade 8 was a big thing in the shop we worked in. They took the brute force. I wonder how the grading system works with the rc screws, bolts, etc.
