The Screw Of What Material Is Firm, Want That Kind Of Firm Strength Is Very Good, Won't Break Most

In fact, you should provide the occasion. Talking about screws without the occasion is like grading an athlete without a track.

I've been making screws for many years, and I rarely see them break.

General screw fracture, most of which is due to hydrogen embrittlement, fracture generally appears in the screw head. As long as the electroplating process, hydrogen embrittlement treatment, generally can solve this problem.

If you have really high screw requirements, you can use 316 screws, or titanium alloy screws.
