Good Value
Solid screws but the head strips easily if you use the wrong driver size. Otherwise good quality.

Excellent Hardness
Used these for engine mounts and they held up perfectly under high torque. The 10.9 grade is legitimate.

Perfect for heavy machinery assembly. The tri-lobular design makes installation much faster.
