Good quality, tight packaging

The bolts are great grade 12.9. Only issue was the bag was sealed very tight and hard to open safely.

Reliable fasteners

Bought these for a machinery repair. They hold up well under vibration with the spring washers.

Excellent strength for automotive use

These bolts are genuinely high strength. Used them for my suspension setup and they torqued down perfectly without stripping.
