Excellent Strength

Used these for a suspension project. They held torque perfectly without stripping. Very satisfied with the 10.9 grade quality.

Solid Hardware

Good for general machinery. Wish they came in a plastic case instead of cardboard.

Good Value

The bolts are solid but the packaging was a bit crushed upon arrival. Product itself is fine.
