Fast delivery

Arrived quickly and packaged well to prevent rust. The protective oil coating was just right.

Accurate shoulder length

Critical for my alignment project. The shoulder length was consistent across all bolts in the pack.

Perfect for mold bases

Used these for a new stamping die setup. The shoulder tolerance is excellent and the hex socket did not strip under high torque.

High quality steel

Very impressed with the hardness. These are genuine 12.9 grade and hold up well in high vibration environments.
