Adam ★★★★★

Used these to mount a motor bracket to some 40mm channel, and the fully threaded length meant I could cut them to exactly what I needed. Class 8.8 held up fine under a decent amount of torque without stripping. Wrench fit was snug on every single one.

Victoria J. ★★★★★

The yellow zinc finish on these M8 bolts looks good and should resist rust well in my shop. They threaded smoothly into existing tapped holes on my press jig without any binding.

David ★★★★★

Fit perfectly on my milling machine table, and the yellow zinc coating gives them a nice corrosion-resistant finish. The hex heads grab the socket wrench nicely without stripping.
