The partially threaded shaft makes seating these into jigs so much easier, and the zinc coating handles shop moisture without a speck of rust so far. I've used them across three projects now and every single one torqued down clean without a stripped head in the batch.

The 12.9 grade is no joke—these bolts took a serious load on my jig fixture without stripping or flexing. The partially threaded design gave me the grip I needed.

Used these for a jig I was building and the partially threaded design made alignment much easier. The hex socket drive gripped perfectly without any stripping, even under decent torque. Exactly the precision I needed for the job.
