Customer Reviews (4.8 / 5 · 5 reviews)

Leo W. ★★★★★

The black oxide finish is a nice touch—it gives them a uniform look and should resist surface rust during storage. Threads cut cleanly into the tapped holes on my precision assembly, and the 12.9 hardness gives me confidence torquing them up properly.

Kevin ★★★★★

Used these in a jig I was building at work and the 12.9 grade held torque perfectly without any sign of stripping. The partially threaded portion made alignment easier than fully threaded bolts would have.

Nicholas F. ★★★★★

Black oxide finish looks sharp and the hex socket drive seated perfectly on my wrench—no wobble at all. These M27s handled the jig assembly torque without a hint of flex, so I’m glad I went with the 12.9 alloy steel for this job.
