Alexander Z. ★★★★★

The zinc plating on these M24-3 hex heads has a nice, even finish that hasn't shown any rust after a week in a damp workshop. They seated perfectly into the tapped holes on my press frame with no binding at all.

Lily ★★★★★

Class 8.8 steel feels solid when torquing these down, and the fully threaded design made aligning my machine brackets a breeze. Pack of 20 was enough for the whole job, and the hex heads seated cleanly with a socket.

Carter ★★★★★

The zinc plating on these screws is a nice touch, held up well against moisture during my outdoor equipment repair. They threaded cleanly into the pre-drilled holes without any binding, which saved me time.
