With tiny little bolts to keep the stem tight to the steerer.
Pitch your bike or crash hard, and the headset gets loose. Try to torque the bolts too tight, they strip right out. I can't do a headlocker, I like my brake cable through the steer tube. After ripping the threads out of several mtb stems, I decided to go to a bmx stem, with REAL bolts in it.
I bought some 22.2mm bars, but didn't like the shape... so, I thought maybe I'd drill and tap my Azonic stem for bigger bolts. Not much room for that, so I measured my mtb bars and found 25.4 = 1". I put the stem in my mill, clamped the top down on some spacers, and bored it out to 1"!
Now my bmx stem fits my MTB bars PERFECTLY.
