Titanium screws for Gilles chain adjuster blocks, Honda SP2

I’ve made some titanium screws for Gilles chain adjuster blocks for a Honda SP2. They are retained in place by a roll pin that sits in the groove under the head, but the OEM ones snap as its only 4.7mm dia at the bottom of the groove, so we’re trying titanium ones for the strength as well as lightness. But they are snappable in titanium, i managed to bust one off at the groove when i tried to run a die down the threads when i hadn’t screwcut it deep enough.

The washer is an M22 axle washer.
