I put a bit of loctite on the square washer so it stays in place pretty permanently and ran one for commuting for about 10 months/5k miles when I thought my drivetrain was getting noisy. Never had the screw come off and turned out was the Phil cog that was worn and noisy so chain back in use on teh tarck weapon.
The screw on the replacement HKK Vertex I bought came loose daily so I have a KMC link on that instead.
