Titanium Clip Screws
These 6al-4v titanium screws are the best available. The low profile button head stays out of the way and is much less prone to snagging things. The torx socket is virtually indestructible. If you are able to damage one of these using the proper driver, I'll congratulate you. Sold in sets of 2.
Please note that all flashlights come with these titanium screws already so you don't need to order these unless you'd like an extra set.
