#8-32 and #10-32 PEM nuts both use a .25 or smaller hole that they are pressed into. If there is ever an issue where they get stripped/pushed out, they can be replaced with a 1/4-20 bolt and nut. We've been using them for two years now on critical drive train/chassis sheet metal components, and as far as I know have yet to have one strip or fail.

Instead of using a master link, the DarkSoul chain break is used is used to drive the pins [partially] out of the roller chain, put two ends of the chain together, and then drive the pin back in. There is no master link because any link can be the 'master link'.

It's too bad about the out of stock issues; the one we picked up back in December has proven to be one of our most useful tools. If the DarkSoul chain breaks are no longer in production, it's not a very difficult device to reverse engineer and machine yourself on a milling machine.
