A quick trip to the fastener store (Fastenal or good hardware) with your set screws and have them matched with the ones having the nylon tip or plug in the threads. They do not work loose.

the shellplate doesn't have any set screws. It threads into the top of the ram and stays tight from a friction fit.

There are fasteners available that have a nylon "plug" molded into the threads near the end.

Nylok is the brand name.

It would be very unusual for the shellplate bolt to loosen, as the shellplate rotates in the clockwise direction, as way the bolt tightens. A drop of blue loctite is the correct response. the shoulder of the bolt stops against the top of the shaft, preventing extreme overtightening. Unlike the RL550 and XL750/650 loaders, there is no set screw to lock the shellplate olt in place, since it canot tighten enough to prevent the shellplate from rotating.

also could try a wrap or two of Teflon tape
