lock nuts with a backing plate or even large fender washers will work just fine. the Teflon nuts are just nuts with Teflon on the end. I mounted my tracks on my boat with just ss screws. I wanted to make sure they would hold so I put 2-rod holders out 90 degrees and grabbed on. I lifted my 250# weight and jerked as hard as I could and it held just great. I used riggers in the tracks once but tied them to the boat just in case. i removed the tracks the other day to put them on another boat. the screws were still as tight as they were when I installed them a few yrs ago. and I wouldn't use riggers on them often without using bolts with Teflon nuts with some type of backing plate. i use my rod holders for running 3 lite bite slide divers per side.
