The Well-Nut threaded insert is a flanged neoprene bushing with a brass machine nut molded into one end. Tightening a conventional machine screw threaded in the brass nut causes the insert to expand, making a secure fastening. Uses #10-32 machine screws (not included).

easy install,, hold great don't leak, as good as it gets
do the job they were intended to do. I also use them inverted as a temp way to hold work decks to cockpit.
This is a great product. I only wish the description clearly stated that if you use the 1" well nut, you need to get the 1-1/4" bolt. I mistakenly got the 1" well nuts and the 1" bolts (thinking they were a match set) only to find that the bolts were too short once you added whatever you are putting on the kayak. Otherwise, they work great!
Item worked great and as advertised. Great quality. ACK customer service is outstanding and second to none.
