Recessed Lighting rough-in

Been to my electric supply house and have my 18 air-tite recessed lights. I noticed the wiring connection box has screwdriver knockouts. When I run the wire through these holes, is there a bushing that should be placed on the wire, do I have to use a cable clamp or is there something else that works. I plan to staple all wires within 12" of the light and every 4 feet along the ceiling joist.

Please pick up one or more books on electrical wiring. You will learn many things from reading it. There are several very good inexpensive books out there.

To answer your question,, yes, you need a clamp to attach your wire to the junction box.

Actually, most recessed lights have integral clamps. If the knockout you are referring to is roughly the same size as an NM cable, and has metal plate inside the box under it, then it is an integral clamp and can be used without an NM connector. If it is a full size (1/2") knock out, then you need a connector.
