How do I position the Stop Collar on my Kreg Jig® K5 to accommodate different material thicknesses?

Place the stop-collar setting block on the jig base in front of the drill guide. Slide the step bit into one of the drill guide bushings and drop the pilot tip in the hole in the block that corresponds to the length of the screw you’ll be using. With the step bit shoulder resting on the block, slide the stop collar onto the drive-end of the bit so it rests on the drill guide. Then, tighten the stop collar set screw with the included hex wrench.
