#1 The set screw on my Kwikset 917 has fallen out, and the handle won't stay on. Is it possible to get a replacement set screw? Is there a particular part number to order?
The set screws are reverse threaded and are pre-installed in the lever shafts. On the exterior shaft, the set screw is backed in from the bottom up, and if you look at the top, you will see the backside of the set screw. To tighten or loosen the lever, first, open the door and insert the key into the cylinder to unlock it. Next, insert the 3/32 Allen wrench into the hole on the bottom of the lever, and rotate the Allen wrench to tighten or loosen the lever.
