1.) Simply align the rectangular 'wing' (or flange?) that's sticking out on the replacement Safe-T-Tip part, with the little open rectangular-shaped slot that's located at the nose-end of the chainsaw bar.
2.) Insert the replacement Screw (which lacked the advertised "Washer" portion of 'eReplacementParts' listing) through the corresponding (i.e., ONLY) hole in the chainsaw's bar that it could possibly go through.
3.) Tighten the aforementioned Screw with a wrench.
*Note: If you want to apply a screw thread tightening agent - such as "Loctite" to the Screw's threads, that would be advisable considering the amount of vibration that the chainsaw bar undergoes during normal use. Additionally, there were enough threads of the newly purchased Screw, that were sticking out of the other side of the Safe-T-Tip after I screwed it in, upon which to install / fasten a nut as (a sort of 'backup'). This, in order to further insure that it doesn't back out and get lost during use.
