Just for some adjustable pin love, I'll say that for a newbie they're great. I used them on several of my first attempts at restorations and they do the job easily. They're also useful when doing mock ups. I always hand tightened mine and never used Loctite.

That being said, I posted a few threads detailing my recent endeavors in peening and now that I have the materials and am comfortable with the process, I'm replacing all my adjustable pins with peened rod.
