I agree. I started my engineering career designing Space Shuttle equipment, and we used them just about everywhere to take care of tolerances between existing and new equipment, different vendor items, and it's just generally good "I know it will fit together" design practice. But when it came to stuff like mounting my cowling, I match drilled through the cowling and into the brackets with the same sise drill bit as the fastener (#8 in this case), then bolted the fixed "nut plate" (anchor nut) to the bracket, match drilled the rivets and installed them, and the resulting fit is perfect. Otherwise I'd find myself chasing the floating part around trying to get things to line up... Mark Langford n5...@hiwaay.net website www.n56ml.com
