Thanks for the info, Butch. Yeah, that's the sticker on the newer-style ones. I have a couple here with that sticker on them too. I received this info off-list from a good source about the older ones: For a 1/4" stud use 5 +/-1 inch-pounds. For a 3/8" stud use 8 +/- 1 inch-pounds. For a 1/2" stud use 10 +/- 1 inch-pounds. Not much different, really...but not as tight as the newer ones. The smaller transistors must break easier, if I had to guess why they're lower. I thought I'd share in case anyone else is watching the thread for replies. 73, Nate WY0X
