Just found out most of my coax ends are probably garbage

I was at a supply house in Cleveland last Tuesday picking up some fittings and an old timer behind the counter asked me what I used for compression. I told him my Klein ratcheting tool and he just shook his head and showed me his collection of rejected ends from other guys he knows. Turns out a ton of those cheap generic compression connectors you grab in bulk packs have way too much variance in the inner diameter. He pulled out a caliper and measured three different ones from the same box and they were all off by like 0.005 inches. I went home and checked a handful of my recent jobs and I bet I got at least 10 percent that are gonna fail within a year. I never even thought to measure them before. Anyone else ever check their connector tolerances or just trust the package?

That quote about 'off by like 0.005 inches' got me thinking. My buddy Mike does commercial installs and he had a whole spool of coax that kept giving him weird signal loss issues. He finally borrowed a micrometer from his neighbor who works in a machine shop and found every connector was undersized by a hair. He ended up tossing a whole box of 50 ends, said he couldnt trust a single one after that.

Honestly @fiona_young, that sounds like overkill to me. I get that signal loss is annoying but tossing 50 ends just seems like a waste of money for something you could've probably fixed with a barrel connector or two.
