I remember using this when I was a trainee machinist way back in 1962 . It was perpetually kept in my top pocket and proved invaluable - everyone in the workshop had one. I don't know if the contents have changed much over the years, but the black and yellow cover design hasn't. I'm retired now but still find this little book worth its weight in gold - a must have, even if you are just drilling & tapping.

Back in the 1970s when ~I was an industrial engineer, some of the tap and die detail booklets I got from manufacturers like Dormer and Goliath were more logically organised than the Zeus book. But for the amateur engineer, the Zeus book seems the only one left. The main issue I have is that tapping and clearance drill sizes for non-metric threads are shown in a separate table to what might be called the identification table. The latter contains some less useful details such as crest/flat and effective diameter values which would be better in the separate table. This is different to the metric threads, where tapping and clearance sizes are included in the main table. There is no longer any detail table for BA threads, just tapping drill sizes. I think this is inferior to the Zeus book I remember from the '70s. It's useful mainly because it has no competition. It's what's left, so we have to use it.Read full review

I've used Zeus guides over the years. Lots of useful information in a compact form.

Strong, wipeclean, pocker sized, logically laid out, this book is easy to use at the bench with oily hands. I wish I got one before, much handier than big expensive thread bibles or googling stuff.
