OMG I frikkin hate McMaster's navigation and comparison options. Their standardization is even quite sloppy, i.e. some screw vendors apparently include the head height in the length spec, and you don't find this out until your box of #2-56's show up for your precision fixture and are ~1mm too short.

I always tolerated McMaster's crappy UX as just a symptom of how MEs are willing to tolerate more shaggery than CS types.

Go to the product detail and they show precise measurements and often CAD models of the part.

IOW the "principle of least surprise" is not even expected to be observed in the ME world. We're talking about a product category -- machine screws -- that has been full standardized for over 100 years. And when McMaster still manages to crap the bed, the rebuttal is "why didn't you load up the CAD model and verify things yourself?"
