Help Reading the PET, Hardware Specs Options

[NARP74]

Trying to get some pedal board hardware sorted. The PET calls out part number 900 067 009 02 M6 x 15 pan head screw. When I talk to other people or look at another car I see a socket head bolt, my description.
Are the descriptions in the PET generic or is that just the name for them, or is it lost in translation?
Does any documentation have the actual correct names and pictures?

Just trying to figure some things out as a learning experience, not a 100 point restoration project.

And I should clarify my statement about the accuracy of the PET. From what I have seen, the number of errors in the PET is large, but but the percentage of errors against the total number of parts listed is not enormous. If I were to take a WAG, less than 5% (IMG:style_emoticons/default/confused24.gif) ? That doesn't seem bad considering the number of parts to catalog, most certainly a time crunch, and would have been using a mainframe computer (quite likely using punch cards) or no computer at all. I'll cut them some slack, and like Mark said, sweating the small stuff wouldn't have been good for business.
