The following pages are to help you figure out how your 1980 - 86 Ford truck was meant to go together, and what fasteners were used to keep it together.

Ford used a variety of fasteners on these trucks, both metric and SAE.  And many times in the parts catalog a cryptic number is given for the fasteners, like N623332-S2 or 55914-S36.  But, there are a couple of things to note from the format that was used.  First, the letter prefix ahead of the number is significant, and an "N" means it is a metric fastener.  And numbers w/o the prefix are SAE fasteners.

Second, the suffix, meaning the "-SX" tells us what finish was used on the fastener.  Ford's 2004 Standard and Utility Parts Catalog has a table showing what the finish suffix means, and I've included three versions of it below.  First is a table I've created from the catalog:

Next is a conversion I've done into PDF, and you can peruse it easily.  However, you can also download it, which allows you to search the contents should you need to do that.

Last is a snippet from the catalog.  It is easily viewed, but it can be a pain to navigate.
