Part Numbers - Hardware and Utility Parts |
|
 |
Hardware parts (fasteners, clamps, grommets, plugs, fittings and similar items) are
numbered under two different systems:
|
- Standard hardware parts have five-digit numbers (20000-99999) or low-range six-digit numbers
(300000-309999) followed by a "-Sxxx" suffix to designate finish.
Example: 45534-S8
(Grade 2 hex bolt, 3/8-16, 9/15" across flats, 1.00" threaded, 3.00" long,
medium silver zinc plate)
|
- Special
hardware parts use six-digit numbers (350000-399999) followed by a "-Sxxx"
finish suffix.
Example: 378641-S13
(Allen-type screw, 8-32, 35/64" overall, 19/64" threaded w/nylon pellet,
chrome finish)

* Special
Parts were assigned one-up numbers starting in 1944, and thus defy easy
categorization.
For the definitive book on 1955-73 Ford Hardware identification,
order the AMK
Products Guide to Ford Fasteners, which covers more than 10,000
items in a far more readable fashion than Ford's own randomly organized
Standard and Utility Parts Catalogs.
Max Kotlowski's guide also provides photos of each fastener and
correct markings, painfully detailed descriptions of every available
finish, re-finishing instructions for most common finishes and
all the measurements you'd need to purchase over-the counter replacement
fasteners. Many exact, correctly-marked replacements are also
available from AMK,
either individually
or as part of their wide array of
fastener kits. |
