AN machine screws begin
at AN500 and continue through AN526. In addition there
are structural screws under NAS 220-3, 623 and MS27039, plus non-structural
screws MS35206/7, MS51957 as well as the brass instrument screws MS24693 and
MS35214.
AN machine screws are described by a double dash number; the first
part number indicates screw size (#4, 6, 8, 10, 1/4, etc.) while the second is
the length in nominal 1/16ths of an inch. Substituting the letter B or C for
the first dash designates brass or stainless steel material. An R following the
first dash number indicates phillips head instead of slot head. |
Example: AN
507C 6R10 would be a #6-32 100deg Counter sunk head screw, stainless steel,
5/8" long with phillips head.
AN 526-10-20 would be #10-32 Truss head plated
steel screw with slot head, 1 1/4" long.
Although most part numbers are
unique as to pitch (UNF or UNC) some are available in both fine and coarse
thread (AN 507, 509, 525,526). But by far the most commonly seen pitches are
UNC for sizes 4, 6 and 8, and UNF thereafter. On the rare occasion a #8 UNF
(8-36) is seen, it's dash number will be followed by an F. |

What size is it?
We find
that most people can identify fastners by eye in the fractional sizes, many
seem clueless in the smaller numbered sizes. Here is a quick reference: |
