Fastener part numbering system explained:
The last 2 digits (XX) of the 4 digit fastener part number prefix (40XX-12345-12) indicates the standard stud size of the bolt or screw. For example, part No.4006-01030-12 indicates a No.6 stud diameter (.138") fastener.
The 2 digit part number suffix for bolts and screws (-12, -04, -16, etc) indicates the number of 1/16" length increments of the fastener. For example, part No.4004-01003-04 indicates a screw that is 4/16" long or 1/4" long.
The middle 5 digits describe the fastener head style or other features.
