New Revision F for MIL-HDBK-57, Listing of Fastener Manufacturer’s Identification Symbols

MIL-HDBK-57 Revision F has just been released.  The handbook, titled “Listing of Fastener Manufacturer’s Identification Symbols,” replaces the previous edition MIL-HDBK-57E from 2008.  The 252 page handbook is a compilation of the identifying symbols of fastener manufacturers as provided by the manufacturers themselves.

This revision contains the names, addresses, and the symbols of all fastener manufacturers whose identifying symbols were received by November 30, 2006.  Additionally, each manufacturer who was listed in a previous revision of this handbook was contacted to confirm the accuracy of the published information.  The listing is also annotated to indicate both those manufacturers who have and have not responded to confirm or update appropriate information.   Information about manufacturers who have not responded is still maintained in this latest revision.

The document contains both an alphabetic index of manufacturers (Index A) and a listing of manufacturers indexed by their identification symbol (index B).  It also contains a registration form and information on how to be included in the listing in the future.

MIL-HDBK-57 defines a manufacturer as a source which substantially makes the supplies, either by hand or machinery, out of raw materials. The term “fasteners” refers to those threaded items included in Federal Supply Class (FSC) numbers 5305 – Screws, 5306 – Bolts, 5307 – Studs, and 5310 – Nuts.
