Which old part number correlates with what Crownsert® part number made of 17-4PH Stainless Steel?
This cross-reference helps identify which old insert part number corresponds to the matching Crownsert® 17-4PH stainless steel threaded insert. It is intended for maintenance, repair, purchasing, and replacement situations where an older SR or SRW reference must be converted into a current Crownsert part number.
The tables below cover Crownserts made from 17-4PH stainless steel, Cond H1025 per AMS 5643. Both locking and non-locking versions are listed, and the heavy-duty SRW references have been added where they match 17-4PH Crownserts in the current database.
17-4PH Stainless Steel Crownserts — old part number cross-reference
Start with the old part number in the left column, then use the Crownsert part number in the right column as the current equivalent. The Crownsert code links directly to the corresponding product record, and the old reference is also linked because these supplier-reference records are present in the database.
In general, CS and CSH indicate non-locking Crownserts, while CSL and CSHL indicate locking Crownserts. The H series identifies the heavy-duty version. For 17-4PH stainless steel, suffixes such as P, SP, and AL identify different finish or coating variants where those records exist.

What is the difference between SR and SRW old references?
SR references are used here for the standard Crownsert series. SRW references are used for the heavy-duty equivalents, which correspond to the CSH and CSHL Crownsert families.
