Remarks

Microsoft® SQL Server™ primary keys are supported by unique indexes built on the columns participating in the PRIMARY KEY or UNIQUE key constraint. For the Key object, the FillFactor property only has meaning if the Type property reports SQLDMOKey_Primary.

FillFactor can only be set when creating an Index object. It is a read-only property when an Index object references and existing SQL Server index.

Setting FillFactor on index or key creation can cause unintended behavior. For more information, see CREATE INDEX.
