FillFactor Property
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The FillFactor property exposes the percent of each page used to store index data when the index is created.

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 an Index object is created. It is a read-only property if an Index object references an existing SQL Server index.
Setting FillFactor on index or key creation can cause unintended behavior. For more information, see CREATE INDEX (Transact-SQL).
