scp and umask setting

How do I make SCP respect umask ? I've tried adding this Subsystem sftp internal-sftp -u 0002 in /etc/ssh/sshd_config and session optional pam_umask.so umask=0002 in /etc/pam.d/sshd Any other things to try? each time scp creates the file as 644 instead of 664 as the umask would suggest
