Auxiliary Belt Tensioner Pulley

Forum: 

I have a 2002 F-Speed Sirion, and the adjustment screw on the Auxiliary Belt Tensioner Pulley has snapped.
I can buy the Pulley new, but it comes without the screw.
Belt is making a horrible noise and needs adjusting.
Can anyone suggest a fix or know of someone breaking an F-Speed?
Would be eternally grateful
Thank you
Rod
