• Mine were hex head and they would not budge and started to thread. Used a nice sharp flat head screwdriver, angled it behind the screw head and tapped it with a hammer until it came away from the back plate a little. This loosened it just enough to remove with a tight fitting flat head. By amateurd - - 26 October 2011

• The heads are posidrive or Philips. Try some WD40 or similar to loosen the threads By linbak - Cheshire - 14 December 2009
