Please note that due to the extensive range of security screws and restricted supply of some tooling, we do not hold ANY stock. When you place an order, we order in from Sentinel, who will ship directly to you (usually by express airbag) 

Due to this arrangement the RETURN of screws may be subject to a re-stocking fee imposed by the manufacturer.
