The PROLOK– CLUTCH HEAD range of screws were probably the worlds first security screw, they have a raised head design for a superb visual effect and only operate in a clockwise direction, which is ideal for permanent fixtures
A standard flat-blade screwdriver can be used for installation, so no requirement to purchase additional tools
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.
Tooling is NON-REFUNDABLE we therefore advise you contact Sentinel prior to making your purchase to confirm you have made the correct selection - 03 5445 3200
