The PROLOK SCROLL NUT is a patented unique high security nut, almost impossible to remove without the matching tool and suitable for medium to high torque applications.
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
