Security Screws

Security screws are tamper-resistant fasteners, designed to deter unauthorised removal. Their unique shapes normally require specialised tools for installation and removal, enhancing security measures.

Sentinel are Australia’s leading manufacturer of Security Fasteners and Architectural Fasteners and Trade Warehouse are their preferred online retailer of their full range of security screws.

Due to the extensive range of security screws and restricted supply of some tooling, we do not hold stock of most these products, however when you place your order, stock is dispatched within 24 business hours direct from Sentinel.

Due to this arrangement return orders may be subject to a re-stocking fee imposed by the manufacturer and must be approved prior to return. Tooling is non-refundable so please ensure that you order the correct size tooling. If you cannot determine which size tooling you need, please call Sentinel on 03 5445 3200.
