Tamper Proof Hex Key

The Tamper Proof Hex Key is a precision specialty tool designed to install and remove tamper-resistant fasteners used in secured assemblies. By matching the geometry of security fastener heads, this tool helps prevent unauthorized access while allowing controlled servicing by authorized personnel.

Tengco supplies tamper-proof hex keys engineered to match specific customer fastener designs, ensuring proper engagement, reduced fastener damage, and consistent torque transfer. These tools are commonly included in OEM tool kits or maintenance sets where secure fastening is required.

Tamper-proof hex keys are manufactured from hardened alloy steel using precision machining or cold-forming processes. After forming, the tools undergo heat treatment to achieve the hardness needed for long service life and resistance to rounding or wear. Protective finishes such as black oxide improve corrosion resistance and reduce surface friction during use.

• Designed for tamper-resistant hex fasteners
• Precision fit for secure engagement and torque control
• Hardened alloy steel construction for durability
• Heat-treated to resist wear and deformation
• Black oxide or protective finish for corrosion resistance
• Custom geometries available for proprietary fasteners
