Lock-Out by Tanner
Lock-Out® screws offer a significant step up from standard tamper-resistant fasteners, featuring a patented oval center pin drive and high torque resistance. The smooth, button-head profile is also a good deterrent against gripping tools like locking pliers. However, the limited number of unique drive patterns may reduce their effectiveness in high-risk applications or against targeted threats.

Shear Bolts by Hafren Security Fasteners
The Shear Bolt uses a breakaway hex head that snaps off at a calibrated torque, leaving behind a smooth, ungrippable surface. It's a simple and effective design for creating permanent installations. Once installed, removal typically requires drilling or destructive force. However, the initial install is limited by access to torque tools, and over-tightening or under-tightening can reduce performance.
