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.

The Intimidator by McGard
The Intimidator offers solid tamper resistance with proprietary key patterns and regional key code tracking. However, the exposed head shape makes it easier to grip with common tools like locking pliers, which may be a concern in higher-risk environments. While the drive pattern is proprietary, it isn’t unique per customer. It’s still a practical choice for shared-access applications like municipal or utility use—but not the strongest option for physical tamper resistance.
