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.

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.
The Intimidator
- Municipal & Utility Use
- Multi-User Access Points
The Intimidator
- Unique, One-of-a-Kind Keyway Needs
- Highest-Security Applications
- DIY or Same-Day Projects
The Intimidator
Restricted: Proprietary drivers, distributed to authorized users. Control mechanisms unclear.
The Intimidator
Not specified; likely high for automotive applications.
The Intimidator
Not specified; likely higher for custom orders.
The Intimidator
Not specified; likely high due to proprietary keyway.
The Intimidator
Not specified.
The Intimidator
Not specified; automotive focus suggests samples for bulk buyers.
The Intimidator
Proprietary pattern (likely annular or complex geometry), not quantified in variations.
The Intimidator
Controlled, but no details on serialization or verification. Likely distributor-based.
The Intimidator
Primarily conical or cylindrical (lug nut/bolt styles).
The Intimidator
Stainless steel, zinc-plated steel typical for automotive.
The Intimidator
Reusable with proprietary driver; designed for repeated automotive use.
The Intimidator
High: Complex keyway resists standard tools, but less data on advanced attacks.
The Intimidator
Requires proprietary McGard driver; incompatible with standard tools.
The Intimidator
Manual or power-driven with proprietary driver; standard for lug nuts/bolts.
The Intimidator
Moderate: Recognizable as security fasteners, but automotive focus may reduce uniqueness.
The Intimidator
Moderate: Proprietary but fewer variations; risk depends on driver distribution.
The Intimidator
Not specified; likely 1–4 weeks for custom, faster for stock.
