Kinmar Removable by Hafren Security Fasteners
The Kinmar® Removable fastener offers a flexible tamper-resistant option for low-risk applications, but its design leaves critical vulnerabilities. The flat top makes it easier to grip with locking pliers or attack with rotary tools, and although the manufacturer claims the driver socket is restricted, it can be found online for around $170—undermining the intended access control. Its use is best limited to low-value or controlled environments where convenience outweighs high security.

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.
