Anti-theft screws, also known as tamper-resistant screws, are fasteners designed to prevent the theft of fixed installations left outdoors in public environments for extended periods. Based on their structure and type, they are classified into two categories: removable and non-removable.
Removable Types
1. Internal pentagonal anti-theft screws
2. Internal star-shaped anti-theft screws
3. Y-shaped anti-theft screws
4. External triangular anti-theft screws
5. Internal triangular anti-theft screws
6. Two-point anti-theft screws
7. Eccentric hole anti-theft screws
Permanent (Non-removable) Type
1. Slotted anti-theft screws (S-type anti-theft screws)
2. Horse-and-carriage anti-theft bolts
Automotive anti-theft bolts are a type of removable anti-theft bolt. The anti-theft bolts commonly found in vehicles typically feature an internal star-shaped design, which prevents theft by utilizing slight variations in the star-shaped teeth. Each set of anti-theft bolts comes with only one unlocking key for the user.
How to Remove Anti-Theft Bolts?
The principle behind automotive tire anti-theft bolts is very simple: the nut is machined into an irregular shape, and it can only be removed using the vehicle’s dedicated anti-theft bolt wrench. Ordinary tools available on the market are ineffective against them. This is the basic principle of their anti-theft mechanism.
When you need to remove a tire, open the vehicle’s tool kit and you’ll find two wrenches—one of which is specifically designed for removing anti-theft bolts. After jacking up the car and completing the preliminary preparations, simply use the anti-theft bolt wrench to remove them.
