Tamper-resistant bolts and nuts are specialized fasteners designed to prevent unauthorized removal or tampering. They are commonly used in applications where security, safety, or vandalism prevention is critical. These fasteners feature unique designs or mechanisms that make them difficult to remove without the proper tools or knowledge.

Key Characteristics:

1. Unique Drive Designs:
   • Tamper-resistant bolts and nuts typically feature non-standard drive designs that require a special tool or key to install or remove. These drive patterns are not common in standard tools, which makes it difficult for unauthorized individuals to manipulate them.
   • Examples of drive designs include:
     • Pin-in-Hole: A central pin inside the bolt head that requires a corresponding driver.
     • Hex with Pin: A hexagonal shape with a central pin, preventing standard hex drivers from working.
     • One-way or Reverse Thread: These bolts can only be tightened, not loosened, without a special tool.
     • Spanner or Snake-Eyes: Two small holes opposite each other in the bolt head or nut, requiring a specialized tool.
2. Corrosion-Resistant Materials:
   • Many tamper-resistant bolts and nuts are made from high-strength, corrosion-resistant materials like stainless steel or coated with anti-corrosion finishes, ensuring durability even in harsh environments.
3. Security Features:
   • Often designed to resist tampering with tools like wrenches, pliers, or screwdrivers. Some designs include additional features like locking mechanisms or captive nuts, which help to further secure the fastener.

Tamper-resistant bolts and nuts are essential in environments where standard fasteners could be easily removed or compromised, providing an added layer of protection and peace of mind.
