Gold-plated hexagonal shear bolts are specialized fasteners designed for applications requiring both security and corrosion resistance. Here’s a detailed description:

1. Material & Construction

• Base Metal: Typically made from high-strength steel or stainless steel for structural integrity.

• Plating: Electroplated with a layer of gold (often a thin micron-level coating), providing corrosion resistance and a decorative finish.

2. Head Design

• Hexagonal Head: Features a six-sided (hex) head for tool engagement (e.g., hex wrenches or sockets).

• Shear Feature: The head is designed to shear off at a predetermined torque, leaving a smooth, tamper-proof shank behind. This prevents unauthorized removal.

3. Thread Type

• May have machine threads (e.g., metric or UNC/UNF) or custom threading depending on the application.

4. التطبيقات

• Security Uses: Ideal for tamper-resistant assemblies in public infrastructure, electronics, aerospace, or military hardware.

• Aesthetic/Functional: Gold plating offers both corrosion protection and an attractive finish for visible components.

5. Advantages

• مقاوم للعبث: Sheared head deters disassembly.

• مقاومة التآكل: Gold plating protects against oxidation.

• High Strength: Base material ensures durability under stress.

6. Common Sizes

• Range from small (M3, M4) to larger diameters (M12+), with lengths tailored to specific needs.

7. Standards

• May comply with industry standards like DIN, ISO, or MIL-SPEC for shear bolts.

These bolts are used where permanent, secure fastening with added environmental protection is needed. Let me know if you’d like specifics on sizing, torque values, or alternatives!
