A Gold Plated Cup Head Shear Bolt is a specialized fastener designed for applications requiring both security and aesthetic appeal. Here’s a detailed description of its key features:

1. Design & Construction

• Head Type: Cup Head (也稱為 hexagon socket cup head 或 button head) with a rounded, low-profile dome shape.

• Drive Type: Typically features an internal hex (Allen key) drive for installation.

• Shear Feature: The bolt is designed with a precisely weakened shear groove just under the head, which snaps off at a predetermined torque, leaving only the smooth shank for tamper resistance.

2. Gold Plating

• 材質： Usually made of high-strength steel 或 不銹鋼 for durability.

• Plating: Electroplated with gold (Au) for corrosion resistance and an attractive finish, making it suitable for decorative or high-end applications.

3. Functionality

• Tamper-Proof: Once installed and torqued, the head shears off, preventing removal without specialized tools.

• Security Fastener: Ideal for permanent or vandal-resistant installations (e.g., public fixtures, machinery, electronics, and automotive components).

• Aesthetic Use: The gold plating makes it suitable for luxury items, jewelry displays, or high-visibility assemblies where appearance matters.

4. Common Applications

• Security panels & enclosures

• Electronics & aerospace assemblies

• Decorative furniture & architectural fittings

• Automotive & marine components

• Cup head shear bolt gold plated

5. Standards & Sizes

• Available in various diameters (M3, M4, M5, etc.) and lengths.

• May conform to DIN, ISO, or ASTM standards depending on the manufacturer.
