Cup head shear bolt gold plated

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

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 (also known as a hexagon socket cup head or 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

• Material: Usually made of high-strength steel or stainless steel 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.
