Shear bolts black zinc 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

Black Galvanized Shear Bolts are specialized fasteners designed for applications where security and corrosion resistance are critical. Here’s a detailed description:

1. Material & Coating:

• Material: Typically made from high-strength steel for durability.

• Coating: Galvanized (zinc-coated) to provide corrosion resistance, with an additional black finish (often black oxide or another black protective layer) for aesthetics and extra protection.

• Shear bolts black zinc plated

2. Shear Feature:

• Shear Head Design: The bolt head is designed to shear off (break away) once a specific torque is reached during installation, leaving a smooth, tamper-resistant surface.

• Security Purpose: Prevents removal once installed, making them ideal for permanent or high-security applications (e.g., public infrastructure, electrical panels, traffic signs).

3. Thread & Drive Type:

• Thread: Usually fully threaded for a strong grip.

• Drive Type: May feature a special drive (e.g., hexagonal socket, one-way, or proprietary) to deter tampering.

• Shear bolts black zinc plated

4. Common Uses:

• Construction & Infrastructure: Highway guardrails, bridges, and fencing.

• Electrical & Utility: Streetlight poles, transformer boxes.

• Security Applications: Vandal-proof fixtures, machinery, and public installations.

5. Advantages:

• Corrosion Resistance: Zinc coating + black finish enhances longevity in harsh environments.

• Tamper-Proof: Sheared head prevents disassembly.

• High Strength: Suitable for structural applications.

• Shear bolts black zinc plated

6. Sizes & Standards:

• Available in various diameters (e.g., 1/4″, 5/16″, 3/8″) and lengths.

• Complies with industry standards like ASTM, DIN, or ISO for shear bolts.
