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:

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

• コーティング： 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:

• 耐食性： 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.
