Expansion Anchors With Yellow Zinc 3Pcs/4Pcs Shield

Yellow Zinc Expansion Anchors with Shield - Reliable Fastening Solutions for Concrete Surfaces

Our premium yellow zinc expansion anchors are engineered for superior performance in securing heavy-duty fixtures to concrete, brick, and masonry substrates. Featuring a robust assembly that includes a head Bolt, expansion tube, flat washer, Expansion Nut, and Hex Nut, these fasteners provide exceptional holding strength across diverse construction applications—from residential projects to industrial infrastructure like dams, bridges, and nuclear facilities. The galvanized finish ensures corrosion resistance, making them ideal for both indoor and outdoor environments.

These anchors operate on a proven mechanical principle: when tightened, the threaded screw pulls inward, causing the metal sleeve to expand outward against the surrounding wall or base material. This creates a powerful friction grip that prevents withdrawal under normal load conditions. Unlike simple dowels, this design effectively fills voids in drilled holes, maximizing anchoring reliability without relying solely on adhesive bonding.

Key Features:

• Available in 3-piece or 4-piece configurations (with or without washers)
• Yellow zinc coating offers enhanced rust protection compared to standard black finishes
• Includes multiple anchor styles such as O-Type Shield, C-Type Shield, Shark Fin Sleeve, Flange Nut, and Hex Bolt variants
• Designed for easy installation using basic tools—no special equipment required
• High tensile strength suitable for structural steel connections, embed plates, and mounting hardware

The versatility of our Expansion Anchor system allows users to select the optimal configuration based on substrate type, load requirements, and environmental exposure. For instance, the O-Type Shield Anchor excels in hollow walls where consistent pressure distribution is critical, while the Hexagon Nut Sleeve Anchor provides maximum torque resistance in high-vibration settings. Each variant undergoes rigorous testing to meet international standards for durability and safety.

Common Applications:

• Securing air conditioning units, awnings, and solar panels to concrete slabs
• Mounting handrails, guardrails, and safety barriers on industrial structures
• Attaching structural steel elements to reinforced concrete foundations
• Installing signage, lighting fixtures, and utility brackets
• Fixing machinery supports and equipment frames in commercial buildings

Customer Feedback:

Users consistently praise the ease of installation and long-term stability of our yellow zinc expansion anchors. Many report that even after years of exposure to weather extremes, the fasteners maintain their integrity without loosening or corroding. One contractor noted, “These anchors saved us time during a large-scale renovation project—we didn’t need to re-tighten any bolts after the first month.” Another user highlighted the value of having multiple configurations available in one product line, enabling quick adaptation to varying job site needs.

Frequently Asked Questions:

Can this anchor be used in ceiling installations? While it's effective for most vertical surfaces, it’s not recommended for ceiling-mounted items like fans due to potential vibration-induced failure. For overhead applications, consider specialized ceiling anchors designed for dynamic loads.

What makes yellow zinc different from other coatings? Yellow zinc provides better corrosion resistance than plain steel or black oxide finishes, especially in humid or coastal environments. It also offers improved aesthetics without sacrificing performance.

How do I choose between 3-piece and 4-piece models? The 3-piece version typically includes the bolt, nut, and shield only—ideal for simpler installations. The 4-piece model adds a flat washer, which helps distribute load more evenly and reduces surface damage on softer materials like concrete blocks.

Are these anchors suitable for seismic zones? Yes, when properly installed according to manufacturer guidelines, many of our anchor types—including the flange nut sleeve and shark fin designs—are rated for use in areas with moderate seismic activity.
