Galvanized White Yellow Carbon Steel Tam Anchor

TAM Shield Anchor: High-Performance Expansion Bolt for Heavy-Duty Construction Applications

Engineered for superior anchoring performance in demanding environments, the TAM Shield Anchor is a robust and reliable fastening solution designed for concrete, dense natural stone, metal structures, and architectural cladding systems. This innovative anchor features a unique dual-fin design combined with a shield-shaped body that ensures exceptional grip and anti-rotation capabilities during installation. Its precision-engineered steel construction offers maximum load-bearing capacity while maintaining ease of use across diverse industrial and commercial projects worldwide.

Key characteristics include a fully formed steel body made from a single sheet, rolled into a butterfly-like shape and segmented into four shield sections connected via a high-precision punching process. The double fins provide enhanced friction within pre-drilled holes, significantly improving holding strength. A red plastic plug integrated into the cone Nut protects internal threads from debris and moisture, ensuring smooth operation and long-term durability—even under extreme conditions. These features collectively make the TAM Shield Anchor an ideal choice for applications requiring both mechanical reliability and aesthetic integrity.

Manufactured to meet international standards for structural integrity, this heavy-duty Expansion Anchor excels in environments where traditional anchors may fail due to vibration, thermal stress, or material degradation. Available in various sizes and configurations, it supports secure mounting of railings, beams, brackets, windows, and heavy equipment on masonry, reinforced concrete, and stone substrates. Installation is straightforward: drill a hole matching the anchor diameter, insert the anchor, and tighten the nut until full expansion occurs—no special tools required. The result? A seamless, vibration-resistant connection that stands up to years of service life.

Commonly referred to as a Tam Anchor, Shield Bolt, Shell Bolt, or Marble Fixing System, this product serves a wide range of industries including building façade engineering, bridge construction, mining infrastructure, and industrial machinery installation. It's especially popular in regions where seismic resilience, corrosion resistance, and high tensile strength are critical factors in structural safety.

Users consistently praise its consistent performance across different substrate types—from granite and marble to precast concrete and steel frameworks. Many contractors note how the anchor’s anti-rotation feature prevents loosening over time, even when subjected to dynamic loads or frequent maintenance access. Additionally, the protective thread cap reduces the need for post-installation cleaning or re-threading, saving labor costs and enhancing project timelines.

For those considering alternative anchoring methods, the TAM Shield Anchor provides a cost-effective upgrade over older-style wedge or Sleeve Anchors, offering better load distribution, reduced risk of pull-out failure, and improved compatibility with modern fastening techniques such as dry-wall anchoring and curtain wall systems. Whether used in new builds or retrofitting existing structures, it delivers peace of mind through proven engineering and field-tested reliability.

Frequently asked questions often center around optimal drilling depth, compatibility with hollow walls, and whether it can be reused after removal. While best suited for solid materials like concrete and stone, it should not be used in lightweight or porous substrates without proper evaluation. Reuse is generally discouraged due to potential thread wear and loss of expansion force. Always follow manufacturer guidelines for embedment depth and torque specifications to maximize safety and efficiency.
