NJMKT Torque‑Controlled Adhesive Anchor is a high‑performance ETA & CE certified bonded anchoring system, serving as a perfect cost‑effective replacement for Hilti and Fischer adhesive anchors. It features precise torque locking, zero expansion stress, full cracked concrete applicability, and long‑term anti‑fatigue stability, fully complying with Eurocode EN 1992‑4 for permanent structural anchorage in critical infrastructure.

Different from traditional expansion anchors that cause concrete extrusion damage and hidden loosening risks, this torque‑controlled adhesive anchor adopts dual mechanical locking and chemical bonding structure. Standard torque installation ensures consistent, inspectable construction quality on site. It eliminates over‑torque damage, supports small edge spacing installation, and maintains stable bearing capacity under seismic loads and long‑term dynamic vibration.

Certified for both cracked and uncracked concrete (C20/25–C50/60), the anchor provides 50‑year and 100‑year design service life options. It performs reliably in wet holes, high‑chloride coastal environments, low‑temperature construction (-5°C), and overhead vertical installation, ideal for steel structure fixing, mechanical base anchorage, curtain wall installation, rail transit and airport hub engineering.

Core Engineering Advantages

1. Precise Torque Control Installation

Uniform tightening torque standardizes installation quality, avoiding artificial construction errors. No design modification is required when replacing imported anchor brands.

2. Zero Expansion Stress

No concrete squeezing damage, allowing denser anchor layout and smaller edge distance, greatly improving structural installation flexibility.

3. Cracked Concrete Approved

Dual locking mechanism guarantees stable tensile and shear strength even when concrete cracks under load, meeting European high‑standard structural safety requirements.

4. Excellent Anti‑Fatigue & Seismic Performance

Certified for C2 seismic resistance and long‑term dynamic load stability, suitable for long‑term vibration scenarios of airports and rail transit projects.

5. Strong Environmental Adaptability

Stable performance in humid underground spaces, coastal corrosion environments and winter low‑temperature construction conditions.
