Engineered for modern construction where precision, speed, and safety are paramount, our Twist-Off High-Strength Bolts (also known as Tension Control Bolts or TC Bolts) offer a foolproof solution for critical steel structure connections. Unlike traditional fasteners that require complex torque calculations and specialized wrenches, these bolts feature a unique shear-torque mechanism. The calibrated spline end shears off cleanly once the target preload is achieved, guaranteeing consistent tension and eliminating human error.
Key Features & Benefits
- Automatic Preload Verification: No torque wrench needed. The bolt head automatically breaks off at the correct tension, ensuring every connection meets strict engineering standards without guesswork.
- Enhanced Construction Efficiency: Reduce installation time by up to 40%. The simple "tighten until break" process requires minimal training, accelerating project timelines for skyscrapers, bridges, and industrial plants.
- Superior Material Quality: Manufactured from high-grade alloy steel and subjected to rigorous quenching and tempering processes. Available in Grade 10.9S and Grade 8.8, delivering unmatched tensile strength, fatigue resistance, and durability under heavy loads.
- Corrosion Resistance: Designed for harsh environments. Surface treatment options include Hot-Dip Galvanized, Zinc-Plated, and Dacromet coatings, ensuring long-term structural integrity and protection against rust and weathering.
- Compliance & Safety: Fully compliant with GB/T 3632 standards and aligned with international ISO 898-1 requirements. Each batch undergoes strict quality control and mechanical testing to ensure traceability and reliability.
- Applications
- Our twist-off bolts are the preferred choice for engineers and contractors in:
- High-Rise Buildings & Skyscrapers: Ensuring secure frame connections.
- Bridge Engineering: Withstanding dynamic loads and vibration.
- Industrial Plants & Warehouses: Fast assembly of large-span steel structures.
- Transmission Towers & Infrastructure: Reliable performance in extreme weather conditions.
