Cast In Channel T Bolts are specially designed fasteners for use with cast-in channels, providing secure, adjustable, and reliable connections. HULK Metal manufactures them with advanced forging and machining technology, ensuring accurate dimensions and excellent surface finishes. With robust material selection, surface treatments, and strict quality inspections, our T Bolts deliver higher strength, corrosion resistance, and durability, making them a trusted solution for precast concrete and structural anchoring applications worldwide.
Cast In Channel T Bolts are engineered fasteners designed to work exclusively with cast-in channels. They feature a unique parallelogram-shaped head, which allows easy insertion into the channel. Once rotated, the head locks firmly against the channel's edges, creating a stable connection. A groove near the threaded section of the head ensures secure engagement when tightened, preventing loosening during service.
These bolts are typically manufactured using high-performance alloy steel or stainless steel, offering superior strength and resistance to mechanical stress. To protect against rust, alloy steel bolts are treated with electro-galvanizing or hot-dip galvanizing, while stainless steel options offer natural corrosion resistance.
Due to their load-bearing reliability, Cast In Channel T Bolts are widely used in precast concrete construction, curtain wall installations, and structural fixing applications. Their combination of strength, durability, and adjustability makes them indispensable for modern construction projects.

Cast In Channel T Bolts are designed to fit securely into cast-in channels. Their unique head design ensures strong engagement, providing high load capacity and reliable fixing for structural assemblies in construction, infrastructure, and precast concrete applications.
T-Bolts feature a T-shaped head that locks firmly into channel slots when rotated. They are commonly used in modular fastening systems, offering excellent stability, quick installation, and adjustability for various industrial and construction connections.
When inserted into a cast-in channel, the T Bolt's head aligns with the channel opening. After rotation, the parallelogram-shaped head locks against the channel edges. When tightened, the groove ensures secure engagement, distributing loads evenly for a stable and long-lasting connection.
We carefully analyze your order requirements, including bolt specifications, quantities, surface treatments, and delivery schedules. Our technical experts then prepare a complete production plan to ensure every Cast In Channel T Bolt matches your project's needs.
