Galvanized Rail T Bolt With Nut And Washer , Anti Rust Railway T Head Bolt Assembly

Galvanized T-bolt with nut and washer is a complete integrated fastening assembly consisting of a T-head bolt, heavy-duty hex nut, flat washer and spring washer. Also known as railway T-bolt, it is a dedicated fastener designed for rail clamping devices, steel rail fixing, tunnel support systems and industrial steel structure connections.

Manufactured from high-quality carbon steel and alloy steel with professional hot forging and heat treatment, our galvanized T-bolt assemblies deliver excellent tensile strength, shear resistance and anti-loosening performance. The whole set adopts premium galvanized surface treatment, forming a uniform zinc coating to provide long-term anti-rust and anti-corrosion protection for outdoor and humid working environments.

Supplied as a full matched set for one-stop installation, no need for separate accessory procurement. Standard sizes in stock and custom specifications are available. Widely used in railway track fastening, construction steel fixing, machinery equipment assembly and heavy-duty engineering projects for global railway contractors and bulk buyers.

• Complete Full Set Assembly Supplied as a finished set including T-bolt, hex nut, flat washer and spring washer. Perfect size matching, unified tolerance, no assembly mismatch, greatly improving on-site installation efficiency.
• Unique T-Head Structural Design Special T-shaped head structure effectively prevents bolt rotation and slipping during tightening. Fits perfectly with rail clamp grooves and fixed fixtures, providing ultra-stable clamping force.
• Premium Galvanized Anti-Corrosion Finish Integral galvanized treatment with uniform and adhesive zinc layer. Excellent resistance to rust, oxidation, salt spray and humid weather, greatly extending service life in outdoor railway engineering.
• High Mechanical Strength & Stability Made of high-grade carbon steel and alloy steel with quenching and tempering heat treatment. High tensile strength and shear resistance, not easy to deform or break under heavy load and long-term vibration.
• Dual Anti-Loosening Performance Equipped with matched spring washer for elastic anti-loosening and flat washer for uniform pressure dispersion. Effectively avoid loosening caused by train vibration and mechanical operation.
• Precision Thread Machining Standard precise thread with smooth engagement and tight fitting. Ensures firm locking, uniform stress and stable long-term fastening performance.

• Professional Railway Fastener Factory Specialized in manufacturing T-bolt assemblies for railway and industrial engineering for years. Strictly compliant with industry standards, stable quality and reliable performance.
• Strict Full-Range Quality Inspection 100% inspection on material hardness, tensile strength, thread accuracy, zinc layer thickness and matching degree of the whole set. Support SGS and third-party inspection.
• Complete Size Specifications Full range of standard M16, M18, M20, M22, M24 T-bolt sets in stock. Custom length, diameter and galvanized layer thickness are acceptable.
