Railway Screw 24x150

The 24x150mm railway screw spike (also known as a sleeper screw, rail screw, or coach screw) is a premium, high-resistance fastener engineered for modern mainline rail networks, high-speed lines, and heavy-haul tracks. The dimensions specify its robust metric footprint: a 24mm nominal thread diameter paired with a 150mm total length. Unlike traditional cut spikes, screw spikes are threaded directly into plastic dowels embedded in concrete sleepers (ties) or pre-drilled wooden sleepers, providing unmatched anchoring power against intense vertical and lateral dynamic forces.

Key Features & Technical Specifications

· High-Torque Drive Head: Features a heavy-duty square or rectangular head designed to handle high mechanical torque during automated track installation.

· Deep-Thread Geometry: Engineered with specialized, coarse threads that maximize surface contact, yielding up to two to three times the pull-out resistance of a standard smooth dog spike.

· Track Compatibility: Commonly manufactured to international standards like UIC, DIN, BS, or GOST, making it perfectly compatible with high-speed UIC60, R-65, and heavy industrial rail profiles.

· Premium Materials: Forged from high-tensile carbon steel or alloy steel (such as Q235, 35#, or 45#), typically available in high-strength mechanical grades like 4.6, 5.6, or 8.8.

· Corrosion Protection: Finished with advanced surface treatments—including Hot-Dip Galvanizing (HDG), zinc plating, or black oxide—to resist harsh outdoor environments, moisture, and track vibrations.
