Railway Spike 16x16x165

The 16x16x165mm railway spike (also known as a dog spike, track spike, or cut spike) is a heavy-duty steel fastener designed for mainline railway networks, heavy industrial lines, and busy transit turnouts. The dimensions specify its structural footprint: a robust 16mm x 16mm square shank cross-section paired with a 165mm total length. Driven through steel baseplates into wooden sleepers, its primary job is to secure the rail foot, counteract powerful longitudinal and transverse track displacement, and maintain precise rail gauge alignment under intense dynamic train loads.

Key Features & Technical Specifications

· Heavy-Duty Dog Head: Features an asymmetric L-shaped head with side lugs that grip the bottom flange of the steel rail flushly.

· Chisel Wedge Point: The flat, wedge-shaped tip slices cleanly across wood fibers when driven parallel to the track, maximizing timber compression while preventing the wooden sleeper from splitting.

· Maximum Holding Strength: The 16x16mm square geometry delivers 50% more holding friction against wood grain than a smooth, round fastener of equal mass.

· Track Compatibility: Manufactured to rigid standards like GOST 5812-82, making it perfectly compatible with tie plates for heavy R-50, R-65, and R-75 rail profiles.

· Material Properties: Typically forged from high-tensile structural carbon steel (such as Q235, 35#, or 45# carbon steel) with localized surface hardening to withstand extreme fatigue and shear forces.
