Application Of Screw Spike in Nabla Rail Fastening System

Sep 03, 2025 Leave a message

The screw spike is also known as rail screw. As one kind of Rail spike, it is a metal screw for fixing rail fasteners. Screw spike is usually made of NO.3 steel. Because its nail rod surface has thread, so it is called screw spike. The pull-out resistance is 0.5 ~ 1.0 times larger than that of common rail spike, but the thrust resistance is 50% less.

 

GNEE RAIL can provide various standards and specifications of rail spikes, such as dog spikes, SS series sleeper screws, square head screw spikes, hexagon screw spikes, double-head screw spikes, etc., and offers customized services according to customer requirements.
