Rail Screw Dowel

Sdu Plastic Dowel
Rail screw dowel, also known as rail plastic sleeve, concrete sleeper insert, is a counter-party fastener for a sleeper screw or anchor bolt. It is pre-imbedded into the concrete or wooden sleeper tie. Jointed with screw spikes, guide plates and rail clips, the plastic screw dowel can fasten the steel rail.

Pre-inserted railway dowel is a kind of embedded plastic railway fastener. It is mainly installed and fixed in pre-made products (such as concrete sleepers, bridges, buildings, etc.). After the dowels are being tied with the pre-made products, it is then ulitized by bolts or screws for fixing and fastening with other objects.
Railway dowel material: nylon fiberglass (PA66+GF), plastic (HDPE), cast iron, etc.
