Screws
Description
ZHONGYUE is engaged in manufacturing and supplying a wide range of rail
sleeper screw. Designed with high precision and processed under
advanced technologies, these rail sleeper screws are manufactured
using high grade raw materials, satisfying all the quality
standards. With reliability, robustness and effective performance,
these products can be used in railway engineering.
Rail sleeper screw spikes are used to fasten sole plates and ribbed
base plates to wooden sleepers. In rail construction with the
concrete sleepers, the rail sleeper screw is used in combination
with a plastic dowel pressed in the concrete sleeper, indirect or
direct fastenings of rails on concrete and wooden sleepers.
Characteristically, the sleeper screw thread may only be produced
in a hotforming operation. The different shapes of the head
correspond to the pass form of the respective spanner used for
fastening and loosening of the rail sleeper screws.
The screw spike costs more to manufacture than the dog spike or dog
nail, but has the advantage of greater fixing power; approximately
twice that of a dog spike, and can be used in combination with
spring washers.
ZHONGYUE can supply a range of rail sleeper screw spikes manufactured to
international standards according to BS, ASTM and DIN, among
others. ZHONGYUE has extensive experience in the rail industry and a high level of
expertise in this specialized field. ZHONGYUE can manufacture any quantity, big or small, and offers a range of
finishes including hot dipped galvanized, black, sherardized or
self color for the budget conscious.
Rail sleeper screw spikes with big disk are mostly used in South
America and Africa
