8.8 Grade 45# steel coach screws Spike with yellow zinc coating

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 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.

Note ( 8.8 as a sample)

the first 8: tensile strength of material 45# is 800MPa;

the second 0.8: the yield ratio is 0.8;

the yield strength of material 45# is 800MPa x 0.8 = 640 MPa.
