Railway Sleeper Twist Spike Spirial Screws
Other Name:Twist Spike ,Spirial Screws, Track Spike, Sleeper Screw
Railway 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.
ZY 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.
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.

5. Coach screw is used for the mining industry in South Africa
6. DHS35 rail sleeper screw spike, supports the use of the SKL14 rail
fastening system
7. Rail sleeper screw spike with round thread, according to the
standard NF-F 50014
8. Rail sleeper screw spike with two ends, fixes the rail together
with the Nabla clip system. This spike is very popular in Africa.
We use special material TD16 to produce the sleeper screw to meet
with the bending test, bending 30 degree and straightening it,
without crack.
9. Timber drive spikes can reduce installation and maintenance costs.
The spikes are used for timber construction highway crossing planks
and panels, bridge and trestle guard rails, motor car set-off,
docks, etc. The washer head is single forged and the excellent
holding power of threads provides tight installation. The spikes
are easily installed, driven with a maul or pneumatic spike driver.
They cannot be overdriven and are easily removed for reuse with a
hand or power tool. The drive spikes are available for a wide
variety of installations and maintenance of way, and meet with the
standard ASTMA66-87, cold bending 90 degree without crack.
