High Tensile Tirafondos Tipo A0 23x105mm Railway Sleeper Screw
Other Name:Screw Spike ,Railway Spike, Railway Screw, Railway Nail
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.
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.
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

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.
