High Tensile Grade 4.6 Railway Sleeper Twist Spike Spirial Screws HDG Q235

 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.
 

Material

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.

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.
