Railway sleeper fixing screws Black Oxide ISO 24 Dia 160 Length SS8

Product Specification

Railway sleeper fixing screws Black Oxide ISO 24 Dia 160 Length SS8
 
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.
 
 
 
Material
 

 
Note ( 5.6 as a sample)
the first 5: tensile strength of material 35# is 500MPa;
the second 0.6: the yield ratio is 0.6;
the yield strength of material 35# is 500MPa x 0.6 = 300 MPa.

7.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.
