24x230mm Ss36 Sleeper Screw

The 24x230mm Ss36 sleeper screw is a critical component of the railway track fastening system, used to securely attach rails to sleepers, ensuring gauge accuracy and track structure stability. This threaded screw provides excellent pull-out resistance and holding strength, effectively countering longitudinal and lateral vibrations from train operations, reducing track loosening and wear, and ensuring long-term track safety.

Screw Spike Quality Inspection

 

First of all, screw testing should be implemented at the beginning of wire rod of the screw. The quality of precision screw is directly related to production of wire.

 

The second step is to inspect head screw forming. Mould testing is the most important for forming process of screw spike. Good mould is the premise that makes good screw spike. Then next step is to inspect production machine of screw spike, which is conducive to safe and smooth production. Formed screw spike should be inspected whether it is with any burrs or not and then be measured for its accurate size.

 

 

The third step is about detection of screw thread. The detection of thread pitch should also meet the requirements of customer and international standards.

 

The last step is the screw shipment inspection. The method is to pick out the screw spikes that are not qualified, and then leave the best quality screw spikes to the customer.
