are also called railway sleeper screws, railroad tie nails, or rail screw spikes. It's a fastener, especially used to fasten the railroad. Just like dog spikes, they usually adopt high-strength carbon steel or stainless steel materials, and through heat treatment technology to add their strength and durability. However, due to the screw spikes' complicated process, they usually have a higher price than dog spikes.
The B0 type railway sleeper screw spike is a medium or large metal screw used to fasten steel rails to wooden or concrete sleepers. It typically features a square or rectangular head and a threaded rod with a single, high-pitch thread to provide strong holding power.

Installing the Ss35 screw spike requires adherence to specific procedures to ensure optimal performance and safety. Here are the general steps involved:
- Prepare the rail sleeper or concrete tie by drilling a precise hole according to the spike's specifications.
- Insert the Ss35 screw spike into the hole, ensuring it is securely positioned.
- Utilize appropriate tools, such as a wrench or spike maul, to tighten the screw spike until it is firmly fixed in place.
- Repeat the process for the remaining spikes, maintaining consistent spacing and alignment along the rail.
