Uls7 washer is a specific type of flat washer designed to be used with the Ss36 screw.
The Ss36 screw spike is used in various railway fastening systems, most commonly with concrete sleepers where it works in conjunction with plastic dowels. It can also be used with wooden sleepers to fasten the sole plate or ribbed base plate to the sleeper. These systems often include components like the SKL clip, and the Ss36 is a type of threaded screw spike used for both direct and indirect fastening.
These fasteners provide a strong, stable connection, particularly in concrete sleepers, by holding the tie plate or rail in place.
Concrete sleepers: The Ss36 screw spike is frequently used with concrete sleepers. It is screwed into a plastic dowel that has been pre-inserted into the concrete sleeper to create a secure anchor point for the rail clip and base plate.
Wooden sleepers: It can also be used in timber (wooden) sleepers, where it is directly screwed into the wood to hold the base plate and rail in place.
Part of a system: The Ss36 is not a standalone fastener. It is a component within a larger fastening system, such as the SKL clip fastening system, which also includes items like the SKL tension clamp, flat washer, guide plate, and rail pad.
Advantages:
Compared to older types of fasteners like dog spikes, screw spikes like the Ss36 have significantly greater holding power.
Material and finishes: The screws are typically made from carbon steel and can come in various finishes for corrosion protection, such as plain, Dacromet, oxide black, and hot-dip galvanized.
In summary, the "sleeper screw Ss36 with uls7 washer" is a specific, heavy-duty component of a railway fastening system, engineered to provide a strong and stable connection between rails and concrete sleepers.
