R54/R42 Railway coach screws with washer

R54/R42 railway coach screws with washers are self-tapping sleeper screws used to fasten rail chairs or baseplates to timber sleepers. They're a type of rail spike in a railway fastening system, similar to coach bolts but with a tapered tip for self-tapping. 

Unlike bolts, coach screws have a tapered tip, allowing them to create their own threads when driven into the wood. R54 and R42 refer to specific thread sizes and lengths, likely in metric units (e.g., R54 might be R = 54 mm, and R42 = 42 mm).
