Fumigation free Pallet. Clients can appoint the way. A screw spike, rail screw (or lag bolt) is a large (6 in or 152 mm length, slightly under 1 in or 25 mm) metal screw used to fix a tie plate or fasten rail. Screw spikes are fixed into a hole bored in the sleeper. The screw spike has a higher cost to manufacture than the rail spike but has the advantage of greater fixing power; approximately twice that of a rail spike, and can be used in combination with spring washers. We are a leading Railway Screw Spike manufacturer in China. We can also make other rail fastenings such as railway screw, plastic dowel, rail pad, railway insulator, rail fish bolt, railway base plate, rail anchor, railway shoulder, rail bolt, flat and spring washer, fastening system of E type/SKL type/KP type/Nabla type.

There are M.C.I. shoulder manufactured from malleable iron and S.G.C.I. shoulder manufactured from malleable iron and S.G.C.I. shoulder from spheroid graphite iron. We offer two types of iron shoulders. One is Single Stem Iron Shoulder used in pre-stressed concrete ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block concrete ties. We can also provide Weld-on shoulder is used for the typical position of rail. This rail cast iron shoulder is welded on flat steel plate instead of the standard tie plate and is produced according to AREA standard. Designed for use with E style elastic rail clips, the weld on shoulder fastening allows customers to fabricate rail retaining units on both steel sleepers and steel base plates. We are a leading rail shoulder manufacturer in China. We can also make other rail fastenings such as railway screw, plastic dowel, rail pad, railway insulator, rail fish bolt, railway base plate, rail anchor, railway shoulder, rail bolt, flat and spring washer, fastening system of E type/SKL type/KP type/Nabla type

The tie plate increases bearing area and holds the rail to correct gauge. They are fastened to wooden ties by means of spikes or bolts through holes in the plate. The part of the plate under the rail base is tapered, setting the cant of the rail, an inward rotation from the vertical. The usual slope is one in forty ( 1.4 degrees ). The top surface of the plate has one or two shoulders that fit against the edges of the base of the rail. The double-shoulder type is currently used. Older single-shoulder types were adaptable for various rail widths, with the single shoulder positioned on the outside (field side) of the rails. Most plates are slightly wider on the field side, without which the plates tend to cut more into the outsides of the tie, reducing cant angle. Cast iron can be the welded or fabricated type, depending upon the customers requirements. Our rail tie plate can be made to suit various rail section, i.e. UIC 60, UIC 54, RN 45, 90 A, etc. We are a leading rail tie plate manufacturer in China. We can also make other rail fastenings such as railway screw, plastic dowel, rail pad, railway insulator, rail fish bolt, railway base plate, rail anchor, railway shoulder, rail bolt, flat and spring washer, fastening system of E type/SKL type/KP type/Nabla type.

Railway Insulator PA66: Nylon 66.69%, Glass Fiber 30%, Other 1% Railway Insulator is used in the E fastening, SKL fastening and Nabla Fastening system in the railway.
