Xinda Rail is a leading railway fastener supplier, providing raw materials for railway construction and daily maintenance work.
Rail bolts and nuts are commonly used components in rail fastening systems. Anchor bolts are used to fasten sleeper plates and sleepers, and T-bolts and nuts are mainly used to fasten rail clips (or rail blades, rail clamps) to help fasten rail tracks.
Xinda Rail produces world-class bolts and nuts for railways. These bolts are manufactured in accordance with European and American standards. The surfaces are ordinary galvanized, black galvanized and hot-dip galvanized. We can also provide bolts with special coatings such as HDG, PTFE, Geomet and Dacromet coatings.
High-strength bolts are a typical rail fastener made of high-strength steel. Like other types of rail bolts, high-strength bolts are used to connect the two ends of the track together.
The function of high-strength bolts is to prevent the movement of the track and ensure safety. In terms of type, most railway bolts are high-strength bolts, such as diamond-neck rail bolts, NF F50-008 rail bolts, fish bolts, HS26 and HS32 clamping bolts, special bolts, etc.
