Oval Neck Bolts

Frequently referred to as fishtail bolts, egg neck bolts, or track bolts, oval neck bolts feature a unique design. With a round head and an oval neck, these bolts are also known as round head oval neck bolts or egg bolts. The thread on these bolts varies in length, giving them their distinctive appearance and functionality.

The oval neck bolt, commonly coated with zinc or yellow zinc, is primarily used to connect track joint splints and grooved pipe fittings, providing a secure fixation. It pairs well with hex flange nuts or regular hex nuts, often accompanied by hex heavy nuts. For added durability, round head oval neck bolts can be coated with Dacromet or H.D.G. When installing a grooved pipe fitting, two sets of oval neck bolts and nuts are typically required. The most commonly used grade for oval neck bolts is grade 8.8, although grade 9.8 is also available. The flange nut used in conjunction with oval neck bolts can be serrated or non-serrated.

Railway tracks require sturdy bolts for their connection, and the track bolts used are usually of a similar type. These bolts are made from materials such as Q235 and 45# steel and come in two types: metric oval neck bolts and AMSE oval neck bolts. Both are commonly coated in either black oxide or H.D.G. In particular, these bolts are widely utilized in connecting rail joints and play a vital role in ensuring the stability and safety of the tracks.
