Zinc Plated Oval Neck Bolt

Railway tracks often require the use of high-strength fishtail bolts. These bolts are designed to withstand the pressures and stresses associated with train traffic. To enhance their performance and longevity in outdoor environments, various surface treatments such as black oxide and hot-dip galvanizing are typically employed. These treatments not only improve the anti-corrosion ability of the bolts but also significantly extend their service life. When it comes to fishtail bolts, larger sizes like M24 track bolts are commonly used. With their enhanced durability and stability, these bolts contribute to the overall reliability and safety of railway tracks.

The connection of grooved pipe fittings typically involves the use of ordinary fishtail bolts. These bolts are commonly treated with electro-galvanizing or zinc plating for surface protection. Oval neck bolts in sizes such as M10, M12, and M16 are often the preferred choice for this application.

To enhance the anti-rust ability of track bolts, a coating is applied. The coating is designed to meet specific requirements regarding the salt spray time. For example, an oval neck bolt must not show any red rust in 24 hours. However, if you require a longer time, it is possible to provide coatings that offer 72 hours or 120 hours or more without any red rust. Of course, the more extended the time, the higher the price. Therefore, it is advisable to select the appropriate coating for your oval neck bolts.

The usage of oval neck bolts is quite limited, as they are mainly utilized in connecting track joint splints (aka fishplates) and grooved pipe fittings to provide a steady and secure function.
