Railway turnouts face some risks such as points being incorrectly set, points moving or reversed, etc. which might cause a collision or derail even worse. Because turnouts have so many potential risks, they greatly influence the safe running of a railway. Large frog bolts with high strength are fixed on the railroad frog to reduce risks and increase the safety of railway running. This type of railroad fastener is especially welcomed by American and UK customers.
Frog bolt Made By AGICO
AGICO offers a square head and button head oval neck or elliptical neck frog bolt made from medium carbon or alloy steel. The frog bolt produced by AGICO has a self-locking nut that can be customized with nylon or metal materials. Grade 8 bolts with different lengths and diameters are manufactured to suit various rail section dimensions of the railway turnouts. We also can manufacture frog bolts with the required specifications according to customer drawings. The installation of a frog bolt can use torque wrenches to ensure proper torquing.
