Stainless Steel Railway Track Fasteners , GOST ANSI Black M10 Bolts Finishing Surface

Fishtail bolt is a kind of fastener that is mostly used in the connection of track joint splints (fishplates) and plays a fixed role. Sometimes fishtail bolts can also be replaced by hexagon bolts. In addition to being used in turnouts, fishtail bolts can also be used in metallurgical industry and coking industry. Fishtail bolts are generally hot-pressed by friction presses, with a buckle length of 50mm, and are also formed by cold heading, which are mostly used in the connection of rail joints.

1. The contact parts between the fish plate and the rail and the bolts should be oiled.

2. When wearing fishtail bolts, the nuts must be staggered inside and out.

3. The procedure of tightening the bolts, such as using a four-hole fish plate, tighten the middle two first, then tighten the two sides, and after tightening the two sides, tighten the middle two again.

4. When screwing the fishtail bolts, one person should use a 55cm screw wrench. Do not use a too long screw wrench or two people.

5. When the fishtail bolt cannot be worn, use a hammer to hit both ends of the fishtail plate, align the eyes, and do not drive the fishtail bolt with a hammer.

The above are some of the problems that should be paid attention to when installing the fishtail bolts on the fishplate. I hope that the majority of users can use the fishtail bolts reasonably to achieve a good tightening effect. Of course, if you still have doubts about fishtail bolts, or want to buy a batch of fishtail bolts, you can contact our company directly.

Introduction of fishtail bolts

Fishtail bolts (fishtail wires) are mostly used in the connection of track joint splints (fishtail plates) for fixing, and sometimes hexagonal bolts can be used instead.

Fishtail bolts, also known as fishtail wires or rail bolts, are different in shape from hexagonal bolts, with a semicircular head at the root and two protrusions inside the round head. It is called fishtail wire or fishtail bolt because it is used for the connection and fastening of rail fishplate.

Bolts, mechanical parts, cylindrical threaded fasteners with nuts. Bolt: A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Models size are Φ14×70, Φ16×75, Φ18×90, Φ20×90, Φ22×135, Φ24×135, Φ24×145, Φ24×170, etc. Generally, it is hot-pressed by friction press, the buckle length is 50mm, and there are also cold Upsetting is mostly used in the connection of rail joints.
Materials are: Q235 and 45# steel and insulated fishtail bolts, etc.

Surface requirements of fishtail bolts:

According to different needs, the surface has white, galvanized, nickel-plated, chrome-plated, hot-dip galvanized, military green, color yellow, which is to anti rust function process.

Usage of fishtail bolts

Fishtail bolts are mainly used in track laying in the metallurgical industry, coking industry, and iron and steel industry, and the rail and rail joints are connected and fastened.

An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an ASME B18.2.1 hex capscrew to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.
