Product Description

Fishtail bolt is a special type of threaded fastener, named after its unique head shape, usually resembling a fish tail. It plays an important role in track laying and other fields.
characteristic:
-A concave arc surface is formed between the bolt head and the screw to enhance the tensile strength bearing capacity.
 
-The head has a unique shape, usually resembling a fish tail.
 
-The tail is conical, resembling a fish tail shape.
 
-The diameter is usually larger than the length, making it easier to fix the parts.
Purpose:
 
-Mainly used for the connection of track joint clamps (fishplates), playing a fixing role.
 
-Widely used for track laying in industries such as metallurgy, coking, and steel.
 
-Fishplates are used to fix the joints of steel rails, ensuring the stability and safety of the rails.
 
-It can also be used for fixing groove fittings.
 
Model and Material:
 
-There are various models, such as M14 * 70, M16 * 80, M18 * 80, etc.
 
-The materials include Q235, 45 # steel, high-strength alloy steel, carbon steel, stainless steel, aluminum alloy, etc.
 
Installation precautions:
 
Use appropriate tools to ensure moderate tightening torque.
 
Clean the connection parts before installation to remove oil stains and dust.
 
Pay attention to the left and right rotation directions of the thread to ensure correct installation.
 
In track laying, the contact parts between the fishplate and the steel rail, as well as the bolts, need to be coated with oil.
 
When threading fishtail bolts, the nuts must be staggered inside and outside.
 
Procedure for tightening bolts: First, use a four hole fishplate to tighten the two middle ones, then tighten the two sides. After tightening both sides, tighten the two middle ones again.
