Submit a request

Bolt M24×140 — a threaded fastener used in railway rail and turnout fastening systems. It is applied for the installation of joint fishplates, base plates, and clamps, ensuring a strong and durable connection of rail elements under dynamic and vibration loads. Widely used in major overhauls and routine maintenance of railway tracks.

Description and Design

Hexagon bolts M24×140 are manufactured in accordance with DSTU GOST R 52644-2006 (GOST 7798-70) from carbon or alloy steel with subsequent heat treatment. The bolt design includes a hexagonal head and a metric thread with a 3 mm pitch. The threaded portion may be partial or full. The surface is protected against corrosion by zinc plating, phosphating, or oxidation, allowing the bolts to be used in open-air railway operating conditions.

The bolt material provides high tensile and shear strength;
Geometry complies with ISO and GOST requirements for manufacturing accuracy;
Working load — up to 200 kN for strength class 10.9;
The coating ensures resistance to corrosion and wear;
Service life — more than 20 years under standard track operating conditions.

Application

Bolt M24×140 is used in KB, KBL, and KP rail fastening systems, as well as for connecting joint fishplates and turnout assemblies. It is applied in the construction and maintenance of railway lines, stations, industrial tracks, and sidings. Compatible with M24 nuts and standard spring or double-coil washers.

Advantages of M24×140 bolts:

High reliability of the connection under dynamic and vibration loads;
Long service life and corrosion-resistant coating;
Compatibility with all standard railway fastening components;
Easy installation and dismantling without thread deformation;
Compliance with Ukrzaliznytsia requirements and international ISO 4014 standards.

Supply and комплектation

We supply M24×140 bolts in batches of 100 pcs or more;
