Hex bolt M24x90 - Specifications

Standard: DSTU GOST 7798-70

Product type: Hex head bolt M24×90

Material: Carbon or alloy steel (35, 40Kh, 09G2S), heat-treated; coating — zinc, phosphate, or oxide

Technical specifications:

Purpose: fastening rail baseplates, fishplates, and fastening elements in the upper structure of railway track
Thread diameter: M24
Bolt length: 90 mm
Thread pitch: 3 mm
Strength class: 8.8 / 10.9
Head type: hex head for 36 mm wrench
Thread type: partial or full (depending on design)

Submit a request

Bolt M24×90 is a threaded fastener used in rail fastening systems, joint connections, and installation assemblies of the upper railway track structure. It is used to secure baseplates, clips, and fishplates to sleepers, ensuring the strength and stability of the railway track under vibration and dynamic loads. It is applied on railway lines of all categories — mainline, station, and industrial.

Description and design

Hex head bolts M24×90 are manufactured in accordance with DSTU GOST 7798-70 from structural steel with heat treatment to achieve the required level of strength and elasticity. The product design includes a hexagonal head for a 36 mm wrench and a metric thread with a 3 mm pitch. Bolts are supplied with partial or full thread depending on the type of connection. The surface is protected with zinc or phosphate coating to ensure corrosion resistance in open-track conditions.

High precision of thread execution and head geometry;
Increased resistance to tensile and torsional loads;
Working load — up to 180–200 kN for strength class 10.9;
Anti-corrosion coating ensures long service life;
Service life — at least 20 years under standard track loads.

Application

Bolt M24×90 is used in railway rail fastening systems of types KB, KBL, KP, as well as in connections of fishplates, baseplates, and clips. It is applied during major and routine track maintenance, on turnouts, and on industrial sidings. Compatible with M24 nuts and washers in accordance with GOST 6402 (spring, double-coil, and flat).

Advantages of M24×90 bolts:

High reliability and strength of the connection;
Retention of tightening force under vibration and temperature fluctuations;
Ease of installation and dismantling without loss of thread geometry;
Resistance to corrosion and mechanical wear;
Compliance with Ukrzaliznytsia technical requirements and ISO 4014 standards.

Supply and комплектation

Bolt M24×90 supplied in batches of 100 pcs or more;
Each batch undergoes strength, thread, and coating quality inspection;
Nuts and washers supplied upon customer request;
Delivery across Ukraine by road and rail transport from the warehouses of «Prombudkoliya».
