Submit a request

Claw bolts are specialized fastening components used in turnouts and rail assemblies to secure stock rails, guard rails, as well as shoes and plates. The bolt design ensures reliable fixation due to the claw-type head, which prevents rotation during installation. They are used on mainline, station, and industrial railway tracks.

Description and design

Claw bolts are manufactured in accordance with TU 32-TsP-395-84 from alloy structural steel with heat treatment. A distinctive feature of the design is the flat claw-type head with lateral lugs, which is fixed in the slot of a rail element or metal component. This ensures bolt stability during nut tightening and eliminates the need to hold the head with a tool. The bolt is supplied with a nut and a washer (spring or double-coil).

High strength and reliability when tightening heavy turnout components;
The claw-shaped head prevents rotation during installation;
Quenching and tempering provide resistance to fatigue loads;
The coating protects against corrosion during outdoor operation;
Service life — not less than 25 years under standard track operating conditions.

Application

Claw bolts are used during assembly and installation of turnouts (SPR-50, SPR-65), as well as for fastening guard rails and shoes to stock rails. They are applied on turnout sections, curves, bridges, and industrial tracks. The bolts provide a strong and stable connection of components that are subjected to transverse and longitudinal loads from rolling stock.

Advantages of claw bolts:

Reliable fastening without head rotation during tightening;
Strength and durability under repeated dynamic impacts;
Compatibility with all types of turnouts and rail systems;
Resistance to corrosion, temperature fluctuations, and vibrations;
Compliance with Ukrzaliznytsia requirements and TU 32-TsP-395-84 standards.

Supply and delivery

Claw bolts supplied in sizes M24×180, M24×220, M27×200, M27×240, and others;
Each batch undergoes inspection of geometry, thread quality, and metal hardness;
Supplied with M24–M27 nuts and ShS-27 washers upon customer request;
Delivery across Ukraine by road and rail transport from the warehouses of «Prombudkoliya».
