Rail joint bolts with nuts in size M27×160 are heavy-duty railway fastening elements used to securely connect rail joints and splice bars under high dynamic loads.They are also referred to as a fishbolt, track joint bar bolt, or splice bar bolt).
Specifications and Standards
· Thread Diameter: M27
· Length: 160 mm
· Standards: Manufactured to standards GOST 11530-76 for the track bolts and GOST 11532-93 / GOST-equivalent specifications for matching M27 track nuts.
· Material & Strength: High-strength structural carbon or alloy steel, available in strength classes 8.8 or 10.9.
· Coating: Protective zinc or phosphate coating for corrosion resistance in open-track or industrial environments.
· Application: Designed to be paired with appropriate spring/lock washers (such as ShS-27) to resist vibration and loosening under train traffic.
⚙️ Assembly Components
These fasteners are distributed in three distinct packaging forms:
1. The Bolt Alone: Just the M27×160 specialized track bolt.
2. Bolt with Nut: Complemented by an M27 track nut manufactured according to GOST 11532-76 (DSTU GOST 11532-93), featuring structural carbon steel and a protective zinc or phosphate anti-corrosion coating.
3. Complete Assembly: A package that includes the track bolt, the matching M27 nut, and a heavy-duty single-ring spring washer (such as the ShS-27 or AREMA type) to maintain tension and absorb track vibrations.

M27×160 rail joint bolts with nuts are heavy-duty railway fastening elements designed to securely connect rail joints and splice bars under high dynamic loads. Also commonly referred to as fishbolts, track joint bar bolts, or splice bar bolts, these high-strength fasteners play a critical role in maintaining track alignment and structural integrity under heavy train traffic.
Technical Specifications and Standards
· Thread Diameter: M27 (27 mm metric thread)
· Length: 160 mm
· Manufacturing Standards: Produced according to rigorous industry standards, including GOST 11530-76 for track bolts and GOST 11532-93 (or regional equivalent specifications) for matching M27 track nuts.
· Material & Strength Grade: Forged from high-strength structural carbon steel or alloy steel, available in premium strength classes 8.8 and 10.9 to resist severe shear stresses.
· Anti-Corrosion Coating: Finished with a protective zinc-plated or phosphate coating to prevent rust and corrosion in harsh open-track and industrial environments.
· Application: Engineered to be paired with heavy-duty spring/lock washers (such as ShS-27) to absorb constant vibrations and prevent loosening.
Heavy-Duty Assembly Components
To suit different maintenance and installation workflows, these specialized railway fasteners are typically distributed in three packaging configurations:
· The Track Bolt Alone: The standalone M27×160 specialized fishbolt featuring a standard oval or square neck to prevent rotation during tightening.
· Bolt with Matching Nut: The M27×160 bolt paired with a structural carbon steel M27 track nut manufactured according to GOST 11532-76 / DSTU GOST 11532-93 specifications.
· Complete Joint Fastener Assembly: A comprehensive kit containing the track bolt, matching M27 nut, and a heavy-duty single-ring spring washer (such as the ShS-27 or AREMA type) to maintain optimal clamping force.
