Fasteners, Seals & Hardware

Essential Components for Every Heavy Machinery Assembly

Fasteners, seals, and hardware are the backbone of every heavy-duty machine. From massive excavators and wheel loaders to industrial compressors and piling rigs, each system relies on secure fastening, tight sealing, and durable hardware to maintain operational integrity. At 3GEN Export, we supply a complete range of OEM-grade fasteners, seals, and precision hardware designed for the world’s toughest working environments.

These components may seem small, but their function is critical. A single bolt, O-ring, or locking plate can determine whether a machine performs flawlessly or fails under pressure. That’s why we ensure every fastener and seal we supply meets international OEM specifications and passes rigorous quality control tests for strength, vibration resistance, and temperature endurance.

Comprehensive Range of Fasteners

Bolts, Nuts, Washers & Studs

Our fasteners are engineered for maximum tensile strength, corrosion resistance, and precision threading. Manufactured from high-grade steel alloys and treated with zinc or phosphate coatings, they ensure lasting reliability in high-load and high-vibration environments.

• Bolts – Available in hex, flange, socket, and carriage types, all precision-machined to meet ISO and DIN standards.
• Nuts – Lock nuts, flange nuts, and castle nuts provide secure fitment for all heavy-equipment assemblies.
• Washers – Flat, spring, and sealing washers that distribute load evenly and prevent surface wear.
• Studs – Used for flange and housing applications, providing durable anchoring in engines, hydraulic systems, and structural joints.

Each fastener undergoes tensile, hardness, and torque testing to guarantee consistent performance under extreme vibration, impact, and temperature variations. Whether assembling a hydraulic valve or securing a transmission housing, 3GEN Export’s fasteners deliver long-term stability.

Advanced Sealing Solutions

O-Rings, Seals & Gaskets

In hydraulic, pneumatic, and fuel systems, preventing leakage is vital. 3GEN Export’s sealing components are manufactured from premium-grade rubber and polymer materials—such as NBR, FKM (Viton), EPDM, and PTFE—to withstand high pressure, oil exposure, and temperature extremes.

• O-Rings – Available in metric and imperial sizes for universal compatibility across pumps, valves, and cylinders.
• Seals – Shaft seals, lip seals, and mechanical seals that protect bearings and moving parts from contamination.
• Gaskets – Precision-cut metallic and non-metallic gaskets for perfect sealing between flanges, casings, and manifolds.

Our seals and gaskets are widely used in construction, mining, and industrial applications where reliability under pressure is non-negotiable. Every product is designed for a perfect OEM fit, ensuring easy installation and long service intervals.

Precision Hardware for Structural Integrity

Retaining Rings & Locking Plates

Retaining and locking components are small but crucial elements in machine safety and stability. They hold shafts, gears, and bearings in precise alignment, preventing mechanical dislocation and unwanted vibration.

• Retaining Rings – Internal and external types for shafts and bores, ensuring tight axial retention.
• Locking Plates – Used to secure critical connections and prevent loosening under torque stress.
• Snap Rings & Cotter Pins – Provide quick and secure assembly solutions for field maintenance.

At 3GEN Export, all hardware is produced with strict dimensional accuracy, surface hardness, and corrosion-resistant finishes, guaranteeing mechanical reliability even under heavy shock loads.

Applications Across All Heavy Machinery

Our Fasteners, Seals & Hardware category serves every machinery group in the 3GEN Export ecosystem:

• Excavators, wheel loaders, bulldozers, and graders
• Drilling and piling rigs (BAUER, LIEBHERR, SOILMEC, SANY, XCMG)
• Crushers, compressors, and hydraulic systems
• Agricultural, forestry, and marine machinery

Whether you’re maintaining a single hydraulic pump or rebuilding an entire undercarriage, these parts ensure that each component functions as designed. They provide the unseen strength behind every bolt torque, the leak-free seal that keeps fluids contained, and the locking plate that keeps assemblies stable in the harshest sites.
