EN 14399 Structural Bolt Set (HV System)

Description

Product Overview
EN 14399 Structural Bolt Set (HV System) is a precision-engineered high-strength bolting system manufactured to the EN 14399 standard for non-preloaded structural connections. It comprises calibrated high-tensile bolts, nuts, and washers specifically designed for Heavy Vehicle (HV) and high-load structural applications. The set provides predictable clamping, consistent joint performance, and reduced installation variability, delivering safer and more reliable steel-structure assemblies. Strategically, this product reduces project risk, simplifies quality assurance, and accelerates construction schedules for infrastructure, heavy engineering, and industrial fabrication projects.

Key Specifications & Technical Characteristics

• Standard: EN 14399 series compliance for structural bolting (HV system), manufactured and traceable to batch-level inspection records.

• Materials: High-strength alloy steel (e.g., medium-carbon alloyed steel quenched and tempered), chemically passivated or coated per buyer specification.

• Mechanical grade: Typically Class 8.8 to 10.9 equivalent performance per EN/ISO mechanical classification; final grade specified on order.

• Surface finish: Options include class-specific mechanical zinc flake coating, hot-dip galvanizing, or plain clean black with passivation; coating thickness and salt-spray resistance per purchaser requirement.

• Dimensions: Full range of diameters and lengths available to EN metric standards (diameters M12–M36 typical; bespoke sizes on request).

• Tolerances: Machined and heat-treated to EN dimensional and tolerance requirements to ensure fit and torque predictability.

• Washers & nuts: Hardened, calibrated washers and nuts matched to bolts; nuts rolled or forged to standard thread fit, with locking or prevailing-torque options available.

• Packaging: Industrial unit packaging in labeled cardboard boxes or crates, shrink-wrapped on wooden pallets; bulk options in steel-reinforced crates or bulk pallets with moisture barrier.

• Traceability: Batch numbering, mill certificates (EN 10204 3.1/3.2 on request), and hardness/tensile test certificates included.

• Shelf life: Indefinite for non-coated steel when stored dry; coated components maintain specified corrosion protection for 12–36 months depending on storage conditions and coating type.

• Secondary services: Torque/tension specifications, installation guidance, and R&D testing reports available upon request.

Core Industrial Applications

• Primary industries: Structural steel fabrication, bridge and civil infrastructure construction, petrochemical and power plant construction, heavy machinery and mining equipment assembly, offshore platforms, and modular building systems.

• Operational use cases: Non-preloaded high-strength connections where slip-critical performance is required under shear and tension loads; connections in lattice towers, girders, crane mounts, base plates, and structural joints subject to dynamic loading.

• Performance over alternatives: EN 14399 HV bolt sets deliver consistent clamping forces and predictable slip behavior compared with generic high-tensile bolts, reducing rework and inspection cycles. Engineered material and matched washer/nut combinations increase fatigue resistance and joint durability under cyclical loads.

• Commercial relevance: Faster installation through standardized components, lower lifetime maintenance costs due to matched and certified components, and reduced on-site testing requirements because of factory-controlled quality and supplied documentation.

Competitive Advantages

• Quality consistency: Manufactured under controlled heat-treatment and finishing processes with batch-level testing and full certification options to support auditable quality systems.

• Supply reliability: Industrial-scale production capacity, buffer inventory for bulk buyers, and planned lead times aligned with project procurement cycles.

• Logistics capability: Palletized, export-ready packing, options for container loading optimization, and partnerships with freight forwarders for on-time global delivery.

• Price competitiveness: Economies of scale for bulk orders (20 MT+), competitive unit pricing with transparent cost breakdowns for coatings and certifications.

• Sustainability: Options for low-VOC coatings and supplier compliance with environmental management systems (ISO 14001) available on request.

• Technical support: Detailed torque/tension charts, installation procedures, acceptance criteria per EN standards, and post-sale engineering support for fitment and joint design.

Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Loading capacity (MT per container): Typical container loading depends on container type and packaging:

  • 20′ GP container: approximately 18–20 MT (palletized, depending on dimensions).

  • 40′ GP container: approximately 25–28 MT.

  • 40′ HC container: approximately 26–30 MT.
