ISO 4017 fully threaded bolt

Description

1. Product Overview

ISO 4017 fully threaded bolt is a precision-engineered hexagonal-head fastener manufactured to international ISO 4017 specifications for fully threaded bolts. It is used to create secure, adjustable connections in structural assemblies, heavy machinery, piping supports, and equipment anchoring across construction, oil & gas, mining, and heavy manufacturing. The key value proposition is consistent dimensional accuracy and high tensile performance that enable predictable clamping force, reduced rework, and longer in-service life. Strategically, this product reduces procurement risk for large-scale industrial projects by standardizing on an internationally recognized fastener specification that simplifies inventory, inspection, and compliance.

2. Key Specifications & Technical Characteristics

• Material: Carbon steel (Grade 8.8 or 10.9) or stainless steel (A2/304, A4/316) options available.

• Heat treatment: Quenched and tempered for high-tensile carbon grades; solution annealed for stainless options.

• Mechanical properties: Typical tensile strength — Grade 8.8: ≥ 800 MPa; Grade 10.9: ≥ 1,000 MPa.

• Hardness: Carbon high-tensile: HRC approx. 30–38 (depending on grade); stainless per specification.

• Threading: Fully threaded to the shank according to ISO metric coarse thread series (M6–M36 commonly stocked).

• Dimensional tolerance: Manufactured to ISO 4017 tolerances for thread pitch, length, and head geometry.

• Corrosion protection: Plain, zinc plated (6–12 µm), hot-dip galvanized, and various passivations for stainless (electropolish available).

• Finish/color: Natural metal, yellow zinc, clear zinc, black oxide, or bright stainless finish.

• Form factor: Hex head fully threaded bolt; lengths from standard stock to custom cut-to-length.

• Packaging: Small orders: polybagged with desiccant and labeled cartons; bulk: palletized on shrink-wrapped wooden pallets, bulk drums or steel crates available.

• Shelf life: Indefinite for metal fasteners when stored dry; recommended indoor storage to prevent surface corrosion.

• Inspection & certification: Supplied with batch traceability, material certificates (EN/ISO 10204 2.1/3.1 upon request), and dimensional inspection reports.

3. Core Industrial Applications

• Construction & Infrastructure: Used for structural steel connections, temporary and permanent scaffolding tie-ins, and anchor assemblies where full thread engagement and adjustability are required.

• Oil & Gas & Petrochemical: Secures pipe supports, pressure-vessel mounts, and skids where high tensile strength and reliable torque-tension behavior are critical.

• Mining & Heavy Machinery: Fastening of conveyor frames, crushers, and mobile equipment where fatigue resistance and consistent clamping reduce downtime.

• Power Generation & Utilities: Turbine and generator ancillary assemblies, cable tray and support systems where standardized fasteners improve maintenance efficiency.

• OEM & Industrial Fabrication: Machinery assembly lines and custom equipment manufacturing benefiting from ease of inventory management and interchangeability.
  Why it outperforms alternatives: Fully threaded ISO 4017 bolts offer maximum thread engagement, superior adjustability, and compatibility with standardized nuts and washers, reducing the need for custom fasteners and lowering installation time. High-grade material and controlled heat treatment deliver better fatigue life and predictable preload retention compared with unspecified or locally produced fasteners.

4. Competitive Advantages

• Quality consistency: Manufactured to ISO tolerances with batch-level material certification and dimensional inspection to reduce field failures.

• Supply reliability: Production capacity for continuous bulk supply, safety-stock management, and scheduled replenishment for megaproject timelines.

• Logistics capability: Export-ready packaging, pallet optimization for container loading, and global freight partnerships enabling door-to-door options.

• Price competitiveness: Economies of scale for bulk MOQs, transparent tiered pricing, and cost modeling support for total-cost-of-ownership decisions.

• Sustainability: Material sourcing controls, recyclable metal packaging options, and processes to minimize waste in production.

• Technical support: Engineering data sheets, torque-tension guidance, installation best practices, and access to certificates (material test reports, inspection) for QA/QC teams.

5. Commercial & Supply Information

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

• Loading capacity: Typical container loading (approximate, subject to packaging and size mix): 20 ft container ≈ 20 MT; 40 ft container ≈ 24–26 MT (palletized).

• Lead times: Standard stock selections ship within 2–4 weeks; custom grades or finishes quoted per order.

• Terms: Export documentation, INS, and certificates provided per request; packaging tailored to project requirements.
