ISO4017 Class 4.8 and Hexagon Head Bolts
ISO4017 Class 4.8 hexagon head bolts from Ningbo Steel Bolt Co., Ltd are carbon steel fasteners manufactured to international standards, with fine thread options and heat-treated grades including 4.8, 6.8, 8.8, 10.9 and 12.9 to suit varying load requirements. The bolts are supplied with surface treatments such as hot-dip galvanizing, zinc plating, black oxide and Dacromet to enhance corrosion resistance for industrial and structural use. Standard hex heads ensure compatibility with common tools, while the fine thread design provides higher torque control in critical applications.
The material range includes carbon steel as a base, with optional stainless steel for environments requiring superior resistance to rust or chemical exposure. Heat treatment is applied to achieve the specified class, with Class 4.8 offering a typical tensile strength of 400 MPa and yield strength of 320 MPa, standard for general-purpose fastenings. Surface finishes like HDG and Dacromet are typical for outdoor or marine applications where prolonged exposure to moisture or salt is expected.
These bolts are widely used in machinery, automotive assembly, construction frameworks and engineering projects, particularly where vibration resistance and reliable clamping force are required. Bulk packaging is standard for OEM and aftermarket supply chains, with custom designs and branding available on request. Buyers typically source these for structural joints, equipment mounting and heavy-duty connections in industrial settings.

Sourcing ISO4017 Class 4.8 and Hexagon Head Bolts from Ningbo Steel Bolt Co., Ltd - China Import Guide
Before placing an order, verify the exact class and material specifications required for your application, as mismatches in tensile strength or corrosion resistance can lead to structural failures. Confirm whether fine thread is suitable for your design, or if coarse thread variants are needed for compatibility with existing components.
Discuss logistics details such as lead time, which may vary depending on the order volume and custom requirements like surface treatment or branding. Clarify Incoterms, particularly whether the supplier operates on FOB Ningbo or CIF terms, and agree on payment methods such as T/T or L/C to avoid delays in shipment.
Request quality inspection certificates, including material test reports and surface treatment compliance, to ensure the bolts meet ISO4017 standards. Conduct random sampling for dimensional accuracy and perform torque tests on a sample batch to validate the mechanical properties, especially for critical applications in automotive or construction.
