ISO 4017 Custom Hex Bolt (GHJ Series) — GB/T 5783 / ISO 4017 (Series 009)

ISO 4017 is the international standard for custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009). This page sets out what the standard governs, the size range it specifies, and the related standards you will see referenced in datasheets.

ISO 4017 — Scope

ISO 4017 specifies the dimensions and tolerances of custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).

Tolerance & Product Grades

ISO 4017, alongside the related GB/T 5783 / ISO 4017 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.

Companion Standards

ISO 4017 controls only the geometry of custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009). The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).

When to Specify ISO 4017

Choose ISO 4017 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009).

Frequently Asked Questions

Does ISO 4017 specify the mechanical strength?

No. ISO 4017 controls only the geometry of custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009). The mechanical strength is set by ISO 898-1 (bolts / screws) or ISO 898-2 (nuts), and the finish is governed by separate standards.

Can I substitute ISO 4017 for the corresponding DIN standard on a drawing?

On modern drawings the ISO standard is the master reference; the older DIN equivalent is a cross-reference. For most dimensional purposes the parts are interchangeable, but check tolerance grades and the head height — these are the most common points of divergence.

When did ISO 4017 last revise its dimensional table?

ISO standards for custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009) are reviewed on roughly a five-year cycle. Always reference the latest published edition (or the edition cited contractually); the dimensional table on this page reflects the current commercially-supplied form.

What does ISO 4017 specify for Custom Hex Bolt (GHJ Series) — GB/T 5783 / ISO 4017 (Series 009)?

ISO 4017 specifies the dimensions and tolerances of custom hex bolt (ghj series) — gb/t 5783 / iso 4017 (series 009). Material and property class are governed by separate standards in the same family.
