ISO 4017 Hex Bolt, Fully Threaded — GB/T 5783 / ISO 4017 (Series 011)

For Hex Bolt, Fully Threaded — GB/T 5783 / ISO 4017 (Series 011), ISO 4017 defines dimensions, tolerances and product grades. The sections below describe its scope, what it does NOT cover, and the equivalents across DIN, ISO and ASME.

ISO 4017 — Scope

ISO 4017 specifies the dimensions and tolerances of hex bolt, fully threaded — gb/t 5783 / iso 4017 (series 011). 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.

Equivalent Standards

ISO 4017 (full thread) corresponds closely to DIN 933; the partially-threaded variant ISO 4014 corresponds to DIN 931.

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 hex bolt, fully threaded — gb/t 5783 / iso 4017 (series 011).

Technical Drawing

Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Frequently Asked Questions

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 hex bolt, fully threaded — gb/t 5783 / iso 4017 (series 011) 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 Hex Bolt, Fully Threaded — GB/T 5783 / ISO 4017 (Series 011)?

ISO 4017 specifies the dimensions and tolerances of hex bolt, fully threaded — gb/t 5783 / iso 4017 (series 011). Material and property class are governed by separate standards in the same family.

What is the equivalent of ISO 4017 in DIN or ASME?

ISO 4017 (full thread) corresponds closely to DIN 933; the partially-threaded variant ISO 4014 corresponds to DIN 931.
