ISO 4032 Protective Shroud — GB/T 6170 / ISO 4032 (Series 064)

For Protective Shroud — GB/T 6170 / ISO 4032 (Series 064), ISO 4032 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 4032 — Scope

ISO 4032 specifies the dimensions and tolerances of protective shroud — gb/t 6170 / iso 4032 (series 064). 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 4032, alongside the related GB/T 6170 / ISO 4032 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.

Frequently Asked Questions

Can I substitute ISO 4032 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 4032 last revise its dimensional table?

ISO standards for protective shroud — gb/t 6170 / iso 4032 (series 064) 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 4032 specify for Protective Shroud — GB/T 6170 / ISO 4032 (Series 064)?

ISO 4032 specifies the dimensions and tolerances of protective shroud — gb/t 6170 / iso 4032 (series 064). Material and property class are governed by separate standards in the same family.

What is the equivalent of ISO 4032 in DIN or ASME?

ISO 4032 hex nuts correspond to DIN 934 (style 1).
