ISO 4014 Custom Machined Component — GB/T 5782 / ISO 4014 (Series 004)

Custom Machined Component — GB/T 5782 / ISO 4014 (Series 004) manufactured to ISO 4014 follow a specific scope. This page summarizes that scope, lists every dimension the standard fixes, and points to the most common cross-references.

ISO 4014 — Scope

ISO 4014 specifies the dimensions and tolerances of custom machined component — gb/t 5782 / iso 4014 (series 004). 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 4014, alongside the related GB/T 5782 / ISO 4014 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 4014 (partial thread) corresponds closely to DIN 931; the fully-threaded variant ISO 4017 corresponds to DIN 933.

Companion Standards

ISO 4014 controls only the geometry of custom machined component — gb/t 5782 / iso 4014 (series 004). 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).

Frequently Asked Questions

What product grades does ISO 4014 define?

ISO 4014 typically distinguishes product grades for precision (A/B) and general engineering (C). The selection for Custom Machined Component — GB/T 5782 / ISO 4014 (Series 004) depends on the precision your application requires.

Does ISO 4014 specify the mechanical strength?

No. ISO 4014 controls only the geometry of custom machined component — gb/t 5782 / iso 4014 (series 004). 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 4014 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 4014 last revise its dimensional table?

ISO standards for custom machined component — gb/t 5782 / iso 4014 (series 004) 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.
