T 5782 Custom Machined Component Dimensions

T 5782 Custom Machined Component Dimensions reference image

For custom machined component, T 5782 defines the dimensions, tolerances and product grades. The sections below describe the scope of the document, the properties it deliberately leaves to companion standards, and the equivalent designations across standards bodies.

T 5782 — Scope

T 5782 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

T 5782, 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.

Companion Standards

T 5782 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).

When to Specify T 5782

Choose T 5782 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for custom machined component — gb/t 5782 / iso 4014 (series 004).

Frequently Asked Questions

What product grades does T 5782 define?

T 5782 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 T 5782 specify the mechanical strength?

No. T 5782 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 T 5782 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 T 5782 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.
