ISO Custom Machined Component Dimensions

ISO Custom Machined Component Dimensions reference image

Specification summary of ISO as applied to custom machined component: the dimensions the standard controls, the tolerance and product grades it defines, the full specified size range, and the equivalent DIN/ISO/ASME designations.

ISO — Scope

ISO specifies the dimensions and tolerances of custom machined component — iso / din (series 130). 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, alongside the related ISO / DIN 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 controls only the geometry of custom machined component — iso / din (series 130). 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

Choose ISO for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for custom machined component — iso / din (series 130).

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 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 last revise its dimensional table?

ISO standards for custom machined component — iso / din (series 130) 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 specify for Custom Machined Component — ISO / DIN (Series 130)?

ISO specifies the dimensions and tolerances of custom machined component — iso / din (series 130). Material and property class are governed by separate standards in the same family.

What product grades does ISO define?

ISO typically distinguishes product grades for precision (A/B) and general engineering (C). The selection for Custom Machined Component — ISO / DIN (Series 130) depends on the precision your application requires.
