DIN Custom Machined Component Dimensions

DIN Custom Machined Component Dimensions reference image

Specification summary of DIN 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.

DIN — Scope

DIN 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

DIN, 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.

Equivalent Standards

Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Custom Machined Component — ISO / DIN (Series 130) page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.

Companion Standards

DIN 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).

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 DIN 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 DIN 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 DIN specify for Custom Machined Component — ISO / DIN (Series 130)?

DIN 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 DIN define?

DIN 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.
