ISO 8748 Spring (Roll) Pins

For Spring (Roll) Pins, ISO 8748 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 8748 — Scope

ISO 8748 specifies the dimensions and tolerances of spring (roll) pins. 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 8748, alongside the related ISO 8748 / DIN 1481 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 Spring (Roll) Pins page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.

When to Specify ISO 8748

Choose ISO 8748 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for spring (roll) pins.

Frequently Asked Questions

What does ISO 8748 specify for Spring (Roll) Pins?

ISO 8748 specifies the dimensions and tolerances of spring (roll) pins. Material and property class are governed by separate standards in the same family.

What product grades does ISO 8748 define?

ISO 8748 typically distinguishes product grades for precision (A/B) and general engineering (C). The selection for Spring (Roll) Pins depends on the precision your application requires.

Does ISO 8748 specify the mechanical strength?

No. ISO 8748 controls only the geometry of spring (roll) pins. 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 8748 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.
