Full title and description

ISO 3193:2008 — Aerospace — Bolts, normal hexagonal head, normal shank, short or medium length MJ threads, metallic material, coated or uncoated, strength classes less than or equal to 1 100 MPa — Dimensions. This International Standard specifies the dimensional requirements for normal hexagonal‑head bolts intended for aerospace applications and for inclusion in aerospace product standards.

Abstract

ISO 3193:2008 defines configuration and dimensional limits for normal hexagonal‑head bolts with normal shank and short or medium MJ threads, covering coated or uncoated metallic materials and bolts with strength classes up to 1 100 MPa. It is intended to be used when compiling aerospace product standards and related procurement or design documents.

Scope

Specifies the configuration and dimensions for normal hexagonal‑head bolts with normal shank and short or medium MJ threads in metallic material (coated or uncoated) where tensile strength classification is less than or equal to 1 100 MPa. The standard is intended for use in aerospace product standards and for designers, procurers and manufacturers who need consistent dimensional definitions for these bolt types.

Key topics and requirements

• Dimensional definitions for normal hexagonal head bolts (head geometry, shank diameter and lengths).
• MJ thread specification: short or medium length MJ threads appropriate for aerospace fasteners.
• Shank tolerance classes (close or large tolerance normal shank) and related dimensional limits.
• Application to metallic materials, whether coated or uncoated, and classification by strength (≤ 1 100 MPa).
• Compatibility with aerospace product standards and use as a reference for procurement drawings and acceptance documents.

These topics and technical limits are summarized from the standard's scope and configuration clauses.

Typical use and users

Typical users include aerospace designers and engineers, fastener manufacturers, procurement and quality assurance personnel in the aerospace supply chain, and standards authors preparing aerospace product standards or procurement specifications that reference bolt dimensions and thread forms. The standard is used as a dimensional reference when specifying or verifying MJ‑thread hex‑head bolts for aerospace assemblies.

Related standards

Standards commonly referenced alongside ISO 3193:2008 include other aerospace bolt and fastener specifications (procurement and material‑specific standards) such as ISO procurement specifications and material‑specific MJ thread bolt standards (examples include contemporary ISO documents addressing MJ‑thread bolts and procurement requirements). See recent ISO aerospace bolt documents (e.g., ISO 7689 and ISO 9154) for complementary procurement and material requirements.

FAQ

Q: What is this standard?

A: ISO 3193:2008 is an International Standard that specifies dimensions for normal hexagonal‑head bolts with normal shank and short or medium MJ threads intended for aerospace use.

Q: What does it cover?

A: It covers bolt geometry and dimensional limits (head, shank, thread length and related tolerances) for metallic hex‑head bolts (coated or uncoated) classified up to 1 100 MPa tensile strength, for use in aerospace product standards and documentation.

Q: Who typically uses it?

A: Aerospace engineers, fastener manufacturers, procurement and quality personnel, and standards writers who need a consistent dimensional reference for MJ‑thread hex‑head bolts used in aerospace applications.

Q: Is it current or superseded?

A: The 2008 second edition is the published ISO edition; ISO's bibliographic record indicates this edition and shows subsequent ISO review activity (the ISO bibliographic entry for the standard indicates it was reviewed/confirmed in later ISO reviews). Users should check ISO or their national body for any amendments or later revisions when applying the standard.

Q: Is it part of a series?

A: ISO 3193:2008 is part of the broader set of aerospace fastener standards developed under ISO/TC 20/SC 4; related documents address procurement, material and strength‑class requirements for MJ‑thread bolts and other aerospace fasteners. Examples include ISO procurement and material standards for MJ‑thread bolts.
