GOST 9150-2002 PDF

Full title and description

GOST 9150-2002 — Основные нормы взаимозаменяемости. Резьба метрическая. Профиль (Basic norms of interchangeability — Metric screw threads — Profile). This interstate (GOST) standard defines the basic thread profile and associated nominal parameters for metric screw threads used in engineering and manufacturing across participating states.

Abstract

GOST 9150-2002 establishes the fundamental profile geometry and dimensional principles for general-purpose metric screw threads to ensure interchangeability of threaded parts. It specifies the basic profile form, key dimensions and tolerances (as required for a basic profile definition), and references international practice (ISO 68-1). The standard is intended as the normative reference for designing, manufacturing and inspecting metric threads within the scope of GOST/interstate technical regulation.

• ICS / categories: 21.040.10 — Mechanical systems and components; screw threads; metric screw threads.
• Edition / version: GOST 9150-2002 (first interstate edition under this designation; aligned with ISO 68-1:1998 references).
• Number of pages: 7–8 pages (typical published text length; page count varies slightly by publisher/format).

Scope

The standard applies to general-purpose metric threads and defines the basic thread profile (form and nominal dimensions) used as the reference for design and manufacture. It covers the geometric form of the profile, the nominal angles and radii that characterise the basic metric thread form, and its role as the reference profile for interchangeability rules; it does not detail all tolerance classes or application-specific limits (those are given in complementary standards).

Key topics and requirements

• Definition of the basic (fundamental) metric thread profile (geometry, included angle, crest/root forms).
• Nominal dimensions and proportions for the basic profile (as the reference for sizing and measurement).
• Reference to international practice (alignment with ISO 68-1 where applicable).
• Normative role of the basic profile for ensuring interchangeability between mating threaded parts.
• Normative references and related GOST standards that specify tolerances, pitches and application-specific thread forms.

Typical use and users

Mechanical design and development engineers, fastener and threaded-component manufacturers, metrology and quality-control laboratories, standards and certification bodies, tooling and gauge producers, and purchasers of threaded parts use this standard as the baseline definition of the metric thread profile for design, production and inspection to ensure interchangeability.

Related standards

Typical related documents include the predecessor national standard (GOST 9150-81), ISO 68-1 (metric screw threads — basic profile), and other complementary GOST/ISO standards that define thread tolerances, pitches and special thread forms (for example standards covering tolerances, thread gauges, and specific fastener types such as those listed in national catalogs).

FAQ

Q: What is this standard?

A: GOST 9150-2002 is an interstate standard that defines the basic (fundamental) profile for general-purpose metric screw threads to ensure interchangeability of threaded parts across participating countries.

Q: What does it cover?

A: It covers the geometric form and nominal parameters of the basic metric thread profile (angles, crest/root definitions, and related nominal dimensions). It serves as the normative reference for the thread profile; detailed tolerances and application-specific requirements are provided in complementary standards.

Q: Who typically uses it?

A: Mechanical designers, fastener manufacturers, metrology and inspection labs, tooling/gauge makers, procurement specialists and conformity assessment bodies use it as the baseline definition for metric thread geometry and interchangeability.

Q: Is it current or superseded?

A: GOST 9150-2002 is the 2002 interstate edition and is listed as active in national registries. It superseded earlier national versions (for example GOST 9150-81 in part) and aligns with ISO 68-1. Users should check their national standards body for the current legal status in a specific country and for any amendments.

Q: Is it part of a series?

A: Yes — it is part of the family of standards governing screw threads and interchangeability (including earlier GOST editions and complementary standards that specify tolerances, gauges, pitches and application-specific thread requirements). It also references and aligns with ISO 68-1 for the basic profile.

Q: What are the key keywords?

A: Metric thread, thread profile, basic profile, interchangeability, GOST, ISO 68-1, screw thread, fastener geometry.
