Full title and description

Assembly tools for screws and nuts — Double-headed box wrenches, deep offset and modified offset — Outside dimensions (ISO 10104:2018). This international standard specifies outside dimensions (overall length and maximum head thickness) for double-headed box wrenches in deep-offset (Form B) and modified-offset (Form A) designs.

Abstract

ISO 10104:2018 (Edition 3) defines the overall length and the maximum head thickness for specified double-headed box wrenches (deep offset and modified offset). It identifies the wrench types by reference to ISO 1703:2005 and notes that technical specifications (material, hardness, test torques, etc.) are given in ISO 1711‑1 (series A). The edition was confirmed in a 2023 review and remains current.

Scope

ISO 10104:2018 applies to double-headed box wrenches of the deep-offset (Form B) and modified-offset (Form A) types. The document specifies only outside dimensions (overall length and maximum head thickness) for the wrench types identified by reference numbers in ISO 1703:2005; it does not set material or mechanical performance requirements, which are given in ISO 1711‑1 (series A).

Key topics and requirements

• Definition of covered wrench forms: deep offset (Form B) and modified offset (Form A).
• Specified outside dimensions: overall length and maximum head (box) thickness for each nominal size/form.
• Identification of covered wrench types by reference to ISO 1703:2005 reference numbers.
• Clarification that technical specifications (hardness, torsional strength, test torques, etc.) are handled in ISO 1711‑1 (series A), not within ISO 10104.
• Intended use for standardizing external envelope dimensions to ensure interchangeability, clearance and compatibility with assemblies and storage systems.

Primary normative points above are summarized from the ISO 10104:2018 abstract and scope.

Typical use and users

Manufacturers of hand tools, tool designers, quality and compliance engineers, procurement teams, testing laboratories and standards committees use ISO 10104 when specifying, producing or verifying double-headed box wrenches to ensure consistent outside dimensions and compatibility with related tooling and storage systems.

Related standards

Standards directly referenced or closely related to ISO 10104:2018 include ISO 1703:2005 (tool identification/reference numbers for wrench types) and ISO 1711‑1 (technical specifications for hand-operated wrenches and sockets — series A). Other ISO standards in the "Assembly tools for screws and nuts" series (e.g., ISO 10103, ISO 3318, ISO 1085) address complementary dimension, torque and pairing requirements.

FAQ

Q: What is this standard?

A: ISO 10104:2018 is an international standard that specifies the outside dimensions (overall length and maximum head thickness) for double-headed box wrenches in deep-offset (Form B) and modified-offset (Form A) configurations.

Q: What does it cover?

A: It covers only outside dimensional requirements (overall length and maximum head thickness) for the named wrench types. It does not set material, hardness or mechanical performance requirements; those are covered in ISO 1711‑1 (series A).

Q: Who typically uses it?

A: Tool manufacturers, product designers, procurement and quality engineers, independent test labs and standards bodies use ISO 10104 to ensure consistent external dimensions and interoperability of hand wrenches. (See related ISO tool-series standards for mechanical/specification requirements.)

Q: Is it current or superseded?

A: ISO 10104:2018 is the current edition (Edition 3, published March 2018) and was reviewed/confirmed in 2023; it replaced ISO 10104:2001.

Q: Is it part of a series?

A: Yes — ISO 10104 belongs to the “Assembly tools for screws and nuts” family of ISO standards (other related documents include ISO 10103, ISO 3318, ISO 1711‑1, ISO 1085, ISO 1703 for reference numbering, etc.).

Q: What are the key keywords?

A: Assembly tools, hand tools, double-headed box wrench, deep offset, modified offset, outside dimensions, ISO 10104, tool dimensions.
