Full title and description

ISO 8764-2:2004 — Assembly tools for screws and nuts — Screwdrivers for cross-recessed head screws — Part 2: General requirements, lengths of blades and marking of hand-operated screwdrivers (Edition 2, 2004). This part specifies the general requirements, standard blade lengths and marking conventions for hand-operated screwdrivers intended for H and Z cross‑recessed head screws.

Abstract

Specifies general requirements, lengths of blades and marking of hand-operated screwdrivers for H and Z cross-recessed head screws as defined in ISO 4757; blade-tip geometry and dimensions are covered in ISO 8764-1. The document is a short technical specification (4 pages) that complements the driver-tip requirements given in Part 1.

Scope

Defines the applicable general requirements for hand-operated screwdrivers designed to engage H and Z cross‑recesses (as specified in ISO 4757), sets standard blade lengths for hand drivers and specifies the marking required on hand‑operated screwdrivers to identify tip form and relevant dimensions. For blade-tip shapes and dimensional details the purchaser or manufacturer must also refer to ISO 8764-1.

Key topics and requirements

• General dimensional and performance requirements for hand-operated screwdrivers intended for cross‑recessed screws.
• Standardised lengths of blades for hand drivers (specified size ranges and recommended blade lengths to ensure correct engagement and handling).
• Marking requirements for hand-operated screwdrivers (identification of tip form H or Z and other marking conventions so users can identify driver type and size).
• Reference to ISO 8764-1 for driver tip geometry and dimensional tolerances.
• Applicability to cross‑recess types H and Z as defined in ISO 4757.

Typical use and users

Used by screwdriver and hand-tool manufacturers, product designers, quality and compliance engineers, procurement specialists and test laboratories to specify, manufacture, mark and verify hand screwdrivers for cross‑recess screws. Also used by maintenance engineers and purchasers who require standardised driver sizes and clear marking for tool sets.

Related standards

FAQ

Q: What is this standard?

A: ISO 8764-2:2004 is the part of the ISO 8764 series that sets general requirements, blade lengths and marking rules for hand-operated screwdrivers used with H and Z cross-recessed head screws.

Q: What does it cover?

A: It covers general requirements for hand screwdrivers (dimensions of blades/lengths for hand drivers), how tools should be marked to indicate tip form and sizing, and the applicability to H and Z cross‑recess types; blade‑tip profiles themselves are defined in ISO 8764-1.

Q: Who typically uses it?

A: Tool manufacturers, design and product engineers, quality assurance and conformity assessment bodies, procurement teams specifying tool sets, and maintenance organisations that require standardised drivers. (Use case summary based on the standard's scope and audience.)

Q: Is it current or superseded?

A: ISO 8764-2:2004 (Edition 2) is published and has been subject to ISO systematic review; the ISO catalog indicates this edition has been reviewed and confirmed, and remains the current version. Users should check the ISO catalogue for the latest confirmation or revision status before purchase or formal citation.

Q: Is it part of a series?

A: Yes — ISO 8764 is a multi-part series. Part 1 (ISO 8764-1:2004) covers driver tips (shape, dimensions and tests) while Part 2 (this document) covers general requirements, blade lengths and marking for hand‑operated screwdrivers.

Q: What are the key keywords?

A: Screwdriver, cross‑recess, H, Z, blade length, marking, driver tip, ISO 8764, ISO 4757, hand tool specification.
