Full title and description

Assembly tools for screws and nuts — Screwdrivers for cross-recessed head screws — Part 1: Driver tips (ISO 8764-1:2004). This part specifies the shapes and dimensions, technical requirements and torque test methods for the tips of hand drivers and of machine-operated bits for cross‑recessed head screws; it defines two tip forms (PH and PZ) and references related requirements in other parts of the series.

Abstract

ISO 8764-1:2004 defines the geometry and dimensional limits, performance requirements and torque test procedures for driver tips intended to engage cross‑recessed (cruciform) screw heads. It distinguishes form PH (for form H recesses) and form PZ (for form Z recesses) and gives the basis for conformity testing of tips used in hand and machine drivers.

Scope

Specifies shapes, nominal dimensions and tolerances, material/performance-related technical requirements where applicable, and torque testing methods for driver tips used with cross‑recessed head screws. The standard applies to tips for hand drivers and machine-operated bits and identifies two standard tip forms (PH and PZ); it refers to ISO 4757 for recess form definitions and to ISO 8764-2 for general requirements such as blade lengths and marking of hand-operated screwdrivers.

Key topics and requirements

• Defined tip geometries and dimensional tolerances for cross‑recessed driver tips (PH and PZ forms).
• Technical requirements addressing fit, strength and functional performance of tips used in hand and machine drivers.
• Torque test methods to verify driver‑tip engagement and endurance under specified loading.
• References to related specifications: ISO 4757 (recess forms) and ISO 8764-2 (general requirements for screwdrivers).

Typical use and users

Used by tool manufacturers (design and production of screwdriver tips and bits), quality and conformity testing laboratories, procurement specialists specifying tool requirements, product designers and maintenance engineers who need consistent driver/screw interfaces, and standards committees aligning national/adopted versions. The standard helps ensure interchangeability and reliable torque transfer between drivers and cross‑recessed screws.

Related standards

Related documents and parts include ISO 8764-2 (general requirements, blade lengths and marking of hand-operated screwdrivers) and ISO 4757 (definitions of recess forms H and Z). ISO 8764-1:2004 is a revision in the ISO 8764 series (replacing earlier editions such as the 1999 version).

FAQ

Q: What is this standard?

A: ISO 8764-1:2004 is the part of the ISO 8764 series that specifies driver tips for cross‑recessed head screws — covering shapes, dimensions, technical requirements and torque test methods for tips used in hand and machine drivers.

Q: What does it cover?

A: It covers the geometry and dimensional tolerances for driver tips (forms PH and PZ), performance/technical requirements related to fit and function, and prescribed torque test methods to assess tip engagement and durability. It does not cover full screwdriver blade lengths and marking, which are in ISO 8764-2.

Q: Who typically uses it?

A: Tool manufacturers, quality and testing laboratories, procurement and specification engineers, product designers, and maintenance teams — any organization needing standardized driver‑to‑screw interfaces and verified torque performance.

Q: Is it current or superseded?

A: ISO 8764-1:2004 is the current published edition (Edition 3, 2004). The ISO record shows this edition was subject to periodic review and was confirmed as current during the most recent systematic review cycle.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 8764 series (assembly tools for screws and nuts — screwdrivers for cross‑recessed head screws). Part 2 and other related documents cover complementary topics such as general requirements, blade lengths and marking.

Q: What are the key keywords?

A: Driver tips, screwdriver, cross‑recessed, PH, PZ, torque test, ISO 8764, assembly tools.
