Описание (английский):

ISO 8764-1:2004 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 specifies two forms of driver tips: form PH for form H recesses and form PZ for form Z recesses. (H and Z form recesses are specified in ISO 4757, while general requirements, lengths of blades and marking of hand-operated screwdrivers are given in ISO 8764-2.)

Overview

ISO 8764-1:2004 - "Assembly tools for screws and nuts - Screwdrivers for cross-recessed head screws - Part 1: Driver tips" defines the shapes, dimensions, technical requirements and torque test methods for screwdriver tips used with cross‑recessed head screws. It covers two tip forms: PH (for form H recesses) and PZ (for form Z recesses). The standard establishes geometric profiles, inspection methods (gauges), material and heat‑treatment requirements, surface finish expectations, and torque‑resistance testing for both hand-operated and machine-operated bits.

Key Topics

Tip forms and dimensions

Two standardized forms: PH and PZ with sizes (e.g., 0–4) specified by figures and tables for blade diameters, angles and flute geometry.
Axis concentricity requirement; dimensions must be met after plating if a finish is applied.

Material, heat treatment and hardness

Steel suitable for hardening and tempering.
Minimum hardness: 54 HRC for hand-operated tips, 58 HRC for machine-operated tips, for a length equal to three times the nominal blade diameter from the driving end. Remaining tool sections: minimum 50 HRC.
Test block hardness for torque testing: 62 HRC minimum.

Inspection and gauges

Dimensional conformity checked by direct measurement or by inspection gauges (detailed in Clause 5, Annex A and B). Gauges ensure correct penetration and profile fit to screw heads.

Torque testing

Defined torque test procedure using a torque‑testing device and a corresponding test block. Tips must show no fracture or permanent distortion after applying specified minimum torques.
Test torque scales with tip diameter; hand-test formula provided (M = 0.038 × d, where d = nominal blade diameter in mm).

Designation

Standardized labelling examples: e.g., "Tip ISO 8764-1 - PH2" or "Gauge ISO 8764-1 - PZ2".

Applications

Ensures interchangeability and reliable fit of screwdriver tips with cross‑recessed screws in manufacturing, maintenance and assembly.

Used by:

Tool manufacturers (design, production, marking),
Quality control and testing laboratories (inspection gauges, hardness and torque tests),
OEMs and procurement (specifying compliant tools for assembly lines),
Maintenance and repair operations requiring standardized driver performance.

Keyword relevance: screwdriver tips standard, cross‑recessed head screws, PH PZ driver tips, inspection gauges, torque test methods.

Related Standards

ISO 4757 - defines H and Z form recesses (screw head geometry) that correspond to PH and PZ driver tips.

ISO 8764-2 - complements Part 1 by giving general requirements, blade lengths and marking rules for hand-operated screwdrivers.

ISO 8764-1 is a practical reference for anyone specifying, producing or testing screwdriver tips for cross‑recessed screws to ensure correct fit, durability and torque performance.
