Overview

ISO 10666:1999 defines the mechanical and functional properties required for heat‑treated drilling screws with a tapping screw thread (per ISO 1478) that incorporate a self‑drilling point. The standard ensures screws can drill their own core hole and form a mating thread without distortion or fracture under correct use. ISO 10666 is aimed at manufacturers, test laboratories, quality engineers and specifiers of self‑drilling fastening systems.

Key topics and requirements

Material: Case‑hardening steel or heat‑treatable steel is required for drilling screws.

Surface hardness: Minimum surface hardness after heat treatment is 530 HV 0,3 (Vickers).

Core hardness and tempering:

Core hardness ranges 320 HV to 400 HV (different test loads applied for threads ≤ or > ST 4,2).
A recommended minimum tempering temperature of 330 °C is specified; the range 275–315 °C should be avoided to reduce risk of tempered martensite embrittlement.

Case depth: Specified minimum and maximum case depths by nominal thread size (examples):

ST 2,9–ST 3,5: 0.05–0.18 mm
ST 4,2–ST 5,5: 0.10–0.23 mm
ST 6,3: 0.15–0.28 mm

Microstructure: No ferrite streaks between case and core after heat treatment.

Hydrogen embrittlement: Electroplated screws require risk management and testing (refer ISO 15330 and ISO 4042).

Functional tests:

Core drilling and thread forming: Screw point must drill the core hole and form mating thread under prescribed axial loads and speeds.
Torsional strength: Minimum torque to failure specified by thread size (e.g., ST 2,9 = 1.5 N·m, ST 6,3 = 16.9 N·m).

Test methods: Vickers hardness per ISO 6507‑1, metallography for case depth and microstructure, drilling + screwing‑in test using low‑carbon steel plates (≤0.23% C, hardness 110–165 HV30), and torsional testing with ±3% torque accuracy.

Applications and users

Fastener manufacturers and heat‑treaters - to design, heat‑treat and qualify drilling screws.

Electroplaters and coating suppliers - to manage hydrogen embrittlement and surface treatments.

Quality control and test laboratories - to perform Vickers hardness, microstructure and torsion/drilling tests.

Engineers and specifiers in construction, metal fabrication, HVAC, and appliance manufacturing - to select reliable self‑drilling fasteners and ensure compliance with performance criteria.
