Specification summary of DIN 18182-2 as applied to drywall screws (bugle head): the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
DIN 18182-2 — Scope
DIN 18182-2 specifies the dimensional requirements for drywall screws (bugle head).
Material, surface condition and any performance rating are set by separate documents specific to this part family — ISO 898-1 and ISO 898-2, which govern bolt and nut property classes, do not apply here.
Tolerance & Product Grades
Tolerances for drywall screws (bugle head) are given as limits on the individual dimensions in the table rather than as a fastener product grade.
Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.
Dimensions Specified by DIN 18182-2
| Nominal diameter (mm) | Thread type | Pitch (mm) | Head diameter dk (mm) | Head height k (mm) | Drive | Common length range (mm) | Reference standard |
|---|---|---|---|---|---|---|---|
| 3.5 | Coarse (S), timber stud | 1.60 | 7.5 | 2.0 | PH2 | 25~55 | DIN 18182-2 |
| 3.5 | Fine (N), steel stud | 0.80 | 7.5 | 2.0 | PH2 | 25~45 | DIN 18182-2 |
| 3.9 | Coarse (S), timber stud | 1.80 | 8.0 | 2.2 | PH2 | 30~70 | DIN 18182-2 |
| 3.9 | Fine (N), steel stud | 0.85 | 8.0 | 2.2 | PH2 | 30~55 | DIN 18182-2 |
| 4.2 | Coarse (S), timber stud | 2.00 | 8.6 | 2.4 | PH2 | 45~90 | DIN 18182-2 |
| 4.8 | Coarse (S), timber stud | 2.20 | 9.5 | 2.6 | PH2 | 70~140 | DIN 18182-2 |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Drywall Screws (Bugle Head) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
DIN 18182-2 controls only the geometry of drywall screws (bugle head). Surface finish is governed by separate finish standards (for example ISO 4042 for electroplating), and corrosion testing by ISO 9227 (neutral salt spray). Mechanical performance is set by the standards specific to this part family, not by ISO 898-1 or ISO 898-2, which apply to bolts, screws and nuts.
