# DIN 18182-2 Drywall Screws (Bugle Head) Specification

Screws · DIN 18182-2

Dimensional table, tolerance classes and the DIN / ISO / ASME parts that supersede or match this standard.

DIN 18182-2 specifies the dimensions and tolerances for drywall screws (bugle head). The full dimensional table is reproduced below, followed by the DIN, ISO and ASME parts that match or supersede it.

- **Standard:** DIN 18182-2
- **Product:** Drywall Screws (Bugle Head)
- **Governing standards:** DIN 18182-2

Equivalence between national standards is dimensional, not always metallurgical. Check the property class separately when substituting.

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

The table below lists the dimensions catalogued for drywall screws (bugle head) under DIN 18182-2. The scope of DIN 18182-2 itself is not summarised here — where a figure matters, confirm it against the published document.

## Tolerance & Product Grades

Product grade is a concept from dimensional fastener standards and does not apply to DIN 18182-2. Tolerances for this part are the limits shown against each dimension in the table.

## 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

A complete specification for drywall screws (bugle head) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. DIN 18182-2 is one of them, not all of them.

Custom manufacturing · Made to drawing

## Need a screw to this standard in a non-standard size?

Parts built to DIN 18182 2 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by cold heading or warm forging.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

## Applications & Industries

What Drywall Screws are specified for, industry by industry. Stocked from 3.5 to 4.8 (screw size).

### Industries that specify Drywall Screws

- **Interior fit-out:** Boarding out timber and steel stud partitions.
- **Ceilings & linings:** Board fixed to furring channel and resilient bar.
- **Housebuilding:** Plasterboard and backing board through a whole plot.
- **Joinery & furniture:** Hardware, hinges and fittings into solid timber and wood-based board.
- **Roofing & cladding:** Profiled sheet and rainscreen fixed to purlins and rails.
- **Volume assembly:** Appliance and consumer products driven at speed with power tools.

### Typical applications

- fixing plasterboard so the head dimples the paper without cutting it
- coarse thread into timber studs, fine thread into steel studs
- driven with a depth-setting nose on a collated or single driver
- forming a thread directly in sheet, board or timber
- fixing where there is no access to add a nut behind the panel
- high-volume driving with a bit and a clutch-set driver

### Service conditions to specify against

- **Marine and coastal:** Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
- **Pilot hole:** Selection is really a hole-size decision: too small and the screw snaps or splits the material, too large and it strips. The size is stated per row.

### Where to use something else

- Phosphated screws are interior only — the black finish is a driving lubricant, not corrosion protection.
- Not for a joint that will be dismantled and reassembled repeatedly in the same hole — use an insert or a rivet nut instead.

Inside the plant

## Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift.
2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g.
3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1.
4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227.

## Frequently Asked Questions

### Can I substitute DIN 18182-2 for the corresponding DIN standard on a drawing?

On modern drawings the ISO standard is the master reference; the older DIN equivalent is a cross-reference. For most dimensional purposes the parts are interchangeable, but check tolerance grades and the head height — these are the most common points of divergence.

### Which edition of DIN 18182-2 does this table follow?

The table reproduces the dimensions we supply drywall screws (bugle head) to. We do not publish an edition year against it, so where the edition is contractually significant, cite the edition you require on the enquiry and we will confirm it against the table before quoting.

### How do I request a quotation?

Use the technical drawing on this page to pick the exact configuration, then submit it with the quote form. We respond within one business day.
