What Are Large Round Head Nails for Wood Wool Panels Used For?

Typical applications, the industries that specify large round head nails for wood wool panels, and how to choose the right size, material and finish for the joint.

Large Round Head Nails for Wood Wool Panels are used for nails with a 20 mm round head for fixing wood wool composite panels. They are manufactured to DIN 1144, and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

Large Round Head Nails for Wood Wool Panels are used primarily for nails with a 20 mm round head for fixing wood wool composite panels. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to DIN 1144. Stocked across roughly 31 mm to 34 mm, they cover heavy and structural work.

Typical Applications for Large Round Head Nails for Wood Wool Panels

The most common settings where these are specified:

  • Building insulation: wood wool panels.
  • Acoustic panels: fixing to timber.
  • Plaster base: panel fixing.
  • Renovation: insulation boards.

How to Specify Large Round Head Nails for Wood Wool Panels for Your Application

  • Size: Select on nominal diameter, then on the hole tolerance and fit class — the fit, not the diameter alone, determines whether the part locates or slips. This product spans 31 mm–34 mm; check the full table below for the exact dimensions of each size.
  • Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
  • Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
  • Standard: This product is supplied to DIN 1144. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Where Large Round Head Nails for Wood Wool Panels Are Not the Right Choice

Not for joints needing later removal or high withdrawal resistance — a screw holds far better in tension.

Custom manufacturing · Made to drawing

Need a large round head nails for wood wool panels outside the standard range?

Dimensions, material, finish and form are specified from the drawing — a nail outside the standard range is a variation on existing tooling rather than a new design.

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

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
    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
    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
    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
    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

What are Large Round Head Nails for Wood Wool Panels used for?

Nails with a 20 mm round head for fixing wood wool composite panels. They are supplied to DIN 1144.

Which industries use Large Round Head Nails for Wood Wool Panels?

They are commonly specified in plaster base, renovation and building insulation, among other sectors.

How do I choose the right size of Large Round Head Nails for Wood Wool Panels?
