What Are Commercial Ground Screw Anchors Used For?

Typical applications, the industries that specify commercial ground screw anchors, and how to choose the right size, material and finish for the joint.

Commercial Ground Screw Anchors are used for creating a threaded base point in soil for signs, plates and temporary outdoor structures. They are manufactured to Trade series (commercial ground screw anchors), and selection is driven by the size designation, the fit and tolerance the assembly requires, and the service environment.

What Are Commercial Ground Screw Anchors Used For? application image

Commercial Ground Screw Anchors are used primarily for creating a threaded base point in soil for signs, plates and temporary outdoor structures. 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 Trade series (commercial ground screw anchors).

Typical Applications for Commercial Ground Screw Anchors

The most common settings where these are specified:

  • Sign installation: Commercial ground screws provide a threaded top for signs and base plates.
  • Outdoor equipment: Galvanized steel anchors support temporary structures and equipment.
  • Event structures: 450–900 mm shaft lengths suit different ground engagement needs.
  • Landscape construction: Hex and hexless threaded-top forms support field installation.

How to Specify Commercial Ground Screw Anchors for Your Application

  • Size: Match the size to the mating part — see the dimension table below for each option.
  • 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 Trade series (commercial ground screw anchors). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Where Commercial Ground Screw Anchors Are Not the Right Choice

Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.

Technical Drawing

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 Commercial Ground Screw Anchors used for?
