What Are Hilti HUS4 Concrete Screw Anchors Used For? application image

Hilti HUS4 Concrete Screw Anchors (Trade series (Hilti HUS4)) are specified where the joint requires direct-thread concrete fixing in a prepared drilled hole. The sections below cover the typical end-uses by industry, the size and material decisions for each, assembly practice, and the applications this fastener type is not suited to. Stocked across roughly 8 mm to 16 mm, they cover general to heavy-duty work.

Typical Applications for Hilti HUS4 Concrete Screw Anchors

The most common settings where these are specified:

  • Electrical services: conduit, tray and support brackets fixed directly to concrete.
  • Window and door installation: frames attached to concrete or masonry reveals.
  • Temporary works: formwork rails, guards and fixtures installed and removed quickly.
  • Equipment support: light and medium brackets anchored to a concrete slab.

How to Specify Hilti HUS4 Concrete Screw Anchors for Your Application

  • Size: Match the nominal size to the mating thread or hole. This product spans 8 mm–16 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 Trade series (Hilti HUS4). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Where Hilti HUS4 Concrete 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.

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.
