Applications & Industries

Where Hilti HUS4 Concrete Screw Anchors are used, and what decides the specification in each case. Stocked from 8 to 16 (nominal diameter).

Industries that specify Hilti HUS4 Concrete Screw Anchors

  • Electrical services Conduit, tray and support brackets fixed directly to concrete.
  • Window and door installation Frames attached to concrete or masonry reveals with a removable screw anchor.
  • Temporary works Formwork rails, guards and fixtures installed and removed without an expansion sleeve.
  • Equipment support Light and medium brackets anchored to a concrete slab.
  • Construction & structural Base plates, brackets and steelwork fixed to concrete.
  • Building services Suspending tray, duct, pipe and sprinkler runs from a soffit.

Typical applications

  • cutting a mating thread directly into a prepared concrete hole
  • installing a removable fixing without a separate expansion plug
  • matching drill diameter and embedment to the selected HUS4 configuration
  • checking edge distance, spacing and concrete condition against the approval
  • fixing a steel fixture through to a solid substrate
  • suspended services on threaded rod

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.
The concrete governs
Capacity is a property of the base material and the geometry — grade, edge distance, spacing and cracked or uncracked — not of the anchor alone. Work to the anchor manufacturer's ETA or ICC-ES report.
Hole preparation
Drilled diameter, depth and cleanliness are part of the specification; an uncleaned hole is the single most common cause of a failed anchor.

Where to use something else

  • Do not replace the approved drill and embedment values with a generic masonry-screw rule.
  • Not for a substrate the type is not qualified in — an expansion anchor near an edge or in hollow block will split it.

Manufactured to Trade series (Hilti HUS4), Hilti HUS4 Concrete Screw Anchors are anchors & concrete fixings supplied by Engineering Hardware. The dimensional data, materials and selection notes are summarized here.

What Are Hilti HUS4 Concrete Screw Anchors?

Hilti HUS4 Concrete Screw Anchors are anchors & concrete fixings defined by Trade series (Hilti HUS4). They are selected by nominal diameter and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.

Pricing

Hilti HUS4 Concrete Screw Anchors are supplied to order. Pricing starts from approximately US$1.80 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

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.
