Applications & Industries for M10 Hilti HDA-T Self-Undercutting Mechanical Anchors

What Hilti HDA-T Self-Undercutting Mechanical Anchors are specified for, industry by industry. Stocked from M10 to M20.

Industries that specify Hilti HDA-T Self-Undercutting Mechanical Anchors

  • Plant installation Machine hold-downs where edge distance and spacing need design control.
  • Infrastructure maintenance Anchored rails, barriers and brackets in existing concrete.
  • Concrete base plates Post-installed threaded anchors for steel columns and equipment frames.
  • Bridge retrofit Removable structural attachments installed in existing cracked concrete.
  • Plant installation Machines and equipment held down to a concrete floor.
  • Fit-out & drylining Fixings into board, block and hollow wall.

Typical applications

  • using an externally threaded fixing where the fixture may be removed
  • selecting the installation from the applicable Hilti approval or design report
  • creating a mechanical undercut in a drilled concrete hole
  • installing a threaded anchor with a specified embedment and fixture thickness
  • suspended services on threaded rod
  • making a load-bearing threaded fixing in concrete or masonry

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 use the catalog series options as an allowable load table; the approval controls concrete condition and capacity.
  • Not for a substrate the type is not qualified in — an expansion anchor near an edge or in hollow block will split it.

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 clearance and tapping drill suit M10?

Use a 11 mm clearance hole (ISO 273 medium) for through-fixing, or a 8.5 mm tapping drill for a coarse M10 thread.

What is the coarse-thread pitch of M10 for Hilti HDA-T Self-Undercutting Mechanical Anchors?

For M10 the standard coarse pitch is 1.5 mm — this is the value used for Hilti HDA-T Self-Undercutting Mechanical Anchors.
