Applications & Industries
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 installationMachine hold-downs where edge distance and spacing need design control.
Infrastructure maintenanceAnchored rails, barriers and brackets in existing concrete.
Concrete base platesPost-installed threaded anchors for steel columns and equipment frames.
Bridge retrofitRemovable structural attachments installed in existing cracked concrete.
Plant installationMachines and equipment held down to a concrete floor.
Fit-out & dryliningFixings 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.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Hilti HDA-T Self-Undercutting Mechanical Anchors (Trade series (Hilti HDA-T)) are a type of anchors & concrete fixings used across industrial assembly. Below is the complete size table together with material, standard and application guidance.
What Are Hilti HDA-T Self-Undercutting Mechanical Anchors?
Hilti HDA-T Self-Undercutting Mechanical Anchors are anchors & concrete fixings defined by Trade series (Hilti HDA-T). They are selected by thread size 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 HDA-T Self-Undercutting Mechanical Anchors are supplied to order. Pricing starts from approximately US$4.00 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.
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.
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.
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.
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.
