Hammer-set family, exact construction first
Nail anchors are mechanical fixing enquiries described in manufacturer catalogues as nail-in or hammer-set forms for prepared holes. The name does not identify one universal construction. Select the exact product reference or controlled drawing before reviewing the substrate, fixture and setting requirements.
Do not merge different anchor mechanisms
| Selection field | What to provide |
|---|---|
| Drive-pin-style example | A body with an external bearing flange and a separate drive pin. The generic AI reference shows only this externally visible form, not hidden geometry or an installation sequence. |
| Nail-head/cone-and-clip example | Fischer describes its FNA II family with a cone and expansion clip and a load-controlled expansion mechanism. This is a maker-specific example, not the mechanism of every nail anchor. |
| Other mechanical anchors | Internally threaded drop-in anchors, sleeve anchors and stud-type wedge anchors have different interfaces and setting requirements. They are not renamed nail anchors. |
Prepared-hole anchors are not direct-fixing nails
Do not confuse this selector with powder-actuated or other direct-fixing nails driven into a substrate, drive rivets for joining a material stack, gypsum/hollow-wall fixings, cast-in anchor rods or adhesive anchoring systems. Ask for the selected construction and its documents when terminology is ambiguous.
Substrate and installation boundaries
No generic hole size, embedment, load, torque, fire resistance, cracked-concrete qualification or tool compatibility is stated. Solid concrete, hollow-core slabs, masonry and special conditions must not be treated as interchangeable. The responsible engineer and exact product documentation govern suitability and installation acceptance.
Quotation fields
| Selection field | What to provide |
|---|---|
| Exact construction | Manufacturer/product reference or controlled drawing and revision; drive-pin body or nail-head design, head form and supplied component list. Do not substitute on the word nail alone. |
| Body, pin and head | Body diameter and length datum, flange/head envelope, separate pin geometry and supplied position; selected drawing tolerances and units. |
| Substrate | Actual concrete or other specified substrate, condition and project requirements. A solid-concrete example does not establish suitability for hollow-core slabs, cracked concrete or special use. |
| Fixture and hole | Fixture material/thickness and clearance; drilling, hole depth, cleaning and embedment requirements only from the exact product documents and responsible design. |
| Setting and verification | Selected setting instructions, access, tool interface and required installed-condition verification. No universal hammer, drill-bit or setting-tool compatibility is promised. |
| Material and finish | Separate body/pin material, condition and finish requirements; exposure and requested inspection/traceability documents, without inferring them from the illustration. |
| Order package | Quantity in pieces or defined sets, controlled drawings and required project documents, packing, destination and requested timing; unresolved requirements listed for quotation review. |
Reference identity is not a standard or approval
HMH and FNA II are manufacturer product-family identifiers, not generic DIN/ISO standards or interchangeable specifications. Their published materials, dimensions, installation data and assessments apply to the identified manufacturer products. They do not establish conformity, brand affiliation, supply scope or performance for a FastenerBridge enquiry. State any required standard edition or actual product assessment document separately; no standard equivalence is inferred.
Common product questions
Is a nail anchor the same as a drop-in anchor?
No. The illustrated drive-pin family has an external head and projecting pin. An internally threaded drop-in anchor has a different receiving interface and setting system. Identify the exact construction.
Can the same installation values be used for all hammer-set anchors?
No. Hole, embedment, setting and acceptance requirements belong to the selected product and substrate. Family names or a picture do not supply those values.
Does this page confirm an approval or available size series?
No. Manufacturer references identify examples, not FastenerBridge approval, stock, brand authorization or qualified dimensions. Request the actual drawing and required product documents.
