Pressed indentations, separately specified threads
A swedged anchor rod is a straight round rod with a drawing-defined region of pressed indentations. The original manufacturer describes pressing that displaces material rather than machining it away. The projecting machine-thread region and the intended embedded indentation region are different features. This page identifies the form and enquiry inputs; it does not determine an engineered anchorage design.
Product forms and drawing identity
| Choice or field | What to identify |
|---|---|
| Threaded end and swedged region | A common arrangement has one projecting threaded end and an unthreaded indentation region toward the other end. State both regions from controlled datums. |
| Threaded ends and swedged middle | A drawing-based variant may have threads at both ends with indentations in the middle. Thread length and swedge location still require separate definition. |
| Adjacent anchor forms | All-thread, headed rods, bent L/J rods and rods with a separate plate-end arrangement have different geometry. Do not substitute them on appearance alone. |
Define the indentation pattern, not just the name
The word swedged does not specify indentation depth, width, profile, spacing, orientation or the extent of the patterned zone. Alternating or spiral arrangements described in a manufacturer catalogue are examples, not a default for this enquiry. Use the approved drawing and inspection requirements; the AI illustration is deliberately generic and is not a pattern to manufacture from.
Keep projection, embedment and accessories controlled
Identify the complete rod length and where the thread, smooth and indentation regions start and end. Show the intended foundation/base-plate arrangement, projection and embedment on the project drawing. Specify nuts, washers and other separate components individually. Their presence, suitability and supply are not inferred from the rod image. Capacity and installation requirements belong to the responsible project design, not to this product-family selector.
Material standard identity is not geometry or conformity
The ASTM publisher catalogue identifies F1554-20 as active when checked on 10 October 2026. That catalogue identity does not by itself define this drawing's swedge geometry, establish product conformity or authorize substitution. State the required project edition and grade, material and finish, and the actual-part inspection and traceability documents. No licensed dimension tables, universal tolerances, load ratings or tightening torques are reproduced.
Specification fields
| Choice or field | What to identify |
|---|---|
| Rod and datums | Diameter, total length, reference datums and approved dimensional tolerances, all with units. |
| Mating thread | Thread system, diameter, pitch, hand, fit/class, threaded end or ends, usable length and runout. |
| Swedged region | Location and extent from a datum; indentation depth, width, profile, arrangement and spacing as controlled by the drawing. No default pattern is assumed. |
| Other end and assembly | End geometry, projection and embedment drawing; identify mating base/foundation and any separate nuts, washers or other components. |
| Material and finish | Required specification with edition, grade, finish, coated extent and any process restrictions; confirm through order documents. |
| Inspection and order | Drawing number/revision, dimensional checks, reports and traceability, quantity with pieces or sets, packing and destination. |
Common product questions
Is a swedged rod the same as all-thread or reinforcing bar?
No. Pressed indentations on an otherwise round rod are distinct from an external machine thread and from continuous reinforcing-bar ribs. Identify the required product and controlled drawing.
Does a standard number define the indentation pattern?
Do not infer a swedge pattern, embedment or anchorage capacity from the standard number. Specify the project edition, grade and drawing, and obtain the required actual-part documents.
Can the rod have threads at both ends?
A drawing may specify threaded ends with a swedged middle. State the location and extent of each thread and indentation region separately; it is not automatically interchangeable with a single-threaded-end rod.
