Product Detail
Product Introduction
Titanium dowel pins locate, align or retain mating components. A complete definition includes titanium grade and condition, nominal diameter, tolerance or fit, length, end form, chamfer or radius, surface finish, straightness, optional internal extraction thread and inspection method.
Product Specifications
| Product | Titanium Dowel Pins | Grade | Titanium Grade 2 or Grade 5 |
|---|---|---|---|
| Standard | ISO 8734, DIN 6325 or other dowel-pin references may define geometry and tolerances when expressly invoked, but their standard material requirements do not automatically establish titanium supply. The order must separately define titanium grade, condition, fit, surface and acceptance. | Size & Form | Diameter, tolerance or fit, length, chamfer/radius, optional extraction thread and drawing-defined datum |
| Tolerance | Precision diameter, roundness, straightness, length and end geometry according to drawing or invoked dimensional reference | Supply Condition | Ground, turned or finish-machined; cleaned, protected and lot identified |
| Inspection | Available controls include MTC review, micrometer diameter mapping, length, roundness, straightness, surface finish, end geometry, internal-thread gauging and heat or lot traceability. | Documents | MTC, heat/lot traceability and agreed inspection reports |

FAQ
Which fit should be specified for a titanium dowel pin?
The designer should define clearance, transition or interference fit from the hole tolerance, assembly method, service temperature and required removability.
Can titanium dowel pins include an extraction thread?
Yes. Provide the internal-thread designation, depth, entrance chamfer and gauging requirement on the approved drawing.
Is ISO 8734 enough to order a titanium pin?
No. The dimensional reference must be supplemented with titanium grade, condition, surface, testing and any deviations from the standard material requirement.
