DIN 103 · Tr thread
DIN 103 identifies the trapezoidal thread; the outer form and table dimensions belong to the stated technical selection. Tr 10 × 3 is excluded because the source flags its pitch as outside the DIN 103 series.

Tr threads are not interchangeable with M metric threads. Specify hand, clearance, lubrication and application. The documented steel selection is for manual adjustment or retention: do not automatically extend it to continuous-motion drives. Steel-on-steel pairing requires assessment of galling risk.
Table dimensions refer to the stated execution. DIN/UNI, polymer and special variants require verification of their own dimensions; they do not automatically inherit reference geometry, weight or performance.
Materials, classes, finishes and treatments
Other materials, property classes and finishes available on request.
State the required material, property class and finish in your enquiry. The configuration is defined and confirmed in the quotation.
Executions are distinguished by reference, material, class and finish. DIN, ISO and UNI references do not imply dimensional equivalence or availability of every size in each material. Supply and batch documents require quotation confirmation.
For this special execution, body material, any insert, class and treatment must be specified separately. Variants of geometrically similar products are not assigned automatically.
