Shafts with Flats

The photograph shows shafts with clearly visible flat sections at their ends. The image helps illustrate this form, while the buyer's drawing defines the part to manufacture. A similar outline does not establish an interchangeable shaft. We review the flat sections together with the round diameters, length and end features before confirming the quotation requirements.

Show where each flat begins and ends, its required depth or remaining section, and its position around the shaft. When flats appear at more than one location, identify how they align with each other and with any other feature. Provide the relevant drawing reference so the intended orientation can be understood without interpreting the camera angle of a sample photograph.

Specify mating diameters and any shoulders, grooves or end details on the same drawing. State the material grade and condition, edge requirements and any treatment. Our custom turned-part work can include milling as an additional operation, with feasibility reviewed for the complete geometry. The photograph does not identify a material, a fit or the load that a finished assembly can carry.

Send the current revision with the quantity and required date, and mark any orientation or edge detail that still needs agreement. The shaft drawing checklist and RFQ checklist explain the information to include. View the precision shaft family for other forms, or send your drawing enquiry.
