PART-SPECIFIC BUYING GUIDE

What to include in this section request.

Drawing and acceptance questions, not supplier specifications.

Fit and interfaces: Show the tube orientation and the location of holes relative to the assembly. Identify any inserted connectors and surfaces that must remain free of coating.
Finished-part scope: Ask how machining and finishing will be sequenced. A later hole or end cut may expose bare material; state whether that condition is acceptable.
Sample and acceptance: Approve a physical blue finish sample and the agreed hole-check method. A screen image does not set a repeatable color or gloss requirement.

START WITH THE MATING PART

Will the tube be visible on every face, and must machined edges match the blue exterior?

Hole locations; end condition; masked areas.

Attach the drawing revision, units, quantity and cut length. Undecided requirements can stay open.
