Stock versus finished bore
A tube-stock inside diameter is not automatically a precision locating bore; mark any fit requiring machining.
Short stainless steel tube sections used as customer-defined sleeves, stand-offs or spacers. Length, end condition and the fit to a mating shaft or fastener determine whether cutting alone is sufficient.

The dimensions below help us review tube sleeves & spacers. State units and critical tolerances on the original drawing. The illustration explains the type of geometry; it does not define a standard size.
| Inside and outside diameter | Define the mating fit and tube wall section. |
|---|---|
| Spacer length | State finished length and its functional tolerance. |
| End condition | Specify square ends, chamfers or machined faces. |
| Locating features | Show any cross holes or wall slots. |
| Material & quantity | Give the exact metal grade, standard, temper or condition, quantity per revision and planned repeat orders. |
| Units & tolerances | Use mm or inches consistently. Mark the dimensions that control fit and the inspection datum. |
Thickness range, minimum features, tolerances, finish availability and delivery date are reviewed for your actual part. No catalog dimension or blanket machining tolerance is implied.
Tube section, axial feature locations and the orientation of holes, slots and shaped ends.
A tube-stock inside diameter is not automatically a precision locating bore; mark any fit requiring machining.
For a spacer between mounting faces, define whether end parallelism and surface condition are critical.
Grade, environment and visible-face requirements are separate specification choices. Include them before quotation so the material and process route can be reviewed together.
Stainless steel options include 304, 304L, 316, 316L, 430 and duplex 2205. Carbon steel, galvanized steel, aluminium, copper and brass can also be discussed for your drawing. State the exact grade and applicable material standard.
Read the grade selection reference for general material context. Availability, product form and suitability are confirmed for the project. Explore all six material families.
Identify a mill finish, brushed appearance or another specified finish; include the visible face, grain direction and any surface-roughness requirement.
Specify edge deburring, protective-film handling and packing if they affect the delivered part. Read the finish terminology guide.
Material options are reviewed against your drawing, grade, thickness and finishing needs. Stainless steel remains our core focus; sourcing and the manufacturing route are confirmed during quotation.

Inspect length and end condition, with any precision bore or fit requirements checked after the agreed machining operations.
Provide the inspection datum, critical dimensions and any requested records with the inquiry. A model preview supports communication; the approved engineering drawing remains the manufacturing reference.
Quality & material requirementsProvide the required diameter and fit. A precision bore may need CNC machining rather than relying on the tube stock alone.
Send your tube sleeves & spacers drawing, grade, thickness or tube section, quantity, finish and critical dimensions. A clear PDF or image is accepted for review; a DXF supports flat cutting contours.
Include prototype quantity and expected repeat quantity in the inquiry. Batch size, process route and lead time are confirmed after the drawing and specification review.
Send the file and procurement requirements. No customer account is needed.
