304 Stainless Steel Solid Round Bars
Straight, unthreaded round bars for small machined components, fabricated hardware and general workshop material requirements. The supplied product reference identifies 304 stainless steel, while the photographs show bright cylindrical surfaces and plain ends. Send the required diameter, length and quantity to obtain a specification-based quotation.
Product Specifications
| Item | Selection and ordering information |
|---|---|
| Product form | Solid round bar / straight round rod; unthreaded cylindrical profile. |
| Material | 304 stainless steel according to the supplied product reference. Confirm the applicable material standard and any material-report requirement with the quotation. |
| Reference diameters | 3, 4, 5, 6, 7, 8, 9 and 10 mm are listed in the reference. Confirm availability and diameter tolerance for each requested size. |
| Length | 1,000 mm appears in the reference options. State the required supplied length and length tolerance; other lengths require quotation review. |
| Surface | Bright metallic appearance as photographed. Specify a surface roughness or cosmetic acceptance requirement if needed; no numerical finish value is established by the photographs. |
| Ends | Plain ends shown. Specify whether cut ends, deburring, a chamfer or further end machining is required. |
| Straightness and fit | Confirm against the application or drawing. No precision shaft fit, straightness class or hardness rating is supplied in the reference. |
| Quantity and packing | State pieces per diameter and length, total quantity, destination and any surface-protection or bundle-label requirements. |
Choose the Bar for the Finished Part
A nominal diameter alone does not define the fit of a finished pin, shaft or spacer. Where a bar will be machined, include the finished-part drawing and any required machining allowance. For a close sliding or bearing fit, specify the working diameter, tolerance, surface roughness, straightness and material condition instead of relying on the pictured finish.
The images do not establish whether the material is precision ground, cold drawn or supplied in a particular heat-treatment condition. These requirements should be agreed before ordering. Also describe exposure to moisture, cleaning chemicals or other corrosive media so that the specified material can be reviewed for the intended use.
Typical Enquiries
- Bar blanks for turned pins, spacers and other small cylindrical parts.
- Straight rods for fabricated brackets, retainers and workshop assemblies.
- Material for prototype hardware and drawing-based machining projects.
- Rod stock for subsequent bending, where the required bend geometry and material condition are confirmed.
For shaped rod components rather than straight stock, see our stainless steel bright round bar bending product page.
Inspection Requirements
Define the checks needed for your order: material identification, diameter measurements, supplied length, straightness, end condition and visible surface defects. If traceability, a material report or a specific sampling plan is required, include it in the enquiry so availability and scope can be confirmed. See our quality control overview for the broader inspection approach.
Request a Round Bar Quote
Please send the following to help us review the requirement:
- Material grade and applicable specification.
- Bar diameter, supplied length and tolerance for each size.
- Quantity in pieces, with a size-by-size breakdown.
- Surface, straightness and end-condition requirements.
- Any subsequent machining or bending drawing, inspection documents, packing requirements and delivery destination.
Send your round bar sizes and quantity for a quotation. The listed reference sizes are not a live inventory or fixed-price schedule.
Frequently Asked Questions
Is this round bar a hollow tube?
No. This product is identified as solid round bar in the supplied reference. If you need tube, specify both outside diameter and wall thickness as a separate requirement.
Can I order a different diameter or length?
Send the size and quantity for review. The reference lists 3–10 mm diameters and shows 1,000 mm length options; other sizes, cutting and end preparation must be confirmed in the quotation.
Can it be used directly as a precision guide shaft?
Do not assume a precision guide-shaft specification from this listing. Confirm diameter fit, straightness, roughness, hardness and compatibility with the mating component before selecting material for that purpose.
