A buyer searching for Bolt Metal is usually trying to stop a bad substitute. A metal product is specified by alloy, temper or grade, dimensions, and the certificate. The notes below are selection criteria for a Bolt Metal. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Bolt Metal
A metal product is specified by alloy, temper or grade, dimensions, and the certificate. For a Bolt Metal, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Bolt Metal is easy to confuse with Elbow. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Bolt Metal |
|---|---|
| Dimensions | Thickness, width, length, and tolerance. |
| Surface | Mill finish, coated, or a stated roughness. |
| Certificate | A mill certificate of the type the job requires, such as an EN 10204 type if that is what you need. |
| Quantity | Weight or pieces, and the bundle. |
| Alloy | The grade designation, not only steel or aluminum. |
| Temper or condition | Temper, hardness, or heat-treat condition. |
How to compare two offers
Lay both quotes for Bolt Metal on one sheet and line up dimensions, surface, and certificate. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Bolt Metal with a cheaper line that omitted dimensions.
Documents worth having before the deposit
Ask for the certificate type with the grade. The file should name Bolt Metal and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Ordering stainless without the alloy.
- Leaving temper off a sheet that will be formed.
- Accepting a trader’s stamp in place of a mill certificate.
On a Bolt Metal, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Bolt Metal — State alloy, temper, dimensions, surface, and certificate type.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like explosion-proof / ATEX belong
Searches often add a constraint to Bolt Metal: explosion-proof / ATEX, or automotive grade. Keep those on this page. ATEX or IECEx is a certificate for a zone, a gas or dust group, and a temperature class. An IP rating does not grant it. Skip the mark if the site is not hazardous. Automotive grade is a temperature, vibration, and documentation claim. Ask which AEC or customer spec is actually met, and for which part number. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Bolt Metal include?
State alloy, temper, dimensions, surface, and certificate type.
Is a cheaper Bolt Metal the same part?
Only if dimensions, surface, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Bolt Metal they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
