Product overview
Confirm the flange system before comparing quotations
A flange bolt combines the driving head and a wider bearing surface, but the product name alone does not define the flange diameter, under-head form, serration, thread length or mechanical requirement. Those fields are recorded before supplier comparison.
ISO 4162:2012 is a current small-series flange-bolt reference for M5 to M16. It is used here only as a review reference; XHT does not substitute it for a requested DIN 6921 edition or buyer drawing without approval.
What to include in your RFQ
- DIN 6921 edition, ISO basis or approved drawing
- Diameter, pitch, length and thread length
- Flange series and serrated or plain bearing face
- Material and property class or stainless grade
- Finish and coating performance requirement
- Quantity, packing, inspection and documentation

Verified technical note
Current ISO scope used for review
Official catalogue scope is summarized without reproducing proprietary dimensional tables.
| Reference / field | Verified scope used on this page | RFQ implication |
|---|---|---|
| ISO 4162:2012 | Hexagon bolts with flange, small series; M5 to M16; product grade A except the driving feature, which is product grade B | Confirm that the small-series ISO geometry is acceptable before treating it as the governing basis. |
| Mechanical classes | The ISO catalogue scope includes steel property classes 8.8 to 10.9 and stainless grade A2-70 | State the required class or grade and do not infer it from the product name. |
Specification control: DIN 6921 and ISO 4162 must not be treated as interchangeable unless the buyer approves the applicable geometry and edition. Full proprietary standard tables are not reproduced.
