| Field | Purchasing information |
|---|---|
| Standard / product type | DIN 931 or the stated edition of ISO 4014; hexagon-head bolt with an unthreaded shank and threaded end. Substitution is not assumed. |
| Thread and common size | State diameter, pitch, nominal length and threaded length. ISO 4014:2022 references coarse threads M1.6–M64; common enquiries often focus on M5–M36. Fine, left-hand and special threads require a complete specification or drawing. |
| Material | Carbon steel, alloy steel or stainless steel, selected for the required service environment and assembly. |
| Property class / stainless grade | Common RFQs include steel 4.8, 5.8, 8.8, 10.9 or 12.9 and stainless A2-70, A4-70 or A4-80. |
| Surface finish | Plain/oiled, zinc plated, black, hot-dip galvanized, zinc flake or another specified coating system. |

Technical notes
Open only the detail you need
Detailed standard and specification-control notes remain available without interrupting the main purchasing path.
Standard basis and equivalence
DIN 931 remains a common purchasing designation. ISO 4014:2022 is a current review reference for steel and stainless-steel hexagon head bolts with metric coarse threads M1.6–M64 and product grades A and B. XHT does not assume automatic interchangeability; the approved edition or drawing controls manufacture and inspection.
Common coarse-pitch reference
Common RFQs include M5×0.8, M6×1.0, M8×1.25, M10×1.5, M12×1.75, M14×2.0, M16×2.0, M18×2.5, M20×2.5, M22×2.5, M24×3.0, M27×3.0, M30×3.5, M33×3.5 and M36×4.0. Confirm every line item; fine, left-hand and special threads require a complete specification.
Mechanical requirements and documents
The product name does not define property class, stainless grade, test scope or certificate level. State the mechanical requirement, inspection plan and document package in the RFQ.
Specification and copyright control
Full copyrighted standard tables are not reproduced. Purchasing and acceptance follow the legally obtained governing standard, drawing revision and buyer-approved order specification.
