DIN 933:1987-09 is withdrawn. DIN 933 remains the enquiry designation on this page; where an ISO basis is requested, confirm ISO 4017:2022 and the required dimensions and thread details with the order. Catalogue references: DIN Media · ISO
Product overview
DIN 933 is still commonly used as an RFQ designation for fully threaded hex head fasteners. A useful quotation also needs the exact edition or approved drawing, thread size, nominal length, mechanical requirement, surface finish, quantity, packing and any inspection or document requirement.
For a current ISO basis, ISO’s official catalogue states that ISO 4017:2022 covers steel and stainless-steel hexagon head screws with metric coarse pitch threads from M1.6 to M64 and product grades A and B. XHT does not assume that a buyer’s DIN 933 request can be changed to another standard without approval.
Common ordering range
The options below cover common international RFQs. Availability, tolerances and compliance are confirmed size by size before quotation.
| Selection field | Common RFQ options | Quotation note |

| Common coarse pitch reference | M3×0.5 · M4×0.7 · 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 · M36×4.0 | Fine, left-hand and special threads can be supplied when defined by the RFQ or drawing. |
| Material and grade | Carbon or alloy steel: 4.8, 5.8, 8.8, 10.9, 12.9; stainless steel: A2-70, A4-70 or A4-80 | Mechanical requirements, test scope and certificates are confirmed before order. |
| Surface finish | Plain/oiled, zinc plated, hot-dip galvanized, black finish, zinc flake or specified coating system | State colour, coating thickness, corrosion requirement and thread-fit expectation. |
| Custom supply | Non-standard length, special thread, head marking, coating, packaging, drawing-based or sample-based production | Custom sizes are reviewed from drawings or samples. |
