ISO 7436 Slotted Set Screws, Cup Point
ISO 7436 slotted set screws with cup point d 1,4 to 6 (M3 – M10 length ladder) — the screwdriver-driven anti-rotation point, with the collected n/t rows and the trade-size length matrix.

Specifications
The cup point is the bite of the set-screw world: a shallow ring edge that digs into the mating surface and resists rotation with far more grip than a flat point of the same size — the classic slotted choice for securing small gears, pulleys and settings rings against slip. The collected page gives the cup/slot geometry per diameter (the size run 1,4 / 2 / 2,5 / 3 / 5 / 6 is the source's own and skips d 4 — flagged verbatim) with slot width n (0,4 → 1,6) and slot depth t min. (0,8 → 2,4), then a length matrix by thread (M3 – M10, l 3 – 40) marked "+" where the source offers the length as a trade size. Thread labels on the matrix run M3 to M10 while the geometry columns are plain diameters — both carried as printed. Property class and finish are not tabulated — per RFQ.
| Standard | ISO 7436 — slotted set screws with cup point (driver-driven anti-slip point) |
|---|---|
| Size range | d 1,4 / 2 / 2,5 / 3 / 5 / 6 geometry columns (d 4 skipped in the source, flagged); length matrix M3 – M10, l 3 – 40 |

| Availability | "+" trade-size marks per length/thread pair, the source's own marker kept verbatim |
| Flagged verbatim | size run skips d 4; geometry columns print diameters while the length matrix prints thread labels |

Materials
- Property class and finish specified per RFQ — cup-point set screws commonly run case-hardened steel; state the mating shaft material and hardness (the cup ring bites harder stock deeper) and any stainless need at quotation
Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (ISO 7436 Slotted Set Screws, Cup Point) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 10,000 pieces. Stock items run 3–7 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
The size ladder on this page skips d 4 — which size do I use there?
The collected ISO 7436 page genuinely has no d 4 column: its geometry run prints 1,4 / 2 / 2,5 / 3 / 5 / 6 (flagged verbatim rather than interpolated), so between the d 3 and d 5 geometry sets the practical route is to order by thread — the length matrix covers M3 to M10 and a d 4 nominal screw corresponds to the M4 column's envelope. Do not average the neighbour columns; cup depth and slot width step with the stock diameter. If your drawing calls a specific d 4 cup-point screw, confirm per RFQ and we will quote against the standard rather than this capture. Also note the two labelling systems on one page: geometry columns are plain diameters, the length matrix uses thread labels — match your drawing's convention when ordering. Class and finish per RFQ; the "+" marks in the matrix are the source's own trade-size availability, kept as printed.
