ISO 7435 Slotted Set Screws, Long Cone Point
ISO 7435 slotted set screws with long cone point, M1,6 to M12 — the sibling of ISO 7434 with the extended point (z rows) for deep-seated locating, with two verbatim source quirks flagged (n max 0,26 at M 8, t max 10,5 at M 3).
Last updated: 2026-11
Specifications
Where the ordinary cone point just marks, the long cone point reaches: ISO 7435's extended point (the z rows, 0,8 → 6 min / 1,05 → 6,3 max across M 1,6 → M 12) seats into a drilled recess or locates a part set back in a bore, keeping the clamping face of the screw shank clear of the component — useful in chuck and arbor work, and anywhere the point must engage before the shank does. The collected grid runs M 1,6 → M 12: thread P 0,35 → 1,75, point diameter dp 0,8 → 8,5 (max) / 0,55 → 8,14 (min), slot n 0,25 → 2 nominal, recess t 0,56 → 2,8 min, and the mass ladder across 20 nominal lengths l 2 → 60. Three verbatim quirks to note before quoting: the source titles the page "Slotted set screws and pins", but the tabulated columns are a slotted set-screw attribute set (dp/n/t/z) — the tension is disclosed rather than resolved; n max at M 8 prints 0,26 against the ,06 pattern; t max at M 3 prints 10,5 against the 1,05 step of its neighbours. All three are flagged in the table — confirm those cells per RFQ if your order lands on M 8 or M 3. Material, hardness and finish are not tabulated — per RFQ; lead time, MOQ and pricing: contact for confirmation.

- Row 6 (n): n max. at M 8 prints 0,26 against the ,06 pattern (0,31 / 0,46 / 0,56 / 0,66 / 0,86 / 1,06 / ...) — carried verbatim; confirm M 8 slot max per RFQ.
- Row 9 (t): t max. at M 3 prints 10,5 against the 1,05 step of its neighbours — carried verbatim; confirm M 3 recess depth per RFQ.
- Row 16 (3): source order quirk: the n rows print Nominal size / max. / min. (min. after max.), unlike the min./max. order elsewhere — carried in source order.
Materials
- Material and finish specified per RFQ — long-cone set screws commonly run hardened alloy steel; state the bore/recess the point must seat in (the z point length has to have somewhere to go) and whether the marked surface is acceptable 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

- 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 source calls this "Slotted set screws and pins" — is it a screw or a pin, and when is the long point worth specifying?
It is a set screw — the collected columns (dp point diameter, n slot, t recess depth, z point length over a length ladder with masses) are a set-screw attribute set, and the "and pins" in the source title is its wording, disclosed here rather than silently adopted. The designation itself is unambiguous. On when the long point wins over the ISO 7434 ordinary cone: specify the long cone when the point must engage a pre-drilled recess or reach past a shoulder — the z row is the extra point length that does that engaging (0,8 → 6 across the range, so the mating recess depth must be planned to match), while the shorter ISO 7434 point is the right choice for direct-into-surface indexing where there is no recess to seat in. Two cells on this page are verbatim-flagged in the table (n max 0,26 at M 8, t max 10,5 at M 3) because they break the numeric pattern of their rows; if your order lands on those sizes, confirm the printed values per RFQ before quoting the drawing. Sibling designations ISO 7434 and ISO 7436 are in this catalog with their own ladders.
