ISO 7434 Slotted Set Screws, Cone Point
ISO 7434 slotted set screws with cone point, M1 to M12 — the small-screw end of the slotted set-screw line, with the slot n / cone dt / recess t grid plus a mass ladder marked with the source's "+" trade sizes.

Specifications
The cone point bites: unlike the flat point of ISO 4766 (already in this catalog), the coned end of a set screw digs into the opposing surface, which is what you want when the screw must positively locate a part that sees torsion — collar clamps on shafts, index stops, tooling plates — and at M1 to M12 this designation covers the instrument-and-fixture range where slotted drive still beats hex sockets (you can turn it with a plain blade, and the screw stays replaceable in the field). The collected grid runs thread P 0,25 → 1,75, cone-point diameter dt max 0,1 → 3 (dt min. is "-" across the line per the source — the point is formed to max), slot n 0,2 → 2 nominal, and the recess t 0,4 → 2,8 nominal; the lower band is the mass ladder, weight in kg per 1000 pieces across 20 nominal lengths l 2 → 60, with "+" marking the source's trade sizes. Quoting notes: dt max at M6 prints 1,5 against the 0,4/0,5/2 run of its neighbours — verbatim flagged, confirm that one cell per RFQ if your order lands on M6. Material, hardness and finish are not tabulated — per RFQ; lead time, MOQ and pricing: contact for confirmation.

- Row 5 (n): dt max. at M6 prints 1,5 against the 0,4 / 0,5 / 2 run at M5 / M6-neighbours (M4 0,4, M5 0,5, M8 2) — carried verbatim; confirm M6 cone diameter per RFQ.
- Row 10 (l): the mass band header "l | weight kg/1000pcs" then "nominal | min. | max. | (+ trade sizes)" is the source's own banding, carried verbatim.
Materials
- Material and finish specified per RFQ — small set screws commonly run hardened alloy or stainless; state the host material (the cone point mars it — use a flat point where marring matters) and the tightening tool (plain screwdriver blade width vs the n slot) 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 7434 Slotted Set Screws, Cone 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
Cone point (ISO 7434) vs cup point (ISO 7436) vs flat point (ISO 4766) — when does each win?
Point geometry decides how the set screw transfers load and what it does to the mating surface. The cone point (this page) penetrates: highest torque resistance against rotation, at the cost of marring the shaft or housing — the pick for permanent indexing, hard shafts, and joints where the mark is acceptable. The cup point (ISO 7436, also in this catalog) is the compromise: a shallow cup that bites like a punch but spreads the deformation, and it is the general-purpose default in most clamping work. The flat point (ISO 4766) contacts on a full plane: least marking, lowest rotation resistance — right against soft or finished surfaces, and for use as a plug or adjustment stop rather than a drive-catching clamp. Practically: match the designation your drawing prints; if the drawing says only "slotted set screw M4", pick by the function above and confirm the point form per RFQ. The mass ladders on the ISO 7434 and ISO 7435 pages let you price bulk orders before the confirmation step; "+" cells are trade sizes per the source legend.
