ISO 2010 Slotted Raised Countersunk Head Screws
ISO 2010 slotted raised countersunk (oval) head machine screws — M1 to M10, the crowned flush head for thin or finished panels, with the collected geometry rows and the full weight ladder M1–M10 × l 2–60.

Specifications
ISO 2010 is the oval-head member of the slotted countersunk pair: like ISO 2009 it seats in a 90° countersink, but its raised face adds a shallow crown above flush — no sharp edge to catch, a slightly deeper head for the slot, and a deliberately "finished" look on instrument panels and switchgear. The collected data covers M1 through M10 with the full geometry ladder (including the crown parameters f approx. and rf approx. that the flat ISO 2009 page does not carry) and a complete kg/1000 weight matrix for lengths 2 to 60. Choose it over the flat version when the panel is thin enough that a flush head would sit proud anyway, or when the edge profile matters; choose ISO 2009 when true flush is required. One genuine anomaly is flagged rather than smoothed: at M5–M10 the source prints crown heights f larger than the total head heights k, which breaks the small-size progression — if the crown profile is dimension-critical, confirm per RFQ. Property class and finish are not tabulated by the collected specification — per RFQ.

- Row 11 ((18)): l = (18), M5 cell prints ",2,97" with a stray leading comma in the source. Carried verbatim, not normalized.
- Row 15 ((28)): l = (28): the source prints an extra stray-comma cell ahead of the M3 column (row shifted here by one during transcription; the value sequence 1,41 / 1,97 / 2,61 / 4,11 / 6,19 / 11,8 / 19,7 aligns M3 - M10). Carried verbatim, not normalized.
Materials
- Property class and finish specified per RFQ — oval heads are common on visible panels: 4.8 steel with bright or coated finish, brass, stainless; state the panel and look 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 2010 Slotted Raised Countersunk Head Screws) 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
Raised (ISO 2010) or flat (ISO 2009) countersunk head — what actually differs in the joint?
Flush versus crowned seating on the same 90° cone. Both pages share head diameters (7,5 mm at M4) and slot gauges, so they are near-drop-in alternatives at the countersink; the difference sits above flush. The flat ISO 2009 head finishes level with the panel — required when something slides over the face. The raised head adds the f/rf crown: the collected table shows f approx. 1 mm at M4 rising to 5 mm at M10, which leaves the slot deeper in proportion (better driver engagement on a soft material) and the visible profile rounded instead of edged — the classic choice on instrument fascias, switch plates and furniture hardware. It also tolerates a panel too thin to swallow a full flat head. One caution comes straight off the source, flagged on the table: at M5–M10 the crown rows print larger than the total-height rows, so a dimension-critical crown goes per RFQ, not off the cell. Class and finish stay per RFQ on both pages.
