ISO 14586 Hexalobular Countersunk Head Tapping Screws
ISO 14586 hexalobular countersunk head tapping screws ST2,9 to ST6,3 — the flush TORX sheet-metal screw, with the collected d2/k/TORX/(A)/t attribute rows per tapping thread.

Specifications
ISO 14586 is the flush member of the TORX tapping line: countersunk body, hexalobular socket, ST2,9 – ST6,3 tapping series. It answers the same production question as ISO 7050 (cross recessed countersunk) — flush finish, power-tool driving — but swaps the Phillips-class cross for the hexalobular socket, which carries more torque before cam-out and is the recess of choice in automotive and appliance panel work. The collected table mirrors the ISO 14585 pan member's compact set per tapping thread: head diameter d2 max. (6,3 → 12,6 mm — the countersunk head is the larger-diameter body vs the pan member's 5,6 → 12, because the cone needs the spread), head height k max. (1,7 → 3,15 — the low countersunk profile), TORX drive number (10 → 30), socket size (A) with the source's parentheses, and socket depth t max. (0,91 → 2,42 — shallower than the pan member's, the cone again). Drive rows align with the machine-thread hexalobular pages, so tooling transfers. The capture stops at these attribute rows: no length ladder or tapping-form rows — lengths, tapping form, material and finish are per RFQ.

Materials
- Material and finish specified per RFQ — state host sheet thickness (the cone needs it) and plating; case-hardened steel is the standard tapping body
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 14586 Hexalobular Countersunk Head Tapping 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
Hexalobular countersunk (ISO 14586) or cross recessed countersunk (ISO 7050) for a flush panel job?
Torque, tooling and tolerance — the heads themselves play the same flush role. The collected ladders make the comparison concrete: both are countersunk bodies over the same ST size span (this one starts at ST2,9), and both publish drive data per size — but the drive systems differ in what they tolerate. The hexalobular socket here (TORX 10 → 30, A 2,8 → 5,6) transfers more torque before cam-out and reams the recess less on repeated drives, which is why production panel lines prefer it; the cross recess on ISO 7050 is the universal fallback — a No. 2 Phillips bit is in every drawer. Two evidence-backed cautions: the hexalobular head's diameter ladder runs slightly larger (d2 max. 12,6 vs 12,4 at ST6,3) — the cone spread differs by a tenth, so pre-made csk tooling should be checked per the page's table rather than assumed interchangeable; and both captures stop at attribute rows (no length ladders), so lengths are RFQ lines on either. Material, tapping form and finish stay per RFQ.
