ISO 14584 Hexalobular Socket Raised Countersunk Head Screws
ISO 14584 hexalobular (TORX) socket raised countersunk head screws M2 to M10 — the machine-thread TORX countersunk with a raised crown, with the collected a/b/dk/k/TORX/A/t attribute rows.

Specifications
ISO 14584 is the machine-thread counterpart of the x117 hexalobular line: TORX drive, raised countersunk head, metric thread M2 to M10. The raised countersunk body gives it the flush member's centered cone seating plus a shallow crown that keeps the bit engaged and spreads driving load — the choice for jigs, fixtures and machine builds where the screw sits proud enough to matter and flush enough not to foul. The collected table is the compact machine-thread set: thread-end allowance a max. (0,8 → 3), minimum thread length b min. (25 mm on the small sizes, 38 from M4 — the "get full clamp before the thread bottoms" row), head diameter dk max. (4,4 → 20), head height k max. (1,2 → 5), the TORX drive number (6 → 50), the hexalobular socket size A (1,75 → 8,95) and socket depth t max. (0,77 → 3,81). What the table does not carry: a length ladder, property class or finish — lengths and class are per RFQ (the collected page stops at the attribute rows). Drive discipline is the hexalobular family's: TORX size from the table (e.g. TORX 25 at M5), not from guesswork by thread — the A/t rows are the socket's machined envelope. Material and finish per RFQ.

Materials
- Material and finish specified per RFQ — state thread engagement length and duty; machine-thread TORX bodies are commonly property-class 8.8+ steel or stainless, confirm 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 14584 Hexalobular Socket 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
How does ISO 14584 differ from the x117 hexalobular pages (ISO 14579/14582) already in this catalog?
Thread system and head shape — and the collected evidence says so on its face. ISO 14579/14582 in this catalog are machine-thread pan and countersunk hexalobular screws; ISO 14584 is the raised-countersunk member of that machine-thread family, and its collected rows differ in kind: b min. (minimum thread length, the machine-thread clamping row — 25/38 across M2–M10) appears only on the machine-thread standards, while the tapping siblings carry ST thread rows and tapping-specific allowances instead. Within the machine trio the head is the choice: pan (14579) for bearing surface without prep, countersunk (14582) for flush, raised countersunk (14584) for flush-plus-crown. The drive system is common — the TORX/A/t rows here (TORX 25, A 4,5 at M5) are directly comparable to the 14579 page's, so one TORX driver set covers the family. This page's collected table stops at the attribute rows — no length ladder — so lengths, class, material and finish are all RFQ lines; the x117 pages carry the deeper ladders where their sources tabulated them.
