ISO 14580 Hexalobular Socket Cheese Head Screws
ISO 14580 cheese head screws with hexalobular (TORX-style) socket, M2 to M10 — the flat-topped cylindrical head upgraded from a slot to a high-torque six-lobe drive — with the full collected 10-size table: head geometry, socket number and engagement depths.

Specifications
ISO 14580 keeps the cheese head of ISO 1207 — cylindrical, flat-topped, surface-seated — and swaps the slot for a hexalobular socket, the TORX-style six-lobe recess that transfers far more torque without cam-out. The result is a screw built for power-driven assembly of small parts: the deep straight-sided head houses a generous socket, and the six-lobe drive lets an automated spindle run to full seating torque without the driver skipping out and marring the flat top, which is why this head form has largely displaced the slotted cheese head in appliance and automotive small-part work. The collected table runs M2 to M10 and tabulates per size: head diameter d k and height k with max=nominal / min limits, the Socket No. (6 through 50, growing with the thread), the A driving dimension (Ref.) that pairs the screw to its bit, the engagement depths t max/min — the recess depth band that decides whether the driver bottoms or cam-outs — plus the a runout, r fillet and x thread-end lash limits. The countersunk counterpart is ISO 14581 on this site; the pan head version is ISO 14583. Materials, property classes and finishes are not printed by the collected specification and follow the drawing callout.

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 14580 Hexalobular Socket Cheese 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 do I match the driver bit to this screw — and what is the t band for?
Two columns pair the screw to its tooling. The Socket No. is the recess size — 10 at M3, 30 at M6, 50 at M10 — which selects the bit series; the A dimension is the driving cross-section (Ref.) that confirms the fit. The engagement depth t is printed as a max/min band rather than a single value because the recess is a formed feature: too shallow and the bit cam-outs under torque, too deep and it bottoms before the head seats, and the band is what production tooling must hold for both. When you change bit brands or move to automated driving, check the A dimension and the t band together — that pairing, not head diameter alone, is what keeps a hexalobular joint seating consistently.
What is the MOQ and lead time for these screws?
Minimum order quantity is 10,000 pieces per item. Stocked sizes ship in 3–7 days; non-stock diameters, lengths or finishes are quoted with a confirmed schedule. Common sizes in this designation are widely stocked — confirm the exact schedule against quantity and size mix at quotation.
