DIN 1479 Hex Turnbuckle Nuts
DIN 1479 hex turnbuckle nuts, M6 to M30 — the long unslotted hex nut that takes-up and locks turnbuckle and tension-rod threads — with the collected per-size tables: pitch, d 1/d 2, nut length L, across flats s and the m/t dims.

Specifications
DIN 1479 is the elongated hex nut of take-up and tension assemblies: run on a threaded rod (a turnbuckle barrel, a tie-rod end, an adjusting screw), it acts as a locknut that jams against a standard nut or a component face to hold the setting. The extra length L — 30 mm at M6 up to 125 mm at M30 in the collected table — gives the rod generous thread engagement, which is what a tension joint needs: more engaged turns to spread the load and a longer bolt of thread to absorb setting adjustments without running out of thread. The collected tables cover M6 to M30 in two column groups with pitch P, d 1 and d 2, length L (nominal with max/min), across flats s and the m/t approximate dims. The source reproduces the small d 1 max/min pair (4.3/3.7) across every size including M16-M30 and prints d 2 as "/" at M6 — both quirks are kept verbatim in the tables and disclosed, so confirm the intended geometry at RFQ. Thread-fit class, materials and finishes are not printed by the collected specification and stay per RFQ.
| Standard | DIN 1479 — hex turnbuckle nuts (elongated lock/take-up nuts for threaded rod and tension assemblies) |
|---|---|
| Series | M6 – M30 (two source column groups) |
| Tabulated geometry | Per size: pitch P, d 1 (max/min, source repeats 4.3/3.7 across all sizes), d 2 ("/" at M6; 21–32 at M20–M30), length L (nominal/max/min, 30–125 mm), across flats s (max/min), m and t (≈) |
| Function | Jams against a mating nut or face to lock turnbuckle and tie-rod settings; long body adds thread engagement |

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 (DIN 1479 Hex Turnbuckle Nuts) 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 a DIN 1479 turnbuckle nut lock a setting?
By jamming, not by friction insert. Run the DIN 1479 nut up against the component or the primary nut and torque the two against each other: the counter-facing thread flanks wedge, and the pair will not back off under vibration the way a single nut can. The long DIN 1479 body matters in two ways — it puts enough engaged turns on the rod that the jamming load spreads over several threads instead of stripping the first one, and it gives the adjustment stroke room so the jam can be set without the nut running off the end of the thread. Read the collected table's L column against your rod thread length before ordering, and note the disclosed source quirks on d 1/d 2 (the small d 1 pair repeated across all sizes and the "/" at M6) — state the intended rod and mating nut at RFQ so the fit is confirmed.
What is the MOQ and lead time for this nut type?
The minimum order quantity is 10,000 pieces. Stock items ship in 3–7 days; non-stock items are confirmed at quotation. Common sizes in this nut type are widely stocked; confirm the exact schedule against quantity and size mix at quotation.
