Drop Forged Turnbuckles

A turnbuckle is a threaded tensioning device: turning the body draws the two ends together or lets them apart, so a wire rope, chain or lashing can be tensioned to the exact length needed. The DIN 1478 and DIN 1480 types below are closed body, drop forged carbon steel.

How to select

How to select

  1. Match the thread size to the wire rope diameter: the two ends must close fully into the body, with the thread protruding far enough to engage the full length of the threaded end.
  2. Check the adjustable range. L5 in the table is the overall closed length; the open length is substantially longer, so confirm the installed space allows the adjustment range you need.
  3. DIN 1478 and DIN 1480 are tensioning devices. They are not rated for overhead lifting and must not be used to support a suspended load.

Applications

Wire rope tensioningGuy wires and mast staysFence and barrier tensioningShrink wrap and load restraintTunrigger and stage riggingHandrail and balustrade cables

Safety & use notes

  • Tensioning use only. Never use a DIN 1478 or DIN 1480 turnbuckle to support a load overhead.
  • Both ends are left-hand / right-hand threaded. Confirm the direction of adjustment before installation so the body can be opened for length and closed for tension.
  • Do not exceed the rated load, and do not use a turnbuckle that has been bent, had the thread galled, or shows any distortion.

  • Drop forged turnbuckle DIN 1478Closed body type to DIN 1478, drop forged carbon steel, sizes M6 to M48. Used purely for tensioning wire rope, guying and fencing.
  • Drop forged turnbuckle DIN 1480The heavier DIN 1480 pattern with a larger body section, for higher tension loads and more demanding guys.
Manufacturing

How it is made

  1. Bar or forging stock is cut to length and the body blank is formed — an open frame for DIN 1480, a closed tube for DIN 1478.
  2. End fittings are forged and then machined; the thread is cut or rolled to the specified form and gauged.
  3. The body and ends are assembled and the thread run is checked over the full adjustment range before the finish is applied.
  4. Surface treatment — hot-dip galvanising, electro-galvanising or self-colour — is applied, then the thread is re-checked so the ends still turn freely after coating.

What to check on receipt

  • Both end fittings turn freely through the full adjustment range without binding.
  • Thread form and engagement are adequate — with an open body you can see the engagement directly.
  • The body is not twisted or bent, and the ends are not cracked at the root of the thread.
  • Marking is present and legible; the size is the size you ordered.
FAQ

FAQ

What is the difference between DIN 1478 and DIN 1480?
DIN 1480 has a heavier body and higher load capacity at comparable lengths; DIN 1478 is the lighter pattern. Dimensions and weight per 100 pieces are listed separately for each standard above.
Can these turnbuckles be used for lifting?
No. Both standards are for tensioning only. If you need a device to support a load overhead, tell us and we will quote a rated lifting turnbuckle instead.
Can a turnbuckle be used for lifting?
No. Turnbuckles are tensioning devices. Every catalogue we checked states this without exception — they are for tensioning, bracing and adjustment, never for lifting. See the load note on each model page.
Do DIN 1480 and DIN 1478 specify a working load limit?
No. Both standards specify the dimensions and the thread form of the turnbuckle, not a working load limit. Load figures in suppliers' catalogues are each manufacturer's own declared values. As an indication, published figures for DIN 1480 eye-and-eye in carbon steel run from roughly 230 kg at M6 to about 9,300 kg at M36, with sources differing by 2–3%.
What is the difference between DIN 1480 and DIN 1478?
DIN 1480 is the open-body (jaw and eye) turnbuckle; DIN 1478 is the closed-body pattern. Both tighten by drawing two threaded ends together — one end has a right-hand thread and the other a left-hand thread, or the body itself rotates.
What sizes can you supply?
Our catalogue lists DIN 1480 in sizes from M6 up to M48 and DIN 1478 from M6 to M48, alongside commercial, Italian and US patterns. Tell us the standard, the thread size and the end fittings you need and we will confirm what we hold.

Load rating — what the standard does and does not say

DIN 1480 and DIN 1478 specify the dimensions and the thread form of the turnbuckle. They do not specify a working load limit. Load figures in suppliers' catalogues are each manufacturer's own declared values, not a standard figure.

To give you a sense of the range: published catalogues for DIN 1480 eye-and-eye turnbuckles in carbon steel list roughly 230 kg at M6 rising to about 9,300 kg at M36. Two independent sources differ by around 2–3% at the same size, which is why we quote a range rather than a single number.

The rated figure depends on the end fittings (eye, hook, jaw, stub end), the material and the heat treatment — so two turnbuckles of the same thread size can legitimately carry different ratings.

Caution:Turnbuckles are tensioning devices, not lifting devices. Every catalogue we checked states this without exception: turnbuckles must never be used for lifting. Use them for tensioning, bracing and adjustment only.

Sources: Eurocable (NL) DIN 1480 eye/eye and eye/hook listings; CLGR Industrial DIN 1480 stub end; Seriga Lifting DIN 1480; Deyuan Marine DIN 1480. Figures cross-checked across these four — the two clusters of values differ by 2–3%.
