Dimensions are nominal values from the governing standard. Confirm the tolerance class for your application before ordering.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Manufactured to ISO / DIN, Turnbuckle — ISO / DIN (Series 156) are rigging hardware supplied by Engineering Hardware. The dimensional data, materials and selection notes are summarized here.
What Are Turnbuckle — ISO / DIN (Series 156)?
Turnbuckle — ISO / DIN (Series 156) are rigging hardware defined by ISO / DIN. They are selected by thread size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
CAD Source Reference
This page is generated from an original native CAD part model (SolidWorks .SLDPRT) of the turnbuckle — iso / din (series 156) family maintained by our engineering team, covering 2 recorded size configurations. The technical drawing shown above is rebuilt parametrically from the dimensional table, so it always reflects the exact size and configuration you select. Native CAD files (STEP / SLDPRT) can be supplied with your quotation on request.
Materials & Finishes
Rigging items are supplied in galvanized or stainless steel and are specified by working load limit and the design factor applied to it, together with the finish appropriate to the environment. The rated capacity, not the material alone, is the governing figure.
Specification Guides
Each size, material and standard of Turnbuckle — ISO / DIN (Series 156) has its own reference page with the figures for that one configuration.

Custom manufacturing · Made to drawing
Need a turnbuckle outside the standard range?
Dimensions, material, finish and form are specified from the drawing — a rigging hardware outside the standard range is a variation on existing tooling rather than a new design. Made by hot forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
