related-product-metricJSI-M6 / JSX-M6 is a male-male metric jack screw adjuster with M6×1.00 threads. Thread length = 18 mm, hex size = 10 mm across flats, total length = 45 mm, hex height = 4 mm.
The JSI-M (carbon steel, zinc plated) and JSX-M (chromoly steel) metric jack screws thread into metric rod end bodies at both ends, with a central hex for rotation. One end is right-hand; the other left-hand — rotating the hex adjusts overall length. Used in metric linkage assemblies, European machine controls, and any metric-threaded push-pull rod requiring fine length adjustment.
Carbon steel: JSI-M6. Chromoly: JSX-M6. Special metric thread combinations available in volume. Inch equivalent is the JSI series.

The JSI-M6/JSX-M6 is a male-male metric jack screw adjuster with M6×1.00 threads, built to thread into metric rod end bodies at both ends so a linkage rod's overall length can be fine-tuned. It's used in metric linkage assemblies, European machine controls, and any metric-threaded push-pull rod that needs adjustable length.
One end of the M6 thread is right-hand and the other is left-hand, so rotating the central hex draws both mating rod ends together or apart without unthreading either side — the same turnbuckle-style principle used on RH/LH rod end pairs.
Thread length is 18 mm per side, the center hex measures 10 mm across flats with a hex height of 4 mm, and total assembled length is 45 mm — confirm these against your rod end thread engagement and available install space.
JSI-M6 is made from carbon steel with a zinc-plated finish, while JSX-M6 is the chromoly steel version of the same M6×1.00 jack screw — choose JSI-M6 for standard-duty linkage tuning or JSX-M6 where the higher strength of chromoly is needed.
Yes. The JSI-M6/JSX-M6 is the metric version of this jack screw adjuster; the inch equivalent is covered under the JSI series with UNF/UNC threads — confirm which thread system your rod end bodies use before ordering.
Yes. Special metric thread combinations are available in volume — provide your target thread sizes on each end and quantity when requesting a quote.
