JACK SCREW JSI-M Product Overview
JSI-M16 / JSX-M16 is a male-male metric jack screw adjuster with M16×2.00 threads. Thread length = 48 mm, hex size = 20 mm across flats, total length = 109 mm, hex height = 10 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-M16. Chromoly: JSX-M16. Special metric thread combinations available in volume. Inch equivalent is the JSI series.

JACK SCREW JSI-M Frequently Asked Questions
What is a JSI-M jack screw used for?
A JSI-M jack screw is a male-male metric adjuster used to fine-tune length or preload in linkage and threaded control assemblies.
What materials are available in this series?
Standard materials include carbon steel with zinc plating and chromoly steel for heavier-duty fabrication requirements.
How do I choose the right thread size?
Start with the required metric thread size, then confirm thread length, total length, hex size, and hex height for the assembly.
Are left-hand versions available?
This metric series is presented with standard metric thread patterns; review your assembly requirement with SYZ for project-specific supply needs.
What dimensions matter most for fitment?
Thread size, thread length, total length, and the wrench hex dimensions are the primary fitment points for jack screw selection.
Can SYZ make special sizes?
Yes. Special sizes are available in production volume for OEM or repeat fabrication programs.
