JFK precision shimming systems
Precise dimensional control for every mechanical assembly
Precision metal shims in brass, steel, and stainless steel.
JFK precision shimming systems include precision metal shims, also known as “Carta Spagna,” as well as calibrated strips and precision strips made of brass, steel, or stainless steel. These components provide an effective and cost-efficient solution for optimizing the entire production process, allowing fixtures, tools, and dies to be fine-tuned while ensuring precision and efficiency in leveling operations and tolerance adjustment.
Easy to insert and remove, they are highly versatile and able to meet a wide range of requirements across many industrial sectors. Completing the range are self-adhesive metal shims, offering even greater simplicity and speed of use.

Precision metal shims: function and selection parameters
Precision metal shims are calibrated strips and precision shims used for dimensional adjustment of fixtures, dies, and tools, as well as for leveling and tolerance adjustment in mechanical assemblies. The choice of the right material depends on the expected mechanical load, the required corrosion resistance based on the operating environment, and the preferred fastening method, either mechanical or self-adhesive. JFK Group distributes and supplies the complete range of precision metal shims: every product is selected, inspected, and backed by technical support.
SELECTION GUIDE
Where are precision metal shims used?
JFK precision metal shims cover a wide range of applications across every sector of mechanical manufacturing. The choice of material depends on the type of machining operation, the applied load, and the operating environment in which the component will be used.
Where traditional mechanical fastening is not possible or practical, the self-adhesive version eliminates the need for screws or clips, further simplifying installation.
Solutions
Find the right solution for your application
01
Do you need to work the shims manually in the workshop?
Brass offers excellent ease of cutting and manual machining, making it the ideal choice for fixtures, dies, and tools where shims are adjusted directly in the workshop.
