Product type
JFK Precision Metal Shims (Carta Spagna)
Brass, steel and stainless steel
JFK precision metal shims, also known as Carta Spagna, are calibrated strips and precision shims made of brass, steel, or stainless steel. They provide an effective and cost-efficient solution for optimizing the entire production process: they allow 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. The latest addition to the JFK product range is self-adhesive metal shims, developed to meet customer needs through their simplicity and speed of use.

Three materials for every shimming requirement
The choice of material depends on the operating environment, the required mechanical strength, and the workability requirements of the shims. If you are unsure which material is right for you, the “Selection Guide” section at the bottom of this page can help you choose. Alternatively, contact us directly for technical support.
Steel shims
High mechanical strength · High hardnessFor applications involving higher loads or requiring greater mechanical strength. Suitable for positioning applications on machine tools and prismatic guides.
Stainless steel shims
For humid or chemically aggressive environments, or applications with high hygiene requirements. Suitable for the food, pharmaceutical, and chemical industries.
Self-adhesive metal shims
Quick installation · No mechanical fastenings · All materialsSelf-adhesive version available in all materials, eliminating the need for mechanical fastening. Simple and quick to use, even in hard-to-reach areas.
