The Winco range of slot nuts
JW Winco offers a comprehensive range of T-slot nuts in various shapes and designs. A detailed overview of the different designs and their specific properties can be found here. This wide range ensures that the right solution is available for every application.
Advantages and areas of application
Slotted nuts are available in various sizes for different profiles.
Winco offers T-nuts that comply with the most common DIN standards.
It is important to distinguish between the width of the groove and the thread size.
The groove width refers to the width of the groove that is cut into a workpiece.
Slotted nuts made of steel and stainless steel
For some products, the material of the slot nut can be selected.
In addition to steel, we also offer slot nuts made of stainless steel.
Steel slot nuts are a robust and durable solution for connecting wood, metal, or plastic. They are easy to install, provide a strong, reliable connection, and are very cost-effective compared to stainless steel slot nuts.
Stainless steel slot nuts are more expensive than steel or aluminum slot nuts, but they are also less susceptible to corrosion.
Areas of application for T-slot nuts
Slot nuts, also known as T-slot nuts, are versatile fasteners that are used in various applications and industries.
Here are some typical areas of application:
- Mechanical engineering and machine tools:
- In milling machines, lathes, drilling machines, and other machine tools, slot nuts are used in T-slots to secure workpieces or fixtures.
- They enable flexible and precise positioning and fastening of clamping devices, clamping claws, and other tools on machine tables.
- Profile constructions:
- In aluminum profiles, such as those used in modular construction systems (e.g., Bosch-Rexroth, ITEM), T-slot nuts are used to connect and fasten profiles and accessories.
- They are often used in industrial frame constructions, machine housings, workstations, and conveyor systems.
- Assembly systems:
- In various assembly systems, such as in the automotive industry or in the manufacture of electronic devices, slot nuts are used to adapt assembly fixtures flexibly and quickly.
- Photovoltaic and solar systems:
- T-nuts are used in the installation of solar panels on support systems, particularly in aluminum profile rails.
- They enable the panels to be fastened easily and securely.
- Trade fair and exhibition construction:
- In modular exhibition systems and trade fair constructions, slot nuts are used to fasten various elements such as stands, brackets, and panels.
- Automation technology:
- In automation technology systems and machines, slot nuts are used to fasten sensors, actuators, and other components to rail or profile structures.
The use of T-slot nuts offers the advantage of high flexibility and easy adjustability, which is valued in many industrial and craft applications.
