Ø25mm M2x12mm Stainless Thumbwheel to DIN653

This 25mm diameter thumbwheel is supplied with an M2 x 12mm male thread and manufactured from premium A2 stainless steel (304 grade) for excellent durability and corrosion resistance. The knurled outer surface provides a secure grip, allowing fast and accurate manual adjustment without the need for tools.

Manufactured to DIN 653 standards, this thumbwheel is ideal for applications requiring longer threaded engagement, making it particularly suitable for deeper mounting positions, thicker assemblies and specialist engineering projects where secure fastening and repeatable adjustment are essential.

Typical Applications

M2 x 12mm stainless steel thumbwheels are commonly used in:

• Industrial machinery and production equipment
• Instrumentation and calibration systems
• Control panels and electrical enclosures
• Laboratory and scientific equipment
• Food processing and hygienic environments
• Marine and outdoor installations
• OEM manufacturing projects
• Precision engineering assemblies

Why Choose an M2 x 12mm Thumbwheel?

The extended 12mm threaded stud provides increased fastening depth and greater thread engagement compared with shorter variants. This makes it an excellent choice where components must pass through thicker materials or where additional adjustment range is required.

Combined with a comfortable knurled grip, the thumbwheel allows quick manual operation while maintaining secure and reliable fastening performance.

Benefits of A2 Stainless Steel

A2 stainless steel, commonly known as grade 304 stainless steel, is widely used throughout engineering and manufacturing due to its excellent balance of corrosion resistance, strength and durability. It performs well in humid, washdown and general industrial environments, helping to minimise maintenance while extending product life.

Its hygienic properties also make it suitable for food processing, laboratory equipment and clean working environments where resistance to rust and contamination is important.

Alternative Sizes Available

We offer a wide range of male threaded stainless steel thumbwheels with thread sizes from M2 to M10, available with both male and female thread options. If stainless steel is not required, our standard handwheel and thumbwheel ranges may provide a more economical solution.
