Why Choose an M2 x 16mm Thumbwheel?

The extended 16mm threaded stud provides increased fastening depth and maximum thread engagement within this size range. This makes it particularly suitable for thicker materials, recessed mounting points and assemblies where additional adjustment travel is required.

The knurled thumbwheel design allows quick, precise and repeatable manual adjustment, helping to improve usability while reducing installation and maintenance time.

Benefits of A2 Stainless Steel

A2 stainless steel, also known as grade 304 stainless steel, is widely used throughout manufacturing and engineering industries due to its excellent resistance to rust, moisture and general environmental exposure.

The material offers a strong balance of durability, corrosion resistance and aesthetic appearance, making it suitable for both industrial and hygienic applications. Its non-magnetic properties and ease of maintenance further enhance its versatility across a broad range of operating environments.

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.
