3 Inch Metric Stem Caster Wheels with Side Brake

These 3 inch (approximately 75 mm) stem caster wheels are designed for equipment that uses metric threaded stem mounting and requires reliable braking control.

Featuring a side brake mechanism, this caster helps secure carts and equipment in place when stationary.

This product is specifically built for metric-standard applications, making it ideal for European and international equipment where imperial thread sizes are not compatible.

Metric Threaded Stem Options

This product is available in two metric threaded stem sizes:

• M10 × 1.5 × 30 mm
  Commonly used in light to medium-duty metric equipment and carts.
• M12 × 1.75 × 30 mm
  Suitable for heavier frames and equipment requiring a thicker stem diameter.

Both options share the same wheel diameter, braking mechanism, and load capacity. 

Only the thread size differs to ensure proper mounting compatibility.

Metric vs Imperial Threaded Stems

These casters use metric threaded stems (M10 / M12).

They are not compatible with imperial thread sizes such as 3/8"-16 or 1/2"-13, even though the wheel diameter is similar.
