Description Details

Restore the reliability of your Mazzer grinder's dosing system with the genuine Mazzer Screw for Doser Press Tamper (Part # M28251/S). This small yet critical OEM component is specifically designed to securely fasten the doser press tamper onto the doser body, ensuring consistent, repeatable operation in high-volume commercial environments. Replacing worn or lost hardware with this exact factory-spec screw prevents workflow interruptions and maintains precise dosing consistency. Key features include durable metal construction suitable for constant use, and a precision thread designed for a perfect fit on compatible Mazzer doser models.

The M28251/S screw is an essential maintenance item for preventing common doser issues and ensuring reliable tamping. Using this genuine replacement ensures your tamper remains rigidly in place, providing the firm connection necessary for proper coffee distribution after grinding.

It integrates seamlessly into the doser mechanism, promoting accurate dosing and reducing the risk of ground coffee spills.

Installation is straightforward, allowing baristas and technicians to quickly replace the screw and return the grinder to optimal service. The screw dimensions are typically M5 x 12 mm (confirm compatibility with your specific Mazzer model doser).
