Professional Applications & Engineering Value

This M20x4 mm metric trapezoidal square nut is engineered to solve core challenges in linear motion systems, where precision, durability, and minimal maintenance are critical. The use of 360 brass provides inherent lubricity and resistance to seizing or galling, which is a common failure point in metal-on-metal threaded assemblies, thereby extending component life and reducing downtime. The trapezoidal thread form is specifically designed to handle high axial loads efficiently, making this nut ideal for applications like CNC machinery, positioning tables, and valve actuators. Its 7H thread fit guarantees precise engagement with lead screws, eliminating slop and ensuring accurate movement repeatability. The single start, right-hand thread with a 4 mm pitch offers a balanced combination of speed and force resolution, providing engineers with a reliable component for smooth and controlled motion transfer in automated equipment.

Specification Summary & Compliance

This nut conforms to metric trapezoidal thread standards with a size of M20 and a pitch of 4 mm. The thread is manufactured to a 7H thread fit tolerance, ensuring high precision and interchangeability. The component is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloy, confirming its adherence to stringent environmental and safety regulations for industrial use.
