Product Description

The M4 Locking Nut Set, also known as the Combination Nut Set M4, is a precision-engineered fastening solution designed for high-vibration environments. Each Locking Nut M4*25-20 Sets package contains 20 pre-assembled units featuring M4 threading with a 25mm length, ensuring secure mechanical connections. Constructed from durable stainless steel with zinc plating, it operates within a temperature range of -20°C to +120°C and supports standard M4 bolts across automotive, aerospace, and industrial machinery applications. The dual-nut design provides vibration resistance without requiring additional tools, offering simplified installation and reliable torque retention. While optimized for medium-duty loads, its compact size (6mm outer diameter) may limit compatibility with oversized components. The set excels in assembly lines, robotics, and equipment requiring repeated disassembly.
