Product Description

The Combination Lock Nut Sets M4 (20-pack) offer a robust solution for secure fastening in mechanical assemblies, automotive systems, and industrial equipment. This M4-12 locking nut kit includes 20 precision-engineered steel nuts with dual-thread locking technology, compatible with M4-12 to M4-20 threaded bolts. Featuring a nylon-insert locking mechanism, these nuts withstand vibrations and axial loads up to 8 Nm, operating reliably across -30°C to +120°C. The zinc-plated surface ensures corrosion resistance in harsh environments, while compact M4 sizing suits tight spaces in robotics, machinery, and electrical enclosures. The 20-pack M4 locking nuts come organized in a resealable anti-static tray, simplifying storage. Advantages include reusability and tool-free installation, though users must verify thread compatibility for optimal torque retention.
