Product Description

The Combination Lock Nut Set (M4 Locking Nut Kit) is a precision-engineered M4x30 Threaded Fastener Set designed for secure and vibration-resistant connections in demanding industrial applications. Each set includes 20 pre-assembled units, featuring M4x30 stainless steel bolts paired with locking nuts and integrated washers for tamper-proof assembly. Ideal for machinery manufacturing, automotive systems, and electronic enclosures, these fasteners operate effectively across -40°C to +120°C environments with corrosion-resistant coatings. The self-locking mechanism utilizes nylon-insert or deformed-thread technology to prevent loosening under dynamic loads. While offering exceptional shear strength (up to 8.8 grade) and IP67-rated weatherproofing, installation requires proper torque calibration. Compatible with DIN 985/6927 standards, this kit ensures reliable thread engagement for panel-mounted components, structural frameworks, and equipment requiring maintenance-free permanent fastening.
