Product Description

The Combination Lock Nut Set (M3 Combination Nut Kit) is a precision-engineered fastening solution designed for M3 threaded applications, featuring 20 sets of Locking Nut M3-25 Sets to ensure secure mechanical connections. Each set includes corrosion-resistant steel nuts with a zinc-plated finish, suitable for operating temperatures from -30°C to +120°C and ideal for automotive, electronics, and industrial machinery. The nuts provide vibration-resistant locking via a nylon-insert or serrated flange design, compatible with standard M3 bolts and offering a torque range of 0.5-1.2 Nm for reliable clamping. With a compact 25mm thread length and 5.5mm hex width, this kit excels in confined spaces while maintaining high tensile strength (8.8 grade). Advantages include reusability, rust prevention, and simplified assembly, though manual tightening may require specialized tools for torque accuracy. Widely used in robotics, CNC equipment, and aerospace subsystems for durable thread retention under dynamic loads.
