Professional Applications & Engineering Value

This M4 x 0.7 x 25mm fully threaded screw delivers exceptional performance in mechanical assemblies, electronics, and industrial equipment where corrosion resistance and high tensile strength are critical. The 18-8 stainless steel construction, combined with a passivated finish, prevents rust and chemical degradation in humid or corrosive settings. Its coarse thread pitch and Class 6g thread fit reduce cross-threading risks and enable faster installation in metal or plastic components. The slotted cheese head offers broad contact for screwdrivers, minimizing cam-out during high-torque applications. Ideal for securing panels, machinery parts, and structural frames, this fastener ensures long-term reliability under dynamic loads and environmental stress.
