Professional Applications & Engineering Value

This 000-120 thread flat head slotted screw in 18-8 stainless steel is engineered to address critical challenges in precision industries such as electronics, medical devices, and instrumentation. The fine thread spacing and Class 2A thread fit minimize the risk of cross-threading and provide reliable, repeatable fastening in thin materials or tightly toleranced components. The passivated finish enhances the innate corrosion resistance of stainless steel, making it ideal for environments exposed to moisture, chemicals, or sterilization processes. Its fully threaded body and standard flat head profile ensure easy installation with standard slotted drivers, while the 82° countersink sits flush to prevent snagging and maintain aerodynamic or aesthetic surfaces. By meeting ASME B18.11 specifications, this screw delivers consistent performance, reducing assembly errors and maintenance needs in high-stakes applications.
