Professional Applications & Engineering Value

Our M4 x 25mm zinc-plated steel TRS tapping screws are engineered specifically for plastic assembly applications where traditional fastening methods often fail. The thread forming design creates permanent, high-strength threads in plastic materials without generating chips or debris that could compromise electronic components. The zinc-plated steel construction provides essential corrosion protection while maintaining the necessary strength for demanding industrial environments. With Phillips No. 2 drive compatibility, these screws offer reliable installation using standard tools, reducing assembly time and improving production efficiency. The fully threaded design ensures maximum engagement throughout the entire 25mm length, delivering superior pull-out resistance in plastic housings, enclosures, and structural components across automotive, electronics, and construction sectors.
