M5 Hex Washer Head Thread Forming Screws For Metal Sheets Steel Fastener
Thread Forming Screw is designed for metal sheet ,it is made of high tensile strength carbon steel with zinc plated . the end of thread forming screw is formed triangle shape , this design ensures the screw is not backing out after installed , the angle of threads is 60 degrees or 55 degrees .
Thread forming screw needs a pre-drilling hole as it is machine thread style , screw will cut a hole with same threads as it is when thread forming screw is been rotating into hole ; Do not need a nut to secure the screw to avoid screw back out ; it is very convenient and cost-efficient .
We offer standard thread forming screw from M3 to M8 and we are available for customization
