Professional Applications & Engineering Value
These 410 stainless steel tapping screws with UNC coarse threading are engineered to solve critical fastening challenges in industrial applications. The thread cutting design (Type 23/T) creates precise mating threads in brass, cast iron, and sheet metal without requiring pre-tapped holes, significantly reducing assembly time and labor costs. The combination of 410 stainless steel material and coarse 10-24 thread pattern provides exceptional resistance to vibration loosening while maintaining structural integrity in high-stress environments. The Phillips No. 2 drive system ensures reliable installation with standard tools, making these self-tapping screws ideal for production lines where consistency and efficiency are paramount.
Specification Summary & Compliance
This 10-24 UNC coarse thread tapping screw features Class 2A thread tolerances and complies with standard UNC thread specifications. The screw requires a No. 17 drill bit (0.173" diameter) for proper installation in designated materials. Manufacturing follows industry standards for tapping screw applications, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
