Professional Applications & Engineering Value

These 410 stainless steel tapping screws are specifically engineered to address common challenges in plastic assembly applications. The thread cutting design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The 18 TPI thread pitch provides optimal material engagement in plastic substrates, preventing stripping while maintaining structural integrity. The Phillips No. 2 drive system ensures reliable torque transmission during installation, while the pan head design offers a low-profile finish suitable for various industrial applications. These fully threaded screws with blunt tip configuration provide consistent performance in plastic components where vibration resistance and long-term reliability are critical requirements.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.164" thread diameter and 1-1/2" length, these thread cutting screws maintain consistent Class 2A thread tolerances. The Type 25/BT tapping screw configuration ensures proper thread formation in plastic materials when used with recommended No. 26 drill bits. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and market accessibility for industrial applications requiring certified industrial fasteners.
