Professional Applications & Engineering Value
These 1/4" TRS thread forming screws are specifically engineered for plastic fastening applications where reliability and durability are critical. The zinc-plated steel construction provides essential corrosion protection in industrial environments, while the Torx Plus IP30 drive system delivers superior torque transmission without the slippage common with traditional drives. The Tri-Lobe shank design creates a secure interference fit in plastic materials, preventing rotation and maintaining clamp force over time. These thread forming screws eliminate the need for pre-tapped holes, streamlining assembly processes in plastic components for automotive, electronics, and consumer goods manufacturing. The fully threaded design ensures consistent engagement throughout the material thickness, making them ideal for demanding plastic assembly applications where vibration resistance is paramount.
Specification Summary & Compliance
These tapping screws feature a 1/4" thread diameter with 10 threads per inch and fully threaded configuration for maximum holding strength. The TRS (Thread Rolling Screw) design utilizes thread forming technology that creates strong, precise threads in plastic materials without generating chips. Manufactured to industry standards with right-hand thread direction and standard pan head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide.
