Professional Applications & Engineering Value

These No. 12 x 1/2" zinc-plated steel TRS tapping screws are specifically engineered for plastic fastening applications where reliability and vibration resistance are critical. The thread forming technology creates strong, permanent threads in plastic materials without generating chips that could contaminate sensitive components. The Tri-Lobe shank design ensures superior resistance to loosening under vibration, making these Phillips drive screws ideal for automotive trim, electronic enclosures, and consumer products assembly. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for demanding industrial applications, offering engineers a dependable fastening solution that reduces assembly time and improves product longevity.

Specification Summary & Compliance

These TRS tapping screws feature a 0.216" thread diameter with 11 threads per inch and Class 2A thread tolerances for consistent performance. The fully threaded design and standard pan head profile ensure reliable fastening in plastic materials. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws meet international environmental standards for industrial use. The thread forming design eliminates the need for separate tapping operations, streamlining the assembly process while maintaining high fastening integrity in plastic components.
