• Secure fastening performance with 24 TPI fine threading that delivers excellent holding power in plastic materials
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered for plastic fastening applications where traditional fasteners often fail. The thread-forming technology eliminates the risk of plastic cracking or stress fractures by displacing material rather than removing it, creating stronger threads that won't strip under vibration or thermal cycling. The Tri-Lobe shank design provides exceptional resistance to back-out forces, making these Phillips drive screws ideal for automotive trim, electronic enclosures, and consumer products where reliable plastic-to-plastic or plastic-to-metal connections are critical. The blunt tip ensures proper alignment without damaging delicate plastic components during installation.

Specification Summary & Compliance

These No. 3 x 1/2" tapping screws feature precise 0.099" thread diameter with 24 threads per inch and standard Class 2A thread tolerances. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications with fully threaded configuration and pan head style measuring 0.193" diameter. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets. Recommended for use with No. 43 drill bits (0.089" diameter) for optimal performance in plastic materials.
