Professional Applications & Engineering Value

These No. 6 x 1/2" zinc-plated steel TRS tapping screws are specifically engineered for plastic fastening applications where traditional threading methods prove inadequate. The thread forming design with tri-lobe shank cross-section displaces plastic material without cutting, creating stronger threads that resist stripping and back-out under vibration. The zinc-plated steel construction provides essential corrosion protection while maintaining the necessary strength for durable assemblies. The Phillips drive system ensures consistent torque transfer during installation, reducing the risk of driver slippage that can damage both the fastener and the plastic substrate. These features combine to solve common industrial challenges including material cracking, thread failure, and corrosion-induced fastener degradation in plastic component assembly across automotive, electronics, and consumer goods manufacturing.

Specification Summary & Compliance

These thread forming screws feature a No. 6 size with 0.138" thread diameter and 1/2" length, delivering precise dimensional accuracy for consistent performance. The TRS (Thread Rolling Screw) design with 19 threads per inch ensures proper thread engagement in plastic materials. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, meeting current environmental and safety standards for industrial applications. The standardized Phillips No. 2 drive and recommended 1/8" drill bit size facilitate proper installation according to industry best practices.
