Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for plastic fastening applications where reliability and durability are paramount. The TRS thread forming technology creates strong, clean threads in plastic materials without generating chips, eliminating contamination risks in sensitive assemblies. The tri-lobe shank cross-section provides superior resistance to vibration loosening while distributing stress evenly throughout the plastic substrate. With a 1-3/4" length and No. 6 diameter, these screws offer optimal engagement depth for medium to thick plastic sections. The Phillips No. 2 drive ensures efficient installation with common industrial tools, making them ideal for high-volume manufacturing environments in automotive, electronics, and consumer goods assembly where consistent performance in plastic components is critical.

Specification Summary & Compliance

These No. 6 x 1-3/4" tapping screws feature a 0.138" thread diameter with 19 threads per inch and Class 2A thread tolerances for consistent performance. The TRS thread forming design follows industry-standard specifications for plastic fastening applications. Manufactured from zinc-plated steel with a pan head profile and blunt tip for controlled penetration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions.
