• Enhanced holding power with tri-lobe shank cross-section and full threading provides superior resistance to pull-out and vibration
• Clean installation with blunt tip and standard flat head profile allows for flush mounting with 82° countersink angles
• Reliable performance in plastic assemblies with optimized No. 6 size and 19 threads per inch for maximum engagement strength
• Regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for plastic fastening applications where traditional threaded fasteners often fail. The TRS thread forming design creates strong, permanent threads in plastic materials without generating chips or debris, eliminating contamination concerns in sensitive assemblies. The tri-lobe shank cross-section displaces material during installation, creating exceptional resistance to vibration loosening and pull-out forces. With T10 Torx drive technology, these screws deliver maximum torque transmission while preventing cam-out damage to both the fastener and installation tools. The standard flat head profile with 82° countersink angle ensures flush mounting in plastic components, making them ideal for electronics enclosures, automotive trim, and consumer products where aesthetic finish and structural integrity are equally important.

Specification Summary & Compliance

These No. 6 x 1-1/4" tapping screws feature a 0.138" thread diameter with 19 threads per inch and are manufactured to precise dimensional standards for consistent performance. The thread forming (TRS) design creates strong, permanent threads in plastic materials without pre-tapping. All fasteners are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for industrial applications. The zinc-plated steel construction provides corrosion resistance while maintaining the mechanical strength required for demanding plastic assembly operations.
