• Excellent material displacement and vibration resistance thanks to the Tri-Lobe shank design that prevents loosening
• Complete thread engagement with fully threaded design ensuring maximum holding strength along the entire fastener length
• Streamlined assembly process with pre-determined No. 15 drill bit size for precise hole preparation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These No. 10 TRS tapping screws are specifically engineered for plastic applications where traditional fasteners often fail. The thread forming capability eliminates the need for tapping operations while preventing material stress cracks that compromise structural integrity. The Tri-Lobe shank design displaces plastic material during installation, creating a tight interference fit that resists vibration-induced loosening—critical for automotive trim, electronic enclosures, and consumer products. Made from zinc-plated steel, these screws provide excellent corrosion protection while maintaining the 14 threads per inch precision for consistent engagement. The Phillips drive ensures reliable installation with standard tools, reducing assembly time and improving production efficiency in high-volume manufacturing environments.

Specification Summary & Compliance

These thread forming screws feature a No. 10 diameter (0.19") with 14 threads per inch and 1-1/4" length, manufactured to precise dimensional standards. The TRS (Thread Rolling Screw) design with Tri-Lobe shank cross-section ensures proper thread formation in plastic materials. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they meet current environmental and safety standards for industrial use. The pan head style with Phillips No. 2 drive provides optimal clamping force distribution and drive reliability.
