S-90434A111 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the advanced TRS thread forming design that creates strong, permanent threads without chipping or cracking
• Enhanced corrosion resistance provided by the zinc-plated steel construction, ensuring long-term reliability in various industrial environments
• Efficient installation and reduced cam-out with the Phillips No. 2 drive system, allowing for secure torque transfer and faster assembly times
• Optimal flush mounting achieved through the standard flat head profile with 82° countersink angle, creating clean, professional finishes
• Excellent material displacement and vibration resistance from the Tri-Lobe shank cross-section, preventing loosening under dynamic loads
• Full threading along the 1" length provides maximum thread engagement and holding strength throughout the entire fastener
• Environmental compliance assurance with RoHS 3 and REACH regulations, meeting international standards for industrial applications

Professional Applications & Engineering Value

These No. 6 x 1" zinc-plated steel TRS tapping screws are specifically engineered to address common fastening challenges in plastic assemblies. The thread forming technology eliminates the need for pre-tapped holes while preventing material stress cracks that often occur with traditional fastening methods. The Tri-Lobe shank design displaces plastic material during installation, creating superior resistance to vibration and pull-out forces. With the Phillips flat head configuration and 82° countersink angle, these screws provide flush mounting in plastic enclosures, electronic housings, and automotive plastic components. The combination of full threading and blunt tip ensures controlled penetration depth and maximum thread engagement, making them ideal for high-volume manufacturing environments where reliability and installation efficiency are critical.

Specification Summary & Compliance

This TRS type tapping screw features a 0.138" thread diameter with 19 threads per inch and 1" fully threaded length. The fastener maintains precise dimensional accuracy with standard flat head profile (0.262" head diameter, 0.083" head height) and No. 2 Phillips drive compatibility. Manufacturing complies with industry standards for thread forming screws in plastic applications, including proper countersink angle of 82° for optimal seating. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
