S-90434A169 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding environments
• Enhanced installation reliability through Phillips No. 2 drive design, reducing cam-out and improving torque transfer
• Maximum holding power in plastic with Tri-Lobe shank cross-section that displaces material to create secure, vibration-resistant threads
• Reduced assembly steps with thread forming technology that eliminates the need for pre-tapped holes in plastic components
• Clean flush mounting thanks to standard 82° flat head profile that sits perfectly countersunk in plastic surfaces
• Full-length fastening capability with completely threaded shank for consistent grip along the entire engagement length
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

Engineered specifically for plastic fastening applications, these TRS type tapping screws solve critical challenges in plastic assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength needed for durable connections. The innovative Tri-Lobe shank design and thread forming technology work synergistically to compress plastic material rather than cutting it, creating superior pull-out resistance and eliminating problematic chips. This makes them ideal for plastic components in electrical enclosures, automotive trim, consumer products, and industrial equipment where vibration resistance and long-term reliability are paramount. The Phillips flat head configuration ensures flush installation with standard 82° countersinks, delivering both aesthetic appeal and functional performance.

Specification Summary & Compliance

This No. 6 x 3/4" tapping screw features a 0.138" thread diameter with 19 TPI (threads per inch) and utilizes thread forming technology for plastic applications. The screw is manufactured to precise dimensional standards with a standard flat head profile and blunt tip design. For installation guidance, use with a 1/8" drill bit for proper hole preparation. 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.
