S-90434A172 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in various industrial environments.
• Exceptional holding power in plastic materials due to the thread forming TRS design and Tri-Lobe shank, reducing the risk of pull-out and stripping.
• Streamlined assembly process with Phillips No. 2 drive, ensuring easy installation and reducing tool slippage.
• Clean, flush finish achieved with the standard flat head and 82° countersink angle, ideal for applications requiring a smooth surface.
• Reliable thread engagement through fully threaded blunt tip design, providing consistent fastening in plastic substrates.
• Compliance with stringent environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in global markets.
• Optimized for use with No. 15 drill bit (0.18" diameter), facilitating precise hole preparation and secure fastening in plastic assemblies.

Professional Applications & Engineering Value

These No. 10 x 3/4" zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic assembly, such as material cracking and insufficient thread retention. The thread forming technology and Tri-Lobe shank cross-section displace plastic material without cutting, creating strong, vibration-resistant threads that enhance joint integrity. The zinc plating offers a protective barrier against corrosion, crucial for industrial and outdoor applications. With a Phillips drive and standardized dimensions, these screws enable efficient, high-volume installation in automotive trim, electronic enclosures, and consumer products, reducing assembly time and improving product durability.

Specification Summary & Compliance

This thread forming screw features a No. 10 size with 3/4" length, 0.19" thread diameter, and approximately 14 threads per inch, adhering to standard inch measurements for precision. The flat head with 82° countersink angle ensures proper seating in prepared holes. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious manufacturing processes and global supply chains.
