S-90380A299 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic with thread forming technology that creates strong, permanent threads without chipping or cracking materials.
• Enhanced corrosion resistance thanks to zinc-plated steel construction, ensuring long-term reliability in various environments.
• Easy installation and reduced cam-out with Phillips No. 2 drive and tri-lobe shank design for secure driving and minimal tool slippage.
• Optimal thread engagement with fully threaded design and 14 TPI, providing consistent fastening strength across the entire length.
• Wide compatibility with plastics using a standard No. 15 drill bit (0.18" diameter) for precise hole preparation and secure fits.
• Compliance with environmental standards including RoHS 3 and REACH, making them safe for industrial and commercial use.
• Durable rounded pan head that sits flush against surfaces, offering a clean finish and distributed load-bearing capacity.

Professional Applications & Engineering Value

These No. 10 x 1/4" zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The thread forming design with a tri-lobe shank displaces plastic material to create robust, high-strength threads without generating chips, reducing the risk of weak points or failure. This makes them ideal for industrial fastening in electronics, automotive components, and consumer goods where vibration resistance and longevity are critical. The Phillips drive ensures efficient installation with standard tools, while the zinc plating provides a protective barrier against corrosion, extending service life in demanding applications.
