S-99512A162 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and reduced tool wear with the Torx Plus IP7 drive, ensuring secure fastening and minimal cam-out during installation.
• Excellent corrosion resistance provided by the zinc-plated steel material, extending the screw's lifespan in various industrial environments.
• Reliable, vibration-resistant fastening in plastic materials due to the thread-forming TRS design and tri-lobe shank, which creates strong, lasting threads without pre-tapping.
• Optimized for high-volume assembly with a fully threaded 1/2" length and 28 TPI, enabling quick installation and consistent hold in plastic substrates.
• Secure compliance with international environmental standards, meeting RoHS 3 and REACH requirements for safe and sustainable use.
• Easy alignment and reduced head protrusion with the standard pan head style, offering a low-profile finish for streamlined assemblies.
• Precision fit with recommended 5/64" drill bits, ensuring accurate pilot holes and minimizing the risk of material cracking during installation.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic fastening applications, such as thread stripping, material stress, and assembly inefficiency. The thread-forming design and tri-lobe shank cross-section displace plastic material to form durable, high-holding-power threads, eliminating the need for pre-tapped holes and reducing installation time. Combined with the Torx Plus IP7 drive, they provide exceptional torque transfer, minimizing driver slip and tool damage—critical for repetitive, high-torque assembly lines. Ideal for electronics enclosures, automotive trim, and consumer goods, these screws ensure reliable, vibration-resistant joints that maintain integrity under dynamic loads, enhancing overall product durability and performance.

Specification Summary & Compliance

This No. 2 screw features a 1/2" length, 28 TPI thread, and tri-lobe shank designed for thread-forming applications in plastics. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The zinc-plated steel construction and Torx Plus IP7 drive support consistent performance and ease of use in industrial settings.
