S-99512A159 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP7 drive, reducing cam-out and tool wear for efficient installation.
• Exceptional corrosion resistance provided by zinc-plated steel, ensuring long-term durability in various environments.
• Secure, vibration-resistant fastening in plastic materials due to the tri-lobe shank design that displaces material to form strong threads.
• High thread engagement with 28 threads per inch and full threading, delivering reliable holding power in plastic assemblies.
• Streamlined installation process with a blunt tip and standard pan head, allowing for easy alignment and consistent seating.
• Environmental compliance assurance by meeting RoHS 3 and REACH standards, supporting sustainable manufacturing practices.
• Optimized for plastic applications with a No. 2 thread diameter and recommended 5/64" drill bit, minimizing stress and cracking in delicate materials.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel TRS tapping screws are specifically engineered for plastic fastening challenges, where traditional screws may cause splitting or weak threads. The thread forming design with a tri-lobe shank displaces plastic material without cutting, creating strong, load-bearing threads that resist loosening under vibration. Combined with the Torx Plus IP7 drive, they enable higher torque application with minimal slippage, reducing assembly time and tool damage. Ideal for electronics enclosures, automotive trim, and consumer products, these screws ensure durable, reliable joints in plastic applications, enhancing product longevity and performance while adhering to strict industry standards.

Specification Summary & Compliance

This product features a No. 2 screw size with a thread diameter of 0.086" and 28 TPI, fully threaded for consistent grip. It complies with standard dimensional tolerances for inch-based tapping screws, including a right-hand thread direction and blunt tip for thread forming in plastics. The screws are manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they are free of hazardous substances and suitable for global supply chains.
