S-99397A124 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic through thread forming technology that creates strong, permanent threads without chips.
• Enhanced corrosion resistance with a zinc-plated steel finish, ensuring long-term reliability in various environments.
• High-torque driving and reduced cam-out with the Torx Plus IP5 drive, allowing for secure installation and minimizing tool slippage.
• Excellent material displacement and vibration resistance due to the tri-lobe shank cross-section, providing a secure, reliable fit.
• Streamlined assembly process with a fully threaded, 6mm length design for consistent performance and quick installation.
• Broad compatibility with standard No. 54 drill bits (0.055"), simplifying the preparation of pilot holes in plastic components.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global markets.

Professional Applications & Engineering Value

This M1.59 x 6mm TRS tapping screw is engineered specifically for high-performance fastening in plastic materials. Its thread forming (Tapping Method: Thread Forming) design eliminates the need for tapped holes and prevents material cracking by displacing plastic to form strong, clean internal threads. The tri-lobe shank cross-section enhances grip and resists loosening under vibration, a common challenge in automotive electronics, consumer appliance housings, and telecommunications equipment. The zinc-plated steel construction provides a durable, corrosion-resistant finish, while the Torx Plus IP5 drive offers superior torque transfer, reducing assembly time and preventing head stripping. This combination delivers reliable, long-lasting joints in demanding plastic assembly applications.

Specification Summary & Compliance
