S-99397A448 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and reduced cam-out with the Torx Plus IP10/T10 drive, ensuring reliable fastening in repetitive assembly operations.
• Excellent corrosion resistance provided by 18-8 Stainless Steel material, ideal for applications exposed to moisture or harsh environments.
• High-strength thread forming action with the Tri-Lobe shank design, creating secure, vibration-resistant threads in plastic without pre-tapping.
• Optimized for plastic assemblies with a blunt tip and 1.27mm pitch, minimizing stress cracking and ensuring consistent holding power.
• Streamlined installation process using a standard No. 37 drill bit, reducing setup time and improving production efficiency.
• Enhanced durability and compliance with RoHS 3 and REACH standards, meeting strict environmental and safety regulations for global supply chains.
• Secure and flush fit due to the pan head design and fully threaded shank, providing a clean finish and uniform clamping force.

Professional Applications & Engineering Value

These M3.12 TRS thread forming screws are engineered to address common challenges in plastic assembly, such as material cracking and thread stripping. The Tri-Lobe shank cross-section and thread forming (TRS) design displace plastic material to create strong, permanent internal threads, eliminating the need for inserts and reducing part count. Made from 18-8 Stainless Steel, they offer reliable performance in corrosive environments, while the Torx Plus drive (IP10/T10) ensures high torque transfer with minimal tool wear. Ideal for plastic fastening in electronics enclosures, automotive components, and consumer goods, these screws enhance assembly integrity and long-term reliability.

Specification Summary & Compliance
