S-99397A349 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• High-torque assembly capability via Torx Plus IP8 drive, minimizing cam-out and tool wear for efficient installations.
• Secure, vibration-resistant fastening in plastic materials due to the tri-lobe shank design that displaces material without cracking.
• Optimized for plastic applications with a blunt tip and thread-forming (TRS) design, reducing stress and preventing material splitting.
• Full thread engagement along the 6mm length for maximum holding power and uniform load distribution.
• Precision compatibility with No. 43 drill bits (0.089"), ensuring accurate hole sizing and consistent performance.
• Environmental and regulatory safety with full compliance to RoHS 3 and REACH, supporting sustainable manufacturing practices.

Professional Applications & Engineering Value

Engineered for plastic assembly challenges, these M2.63 thread forming screws deliver exceptional value in electronics, automotive trim, and consumer goods. The 18-8 stainless steel material provides excellent resistance to oxidation and chemicals, ideal for outdoor or humid conditions. With a Torx Plus IP8 drive, operators achieve higher torque application without slippage, reducing assembly time and tool maintenance. The tri-lobe shank and TRS thread forming technology create strong, permanent threads in plastic substrates, eliminating the need for inserts and reducing component failure risks. This design ensures reliable performance in right-hand threaded applications where vibration resistance and pull-out strength are critical.

Specification Summary & Compliance

This metric tapping screw adheres to standard dimensional tolerances for M2.63 size with an approximate thread pitch of 1.06mm and a fully threaded, blunt tip configuration. The pan head style offers a low-profile, rounded finish for aesthetic and functional needs. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring the absence of hazardous substances and supporting global supply chain requirements.
