S-99397A359 Length 14 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP8 drive that minimizes cam-out and tool wear for reliable fastening
• Excellent corrosion resistance provided by 18-8 stainless steel construction for long-term durability in harsh environments
• Secure thread formation in plastic materials through the Tri-Lobe shank design that creates strong, permanent threads without cracking
• Reduced installation effort with thread forming (TRS) technology that eliminates the need for pre-tapped holes
• Consistent performance ensured by fully threaded M2.63 design and blunt tip for precise depth control
• Enhanced worker safety through compliance with RoHS 3 and REACH environmental regulations
• Optimized for plastic applications with specialized thread pitch and diameter matching industry-standard drill sizes

Professional Applications & Engineering Value

This M2.63 thread forming screw delivers exceptional engineering value in plastic fastening applications where material integrity is paramount. The 18-8 stainless steel construction provides superior corrosion resistance for outdoor equipment, automotive components, and electronic enclosures exposed to moisture or chemicals. The Tri-Lobe shank design displaces plastic material during installation, creating strong, permanent threads without the stress concentrations that cause cracking in brittle polymers. With the Torx Plus IP8 drive system, manufacturers achieve higher torque transmission compared to conventional drives, reducing assembly time and improving production efficiency. The combination of thread forming technology and metric precision makes these tapping screws ideal for high-volume manufacturing where reliability and consistency are critical.

Specification Summary & Compliance

This metric tapping screw features M2.63 diameter with 14mm length and approximately 1.06mm thread pitch, designed for use with No. 43 drill bit (0.089" diameter). The thread forming (TRS) screw utilizes right-hand threading and fully threaded design with standard pan head profile. Manufactured to precise dimensional standards, this fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
