S-95893A621 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Enhanced drive security and reduced cam-out with the T6 Torx drive, allowing for higher torque application and preventing tool slippage.
• Efficient, high-strength thread forming in plastics using the Tri-Lobe shank design, creating strong, reliable threads without pre-tapping.
• Clean, flush installation with the standard flat head and 82° countersink angle, providing a smooth finish and reducing snagging.
• Optimized for plastic assembly with a blunt tip and right-hand thread, minimizing material stress and cracking during installation.
• High thread density with 28 threads per inch for maximum holding power and vibration resistance in plastic substrates.
• Compliance with global environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This T6 Torx Flat Head TRS tapping screw is precision-engineered to address common challenges in plastic assembly, such as material cracking and stripped threads. The 18-8 Stainless Steel provides excellent durability and corrosion resistance, making it suitable for electronics, automotive components, and outdoor equipment. Its Tri-Lobe shank and thread-forming design displace plastic material to create robust, permanent threads without the need for a separate tapping operation, significantly reducing assembly time and improving joint integrity. The combination of a blunt tip and high thread density (28 TPI) ensures minimal stress concentration, preventing damage to delicate plastic housings and ensuring reliable performance under vibration and thermal cycling.
