S-95893A227 Length 25 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• High-torque installation capability thanks to Torx T15 drive design that minimizes cam-out and tool wear
• Flush, professional finish achieved through 90° countersink angle that sits perfectly flush with material surfaces
• Reliable thread formation in plastic materials using TRS thread-forming design that eliminates need for pre-tapped holes
• Full-length threading provides maximum holding power and consistent engagement throughout the entire fastener length
• Precision dimensional control with M3.5 metric sizing and 1.57mm thread pitch for exact fit in plastic components
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These M3.5 TRS tapping screws deliver exceptional value in plastic assembly applications where material integrity and installation efficiency are critical. The 18-8 stainless steel composition provides excellent corrosion resistance while maintaining sufficient ductility for the thread forming process. The Torx T15 drive system addresses common installation challenges in automated assembly lines by preventing driver slippage and enabling higher torque application without damaging the screw head. The 90° countersink angle ensures clean, flush mounting in plastic enclosures, electronic housings, and automotive trim components. Engineered specifically for plastic applications, these screws create strong, vibration-resistant threads without generating chips or debris that could compromise sensitive electronic components.

Specification Summary & Compliance

These metric thread forming screws feature M3.5 diameter with 25mm length and 1.57mm thread pitch, manufactured to precise dimensional standards for consistent performance. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications for plastic materials. Compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions. Installation requires No. 34 drill bit (0.111" diameter) for proper hole preparation in plastic substrates.
