S-90925A251 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum torque transfer and reduced tool slippage thanks to T25 Torx drive design that prevents cam-out during installation
• Excellent holding power in sheet metal through thread forming technology that creates strong, permanent threads without pre-tapping
• Full-length thread engagement provides consistent clamping force along the entire 1-1/2" length for secure fastening
• Optimized for sheet metal applications with pointed tip and No. 10-12 thread specification for easy starting and reliable performance
• Pan head design offers a low-profile finish while providing good bearing surface for secure fastening
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe industrial use worldwide

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliability and durability are paramount. The thread forming design eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening and provide superior pull-out strength. The T25 Torx drive system ensures maximum torque transmission during installation, reducing operator fatigue and preventing damage to screw heads in high-volume production environments. With their fully threaded No. 10-12 specification and 1-1/2" length, these sheet metal fasteners deliver consistent performance in HVAC systems, electrical enclosures, automotive components, and industrial machinery where secure metal-to-metal connections are critical.

Specification Summary & Compliance

These No. 10 tapping screws feature a 0.19" thread diameter with approximately 12 threads per inch in right-hand orientation. The pan head design measures 0.373" in diameter with 0.133" height, compatible with No. 21 drill bit (0.159" diameter) for maximum 0.025" drilling thickness. Manufactured as A/AB type thread forming screws with fully threaded shank and pointed tip. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications.
