S-90935A240 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel finish, extending service life in demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Optimized for sheet metal applications with pointed tip and fully threaded shank ensuring quick starts and maximum grip in materials up to 0.025" thick.
• Reliable drive performance from Phillips No. 2 drive style and pan head design, providing secure torque transfer and flush seating.
• Consistent dimensional accuracy with No. 10-12 thread specification and standard pan head profile for uniform performance across production runs.
• Enhanced material compatibility with A/AB thread forming type, minimizing cracking in thin gauge metals while maintaining high pull-out strength.
• Compliance-ready for global markets meeting RoHS 3 and REACH environmental standards, ensuring regulatory acceptance in industrial supply chains.

Professional Applications & Engineering Value

These Black-Oxide Steel tapping screws deliver critical engineering advantages in sheet metal fabrication and assembly operations. The thread forming design eliminates chip formation during installation, preventing contamination in electrical enclosures and precision machinery. With fully threaded construction and 12 threads per inch configuration, these Phillips pan head screws maintain consistent clamping force across the entire engagement length, solving vibration-induced loosening in automotive, HVAC, and electronic chassis applications. The pointed tip ensures precise alignment in pre-drilled holes using No. 21 drill bits, while the Black-Oxide coating provides essential corrosion protection in moderately corrosive environments, making these No. 10 tapping screws ideal for high-volume manufacturing requiring reliability and rapid installation.

Specification Summary & Compliance
