S-90055A192 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread-forming installation with Type B design creates strong, permanent threads in sheet metal without pre-tapping
• Optimal flush mounting featuring an 82° countersink angle and undercut flat head for seamless surface finishing
• Enhanced driving efficiency with Phillips No. 2 drive style providing secure tool engagement and reduced cam-out
• Maximum holding power through fully threaded right-hand design with 18 threads per inch for superior grip in thin materials
• Simplified installation process requiring only a No. 29 drill bit (0.136" diameter) for precise hole preparation
• Environmental compliance assurance meeting RoHS 3 standards for restricted substance control

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal assembly applications where vibration resistance and permanent fastening are critical. The Type B thread forming technology eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The undercut flat head profile with 82° countersink angle ensures flush mounting without protrusion, ideal for applications requiring smooth surface finishes. The fully threaded design provides consistent clamping force along the entire fastener length, while the Phillips drive system offers reliable torque transmission for high-volume production environments. These industrial fasteners are engineered to withstand the rigors of metal fabrication, HVAC systems, and electronic enclosures where reliable, long-term performance is essential.

Specification Summary & Compliance

These No. 8 x 3/8" tapping screws feature precise 0.164" thread diameter with 18 threads per inch in right-hand orientation. The fastener meets standard thread forming specifications for Type B tapping screws with proper clearance hole preparation using a No. 29 drill bit (0.136" diameter). Manufacturing complies with RoHS 3 (2015/863/EU) regulations for environmental safety, ensuring suitability for various industrial applications without hazardous substance concerns.
