S-90935A155 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel construction, extending service life in demanding industrial environments
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping
• Optimized for sheet metal applications with precise 18 TPI threading and pointed tip for smooth penetration
• Secure fastening performance with fully threaded design ensuring maximum grip along the entire shank length
• Enhanced drive stability featuring Phillips No. 2 drive for reliable torque transmission and reduced cam-out risk
• Maximum material compatibility designed for 0.025" maximum drilling thickness in sheet metal assemblies
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These black-oxide steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger thread engagement than conventional cutting screws. The fully threaded design ensures consistent clamping force distribution across the entire fastener length, preventing loosening under vibration - a critical advantage in automotive, electronics enclosure, and HVAC applications. The Phillips pan head configuration provides a low-profile finish that sits flush against surfaces while offering sufficient drive engagement for high-torque applications. Engineered specifically for 0.138" thread diameter with 18 TPI precision, these screws maintain dimensional accuracy across high-volume production runs, ensuring repeatable performance in automated assembly systems.

Specification Summary & Compliance

These No. 6 x 1-1/4" tapping screws feature precision Class 2A thread tolerances with right-hand threading and A/AB tapping screw standards. The manufacturing process adheres to strict quality controls for dimensional accuracy, including 0.27" head diameter and 0.097" head height specifications. Compatibility is verified with No. 32 drill bit (0.116" diameter) for optimal performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures these fasteners meet the latest environmental and safety standards for industrial use worldwide.
