S-90122A335 1/4"-20 x 1 1/8" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.236" thickness in aluminum and sheet metal
• Superior corrosion resistance through ultra-corrosion-resistant coated alloy steel construction for extended service life in demanding environments
• Enhanced driving efficiency with external hex head design providing secure tool engagement and high torque transmission
• Permanent thread formation through thread forming (CSD) technology that creates strong, vibration-resistant threads in ductile materials
• Increased bearing surface with flanged design that distributes clamping force over wider area, reducing material stress
• Full-length thread engagement ensures maximum holding power along the entire fastener length for superior joint integrity
• Regulatory compliance assurance with RoHS 3 (2015/863/EU) compliance for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 1/4"-20 UNC thread forming tapping screws deliver exceptional engineering value in aluminum and sheet metal applications where traditional fastening methods fall short. The ultra-corrosion-resistant alloy steel construction combined with thread forming technology addresses critical industrial challenges by eliminating the need for separate tapping operations and pre-drilled holes. The external hex drive ensures reliable installation in high-torque scenarios, while the No. 4 drilling tip penetrates materials up to 0.236" thick, significantly reducing assembly time and labor costs. The flanged design provides superior load distribution, preventing material deformation and maintaining joint integrity in vibration-prone environments common in automotive, HVAC, and electronic enclosure applications.

Specification Summary & Compliance

These thread forming tapping screws feature 1/4"-20 UNC coarse threads with right-hand orientation and fully threaded configuration for maximum engagement. Manufactured to precise dimensional standards with Class 2A thread tolerances, these CSD type screws ensure consistent performance across production runs. The product meets RoHS 3 (2015/863/EU) compliance requirements, confirming adherence to environmental regulations while maintaining the mechanical properties necessary for demanding industrial applications.
