S-90063A170 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Enhanced installation efficiency with pointed tip design that eliminates pre-drilling requirements in sheet metal applications
• Secure anti-rotation locking through serrated flange design that prevents loosening under vibration and dynamic loads
• Optimal thread engagement with fully threaded 1/2" length providing maximum holding power in thin materials
• High-torque installation capability with 1/4" external hex head allowing for powerful driving with standard tools
• Precision thread forming action that creates strong, permanent threads in 0.05" maximum thickness materials
• Reliable performance with 16 threads per inch configuration ensuring consistent fastening in sheet metal assemblies

Professional Applications & Engineering Value

These No. 7 thread forming tapping screws deliver exceptional value in sheet metal applications where vibration resistance and material integrity are critical. The zinc-plated steel construction provides reliable corrosion protection while maintaining the strength needed for industrial environments. The needle point design combined with thread forming technology eliminates chip formation during installation, preventing contamination in sensitive assemblies. The serrated flange beneath the 1/4" hex head creates positive locking action, making these industrial fasteners ideal for automotive, HVAC, and electronic enclosure applications where vibration-induced loosening is a common concern. The compatibility with No. 30 drill bits (0.1285" diameter) ensures precise hole preparation for optimal thread engagement in materials up to 0.05" thickness.

Specification Summary & Compliance

These precision thread forming screws feature right-hand threading with 16 threads per inch and are designed for use with No. 30 drill bits (0.1285" diameter). The fully threaded No. 7 size screws maintain consistent Class 2A thread tolerances for reliable performance. Manufactured from zinc-plated steel with external hex/slotted drive style and serrated locking flange, these fasteners comply with industry standards for sheet metal applications. The product meets RoHS and REACH compliance requirements for use in various industrial and construction environments.
