S-90063A146 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring longevity in demanding industrial environments.
• Enhanced driving versatility through the external hex/slotted drive, allowing use with multiple tools for efficient installation.
• Reliable vibration resistance provided by serrated locking features, maintaining secure fastening in high-stress sheet metal assemblies.
• Optimized thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and costs.
• Full threading and pointed tip enable quick, precise starts and consistent holding power across the entire 3/8" length.
• Flanged head design distributes load evenly, minimizing surface damage and improving joint integrity in thin materials.
• Precision compatibility with No. 32 drill bits for up to 0.05" thickness, ensuring accurate fits and reduced material failure risks.

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws are engineered to address common challenges in sheet metal applications, such as material stripping and loosening under vibration. The thread forming design displaces material to form durable threads, eliminating the need for tapped holes and speeding up production lines. Made from zinc-plated steel, they resist rust and corrosion in harsh conditions, while the external hex/slotted drive offers flexibility for both manual and powered tools. The fully threaded body and needle point ensure quick penetration and uniform stress distribution, making them ideal for HVAC, automotive, and electronics enclosures where reliability is critical.

Specification Summary & Compliance
