S-93882A231 10-32 x 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• Enhanced load distribution and vibration resistance thanks to the integrated flange design, reducing the risk of loosening under stress.
• High-strength thread forming capability creates secure, permanent threads in materials like steel, aluminum, and cast iron without pre-tapping.
• Easy installation and removal with an external hex drive, allowing for high torque application with standard tools.
• Optimal thread engagement and holding power from UNF fine threading, providing a tight, precise fit in critical assemblies.
• Versatile material compatibility for use in steel, aluminum, brass, cast iron, and sheet metal, streamlining inventory for diverse projects.
• Full threading along the shank ensures maximum grip and uniform stress distribution across the entire fastener length.

Professional Applications & Engineering Value

These 10-32 zinc-plated steel flanged hex tapping screws are engineered to address common challenges in metalworking and assembly, such as material fatigue and thread stripping. The thread forming (SW) design displaces material to create strong, burr-free internal threads, eliminating the need for separate tapping operations and reducing installation time. This is particularly valuable in steel, aluminum, and sheet metal applications where precise, high-strength fastening is critical. The UNF fine thread and flange feature work together to distribute clamp load evenly, resist vibration loosening, and provide a reliable seal in dynamic environments. Paired with a No. 17 drill bit (0.173" diameter), these screws ensure consistent performance in automotive, machinery, and structural assemblies, enhancing productivity and reducing maintenance costs.
