S-90096A148 6-32 x 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior Thread Cutting Performance – Efficiently forms threads in aluminum, brass, cast iron, and sheet metal without pre-tapping, reducing installation time and labor costs.
• Enhanced Corrosion Resistance – Zinc-plated steel construction provides reliable protection against rust, extending service life in demanding industrial environments.
• Secure Flanged Design – Integrated flange distributes clamping force evenly, minimizing the risk of material damage and improving joint integrity.
• Optimized Drive Compatibility – External hex/slotted drive allows for high-torque application with standard tools, ensuring quick and secure fastening.
• Coarse UNC Thread Profile – Delivers faster installation and superior holding power in soft materials, reducing the chance of cross-threading.
• Full Thread Engagement – Fully threaded shank maximizes grip along the entire length, providing consistent load distribution and vibration resistance.
• Precision Drill Bit Compatibility – Designed for use with No. 31 drill bit (0.12" diameter), ensuring accurate pilot holes and reliable thread formation.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 6-32 zinc-plated steel tapping screw excels in fastening aluminum, brass, cast iron, and sheet metal components. Its thread cutting design eliminates the need for separate tapping operations, streamlining assembly processes and reducing production costs. The coarse UNC thread ensures rapid installation and robust holding strength, even in softer materials prone to stripping. With a flanged head and external hex/slotted drive, it offers superior torque transmission and prevents over-tightening, making it ideal for high-vibration environments like automotive assemblies, machinery enclosures, and metal fabrication projects. The zinc plating adds a protective barrier against corrosion, ensuring long-term reliability in both indoor and moderately exposed settings.
