S-90096A322 10-32 x 1/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Effortless installation and high torque capability thanks to the external hex drive and flanged design, reducing assembly time and providing a secure, wide-bearing surface.
• Reliable thread-forming performance in materials like aluminum, brass, and cast iron, creating strong, permanent threads without pre-tapping.
• Full threading along the shank ensures maximum grip and uniform stress distribution for a more secure and vibration-resistant fastening.
• Precision-engineered UNF fine threads offer a tighter seal and improved resistance to loosening under dynamic loads compared to coarse threads.
• Compliance with ASME B18.6.3 standards guarantees dimensional accuracy, interchangeability, and consistent performance for professional applications.
• RoHS 3 compliance ensures the product meets stringent environmental regulations, making it suitable for global supply chains.

Professional Applications & Engineering Value

This 10-32 UNF thread cutting screw is engineered to solve common fastening challenges in materials like aluminum, brass, cast iron, and sheet metal. Its Type F tapping screw design with a thread cutting method efficiently forms its own mating thread, eliminating the need for a pre-tapped hole and reducing assembly steps. The zinc-plated steel material provides a durable barrier against corrosion, essential for components exposed to harsh conditions. The combination of a flanged head and external hex drive offers a larger bearing surface for improved load distribution and allows for high-torque installation with standard tools, preventing head stripping. This makes it an ideal heavy-duty fastener for automotive, machinery, and metal fabrication applications where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance
