S-90096A313 8-32 x 1 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior Thread Cutting Performance – Self-tapping design eliminates the need for pre-tapped holes, reducing installation time and labor costs in aluminum, brass, cast iron, and sheet metal.
• Enhanced Corrosion Resistance – Zinc-plated steel construction provides reliable protection against rust, extending service life in demanding industrial environments.
• Secure Flanged Hex Head Design – Integrated flange distributes load evenly and prevents pull-through, while the external hex drive allows for high-torque application with standard tools.
• Full Threading for Maximum Holding Power – Complete thread coverage ensures strong, vibration-resistant fastening across the entire 1-1/2" length.
• Coarse UNC Threads for Quick Assembly – 8-32 UNC coarse thread profile enables faster driving and reduced cross-threading risk in soft materials.
• Industry Standard Compliance – Manufactured to ASME B18.6.3 specifications, guaranteeing consistent quality, dimensional accuracy, and interchangeability.
• Environmentally Responsible – RoHS 3 compliant, ensuring safe use in regulated applications without hazardous substances.

Professional Applications & Engineering Value

Engineered for heavy-duty fastening in non-ferrous metals and sheet assemblies, these thread cutting screws solve common installation challenges by forming their own threads without pre-tapping. The zinc-plated steel material offers excellent durability against corrosion, while the flanged hex head design provides a larger bearing surface to prevent damage to soft substrates like aluminum and brass. Ideal for industrial assembly lines, HVAC systems, and machinery where vibration resistance and quick installation are critical. The coarse UNC thread and blunt tip ensure reliable engagement in cast iron and sheet metal, reducing the risk of stripping and improving long-term joint integrity.
