S-90096A243 10-24 x 5/8" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• Effortless installation in tough materials like aluminum, brass, and cast iron, thanks to the thread-cutting (Type F) design that eliminates the need for pre-tapped holes.
• High torque application capability with an external hex/slotted head, providing secure driving and reducing tool slippage during assembly.
• Enhanced load distribution from the integrated flange, minimizing surface damage and improving joint integrity in sheet metal applications.
• Wide material compatibility with coarse UNC threads, offering strong holding power in various substrates without stripping.
• Full-length threading for consistent grip along the entire 5/8" length, maximizing fastening strength and vibration resistance.
• Regulatory peace of mind with compliance to ASME B18.6.3 and RoHS 3, ensuring safety and environmental standards are met.

Professional Applications & Engineering Value

This 10-24 UNC tapping screw is engineered to address common challenges in metalworking and assembly, such as material fatigue and installation inefficiency. Made from zinc-plated steel, it provides a durable barrier against oxidation, extending service life in demanding conditions like outdoor equipment or humid settings. The thread cutting (Type F) design allows for direct insertion into materials like aluminum, brass, and cast iron, reducing labor time and eliminating the risk of cross-threading. With a coarse thread and fully threaded shank, it ensures rapid engagement and superior pull-out resistance, making it ideal for high-vibration applications in automotive, machinery, and sheet metal fabrication. The external hex/slotted drive offers versatility for both power and manual tools, streamlining production lines while the flange distributes clamping force evenly, preventing surface deformation.

Specification Summary & Compliance

This screw adheres to Class 2A thread tolerances per UNC standards, ensuring precise fit and interchangeability. It meets ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy and performance, and is RoHS 3 (2015/863/EU) compliant, free from hazardous substances. Designed for use with a No. 19 drill bit (0.166" diameter), it guarantees optimal hole preparation. The right-hand, coarse thread and blunt tip further support reliable, repeatable fastening in industrial settings.
