S-90096A144 6-32 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, ensuring long-lasting performance in demanding industrial environments.
• Excellent material compatibility for reliable fastening in aluminum, brass, cast iron, and sheet metal without pre-tapped holes.
• Enhanced driving efficiency with combined external hex/slotted drive, allowing for high-torque application and versatile tool use.
• Increased holding power and stability due to the flanged design, which distributes load and prevents loosening under vibration.
• Quick and secure installation with coarse UNC threads and thread-cutting tip, reducing assembly time and improving joint integrity.
• Full threading for maximum grip along the entire 1/4" length, providing consistent clamping force in various material thicknesses.
• Reliable compliance and quality meeting ASME B18.6.3 standards and RoHS 3, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

These 6-32 UNC tapping screws are engineered to address common challenges in metalworking and assembly, such as stripping threads and corrosion-induced failure. Made from zinc-plated steel, they offer robust protection against rust, extending service life in humid or outdoor conditions. The thread-cutting design (Type F) allows for easy installation in ductile materials like aluminum, brass, and cast iron, eliminating the need for separate tapping operations and reducing labor costs. The coarse thread and flanged hex head enhance grip and distribute stress, preventing pull-out in sheet metal applications. Ideal for HVAC, automotive, and machinery assembly, these screws deliver consistent performance where vibration resistance and durability are critical.

Specification Summary & Compliance

This screw features a No. 6 size with 6-32 UNC coarse threads, fully threaded along a 1/4" length, and complies with ASME B18.6.3 dimensional and performance standards. Threads are right-hand direction with Class 2A fit for reliable engagement. The product is RoHS 3 (2015/863/EU) compliant, ensuring it meets environmental regulations for hazardous substance restrictions. Recommended drill bit size is No. 31 (0.12" diameter) for optimal thread formation in specified materials.
