S-90096A624 3/8"-16 x 1" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior thread cutting performance in aluminum, brass, cast iron, and sheet metal for reliable fastening in diverse industrial materials.
• Zinc-plated steel construction provides excellent corrosion resistance, extending service life in harsh environments.
• Flanged hex head design eliminates the need for a separate washer, simplifying installation and increasing load distribution.
• UNC coarse threads ensure faster installation and reduced risk of cross-threading in coarse-grained materials.
• Fully threaded shank maximizes grip length and pull-out resistance for secure, vibration-resistant connections.
• External hex drive allows for high-torque application with standard tools, speeding up assembly processes.
• Precision-engineered dimensions (1" length, 3/8"-16 thread) ensure consistent fit and performance in pre-drilled holes (Drill Bit Size R).

Professional Applications & Engineering Value

This heavy-duty flanged hex tapping screw is specifically engineered to address common challenges in metal fabrication and assembly. Its thread-cutting design creates precise mating threads in materials like aluminum, brass, and cast iron without pre-tapping, significantly reducing installation time and labor costs. The zinc-plated steel material offers robust durability against wear and environmental factors, while the flanged head provides superior clamping force and eliminates washer slippage. Ideal for sheet metal applications, automotive components, and machinery assembly, it ensures reliable, long-lasting fastening in high-stress environments where vibration resistance and structural integrity are critical.

Specification Summary & Compliance

This screw features UNC coarse threads (3/8"-16) with standard dimensional accuracy, ensuring compatibility with industry-standard nuts and threaded holes. It is manufactured in compliance with ASME B18.6.3 and SAE J933 specifications, guaranteeing consistent quality and performance. The product is also RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for hazardous substance restrictions. Designed for use with a Drill Bit Size R (0.339" diameter), it provides precise fitment and optimal thread engagement in pre-drilled applications.
