S-90087A859 8-32 x 2" 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 in tough materials thanks to the Type F thread-cutting design that eliminates the need for pre-tapping in aluminum, brass, cast iron, and sheet metal.
• High-torque driving capability with the Phillips No. 2 drive, reducing cam-out and tool slippage for faster, more reliable assembly.
• Maximum grip and holding power from the fully threaded UNC coarse spacing, ensuring a secure, vibration-resistant fastening in coarse-grained materials.
• Broad compatibility and reliable performance by conforming to ASME B18.6.3 specifications, guaranteeing dimensional accuracy and interchangeability.
• Streamlined, low-profile head design with a standard pan head, providing a flush or slightly raised finish that minimizes snagging in assembled products.
• Optimized for high-strength applications with a 2-inch length and No. 8 screw size, offering deep penetration and robust clamping force for heavy-duty assemblies.

Professional Applications & Engineering Value

Engineered for challenging metalworking and fabrication environments, these Type F tapping screws solve common installation headaches by cutting their own threads directly into materials like aluminum, brass, cast iron, and sheet metal. The zinc-plated steel construction provides a durable barrier against rust and corrosion, essential for outdoor equipment, HVAC systems, and industrial machinery. The UNC coarse thread and fully threaded design ensure rapid installation and superior pull-out resistance, reducing labor time and improving joint integrity. With a Phillips drive and pan head, these screws offer a balance of drive efficiency and a clean aesthetic, making them ideal for both structural assemblies and finished product applications where reliability and speed are critical.

Specification Summary & Compliance

This 8-32 x 2" tapping screw adheres to Class 2A dimensional tolerances for UNC threads and is manufactured in compliance with ASME B18.6.3 and SAE J933 specifications, ensuring consistent quality and performance. The screw features a right-hand thread direction, coarse spacing, and a blunt tip optimized for thread-cutting applications. It is designed for use with a No. 20 drill bit (0.147" diameter) and meets industry standards for material and mechanical properties, providing a reliable, specification-compliant fastening solution for professional use.
