S-90087A865 10-24 x 7/8" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior material strength and corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Efficient self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes and reducing assembly time in materials like aluminum and cast iron.
• Reliable drive engagement featuring a Phillips No. 2 drive style, providing secure torque transmission and minimizing cam-out during installation.
• Optimized thread grip with coarse UNC 10-24 threading and full threading along the 7/8" length, delivering strong holding power in sheet metal and other soft materials.
• Enhanced durability and consistent performance backed by compliance with ASME B18.6.3 and SAE J933 standards, ensuring dimensional accuracy and interchangeability.
• Versatile application compatibility designed for use with a No. 19 drill bit, facilitating precise hole preparation in brass, aluminum, and cast iron without stripping.
• Secure fastening with a standard pan head offering a rounded profile for a flush or slightly raised finish, improving load distribution and aesthetic integration.

Professional Applications & Engineering Value

These 10-24 zinc-plated steel tapping screws are engineered to address common challenges in metalworking and assembly, such as thread stripping and inconsistent fastening in soft materials. The thread cutting design (Type F) and coarse UNC threading enable the screws to form precise, durable threads in aluminum, brass, cast iron, and sheet metal without pre-tapping, reducing labor and tooling costs. The zinc plating provides a protective barrier against corrosion, extending service life in humid or outdoor settings. Ideal for HVAC systems, automotive panels, and machinery enclosures, these screws ensure reliable, vibration-resistant connections that maintain integrity under stress, supported by their ASME B18.6.3 compliance for consistent quality and performance.

Specification Summary & Compliance

This product adheres to Class 2A thread tolerances under the UNC coarse thread standard, with a right-hand thread direction and fully threaded shank for uniform engagement. Manufactured in accordance with ASME B18.6.3 and SAE J933 specifications, it guarantees dimensional precision and mechanical reliability. The screws are designed for use with a No. 19 drill bit (0.166" diameter) and meet common industry requirements for material safety, though specific RoHS or REACH declarations should be verified per batch. The zinc-plated steel construction supports compliance with general corrosion resistance standards, making these screws suitable for a wide range of industrial fastening applications.
