S-90086A675 10-24 x 3/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior thread cutting performance with F-type design ensures secure, vibration-resistant fastening in aluminum, brass, cast iron, and sheet metal without pre-tapping.
• Enhanced corrosion resistance from the black-oxide steel finish prolongs service life in demanding industrial environments.
• Optimized drive engagement with No. 2 Phillips flat head allows for efficient installation and reduced cam-out risk during high-torque applications.
• Full threading along the 3/4" length provides maximum grip and uniform load distribution across the entire fastened material.
• Coarse UNC thread profile enables quick installation and reliable holding power in soft metals and sheet materials.
• Compliance with ASME B18.6.3 standards guarantees dimensional accuracy, interchangeability, and consistent quality for industrial assemblies.
• RoHS 3 environmental compliance ensures safe use in regulated industries and global market accessibility.

Professional Applications & Engineering Value

These 10-24 UNC thread cutting screws are precision-engineered to address common challenges in metalworking and assembly lines. The black-oxide steel construction offers a durable, rust-inhibiting layer that withstands exposure to moisture and industrial chemicals, reducing maintenance costs. The F-type tapping screw design with a blunt tip and coarse threads efficiently cuts mating threads in materials like aluminum, brass, cast iron, and sheet metal, eliminating the need for separate tapping operations and speeding up production. The Phillips flat head sits flush with surfaces, preventing snagging and ensuring a clean finish in automotive, HVAC, and machinery applications. By integrating ASME B18.6.3 specifications, these screws deliver reliable performance in high-vibration environments, minimizing loosening and enhancing structural integrity.

Specification Summary & Compliance

This product adheres to UNC coarse thread standards with a size of 10-24 and a length of 3/4", featuring full threading and a standard 82° countersink angle for flat head installation. Manufactured in compliance with ASME B18.6.3 dimensional and mechanical requirements, it ensures consistent Class 2A thread fit and interchangeability. The screws are RoHS 3 (2015/863/EU) compliant, meeting environmental regulations for hazardous substance restrictions, and are suitable for use with a No. 17 drill bit (0.173" diameter) as specified for thread cutting applications.
