S-96024A420 1/4"-20 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior material durability with 410 stainless steel construction, offering excellent corrosion resistance for long-lasting performance in demanding environments.
• Efficient self-tapping installation through the Thread Cutting Type F design, eliminating the need for pre-tapped holes and reducing assembly time in brass, cast iron, and sheet metal.
• Enhanced grip and load distribution from the integrated flange, minimizing surface damage and providing a secure, vibration-resistant fastening solution.
• Reliable drive engagement with the external hex head, allowing for high-torque application using standard tools to ensure tight, consistent installations.
• Optimized thread engagement with coarse UNC 1/4"-20 threads and full threading, delivering strong holding power and quick insertion in various materials.
• Precision compatibility using a No. 1 drill bit (0.228" diameter), ensuring accurate hole sizing for reduced risk of stripping or material failure.
• Compliance with global standards including RoHS 3 and REACH, ensuring environmental safety and suitability for international industrial applications.

Professional Applications & Engineering Value

This thread cutting tapping screw is engineered to address common challenges in metalworking, such as material brittleness and assembly efficiency. Made from 410 stainless steel, it resists rust and wear, making it ideal for harsh conditions in automotive, machinery, and construction sectors. The coarse UNC thread and thread cutting design enable quick, secure fastening in brass, cast iron, and sheet metal without pre-threading, reducing labor costs and preventing thread wear. The flanged hex head enhances stability and distributes load evenly, minimizing surface deformation. With a fully threaded shank and right-hand direction, it ensures maximum grip and ease of use in high-vibration environments, supporting reliable, long-term performance in critical B2B applications.
