S-94209A080 6-32 x 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP15 drive, reducing cam-out and tool wear for reliable installation in high-volume applications.
• Excellent corrosion resistance provided by the zinc-plated steel construction, ensuring long-term durability in various industrial environments.
• Exceptional holding power achieved through the Tri-Lobe shank cross-section, which creates a secure, vibration-resistant fit in softer materials.
• Efficient thread forming in aluminum, brass, and copper without pre-tapping, saving time and labor costs in assembly processes.
• Wide material compatibility with UNC coarse threads and a blunt tip, designed specifically for use in non-ferrous metals like aluminum, brass, and copper.
• Consistent and precise installation due to the fully threaded design and controlled length tolerance, ensuring repeatable performance.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industrial and international markets.

Professional Applications & Engineering Value

This zinc-plated steel tapping screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The thread forming design eliminates the need for a pre-tapped hole, reducing production steps and the risk of cross-threading. The Tri-Lobe shank displaces material during installation to create a tight, permanent thread with high resistance to vibrational loosening. Combined with the Torx Plus IP15 drive, it allows for higher torque application with minimal slippage, making it ideal for automated assembly lines and applications where screw integrity is critical. Its UNC coarse thread and blunt tip are optimized for softer, non-ferrous metals, providing a reliable, durable fastening solution for electronics enclosures, HVAC systems, and automotive components.

Specification Summary & Compliance

This screw conforms to UNC coarse thread standards with a size of 6-32 and a length of 1/4" (with a length tolerance of -0.03" to 0"). The thread forming tapping method and fully threaded design ensure consistent performance. It is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for industrial use.
