S-94209A150 10-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and reduced cam-out with Torx Plus drive (IP25/T25) for efficient installation and minimal tool wear
• Excellent corrosion resistance provided by zinc-plated steel construction, extending service life in various industrial environments
• Reliable thread forming in soft materials like aluminum, brass, and copper, ensuring secure fastening without pre-tapping
• Enhanced grip and vibration resistance from the Tri-Lobe shank design, preventing loosening under dynamic loads
• Precise fit and reduced assembly errors with UNF fine threads and 1/2" length, offering consistent performance in tight spaces
• Broad material compatibility with standard No. 21 drill bit (0.159" diameter), simplifying hole preparation and installation
• Compliance with environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

These 10-32 thread forming screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or require additional tapping. The zinc-plated steel material offers durability against corrosion, while the Torx Plus drive minimizes cam-out, allowing for higher torque application without damaging the drive recess. The Tri-Lobe shank and fully threaded design enhance pull-out resistance and distribute stress evenly, reducing the risk of material deformation in soft metals. Ideal for electronics, automotive, and HVAC assemblies, these screws streamline production by eliminating the need for separate tapping steps, saving time and labor costs in high-volume manufacturing.

Specification Summary & Compliance

This product adheres to UNF fine thread standards with a thread size of 10-32 and length of 1/2" (tolerance: -0.03" to 0"). It features a Class 2A thread fit for general applications, right-hand thread direction, and a blunt tip for easy alignment. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it meets strict environmental and health safety regulations for industrial use.
