S-94209A590 10-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-coated steel construction for extended service life in demanding environments.
• Enhanced torque transmission and reduced cam-out using the Torx Plus IP25 drive, ensuring secure fastening and minimizing tool wear.
• Excellent thread-forming capability in softer materials like aluminum, brass, and copper, creating strong, reliable threads without pre-tapping.
• Maximum holding power from the fully threaded design and Tri-Lobe shank, which provides superior resistance to pull-out and vibration.
• Precise fastening with UNF fine threads for a tighter fit and improved sealing in applications where coarse threads are not suitable.
• Streamlined compliance with RoHS 3 and REACH regulations, ensuring they meet strict international environmental and safety standards.
• Optimized for efficiency with a standard pan head and blunt tip for easy alignment and consistent installation depth.

Professional Applications & Engineering Value

This 10-32 thread forming screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The black corrosion-resistant coated steel material provides durable protection against oxidation, crucial for outdoor or high-moisture industrial settings. Its Tri-Lobe shank design displaces material during installation, creating a tight, vibration-resistant fit that prevents loosening under dynamic loads. The Torx Plus drive system (T25/IP25) allows for higher torque application with minimal slippage, reducing the risk of head stripping and improving assembly line efficiency. With UNF fine threading and a fully threaded body, it ensures maximum thread engagement and holding strength in soft metals, making it an ideal choice for precision engineering applications in electronics, automotive, and machinery manufacturing.

Specification Summary & Compliance

This screw adheres to UNF (Unified National Fine) thread standards with a 10-32 thread size and Class 2A tolerance for precise fit. The length is specified as 1/2" with a tolerance of -0.03" to 0". It is manufactured as a thread-forming tapping screw with a Tri-Lobe shank cross-section and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
