S-94209A045 2-56 x 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP7 drive, reducing cam-out and tool wear for reliable fastening in high-volume assembly.
• Excellent thread-forming capability in softer materials like aluminum, brass, and copper, thanks to the Tri-Lobe shank design that displaces material without creating chips.
• Enhanced corrosion resistance from zinc-plated steel construction, ensuring longevity in various industrial environments.
• Optimized for coarse thread applications with UNC 2-56 fully threaded design, providing rapid installation and strong holding power.
• Secure and flush seating with standard pan head profile, distributing clamp load evenly and improving finished appearance.
• Precision length control with 5/8" size and tight tolerance, ensuring consistent engagement and reducing assembly errors.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and export markets.

Professional Applications & Engineering Value

These 2-56 UNC Tri-Lobe tapping screws are engineered to solve common fastening challenges in non-ferrous metals like aluminum, brass, and copper. The thread-forming Tri-Lobe shank design eliminates tapping operations by cold-forming mating threads, which increases pull-out strength and prevents loosening from vibration. Made from zinc-plated steel, they offer a durable, corrosion-resistant finish ideal for electronics enclosures, HVAC components, and automotive assemblies. The Torx Plus IP7 drive ensures maximum torque transfer without slippage, reducing operator fatigue and improving production line efficiency. Fully threaded and paired with a No. 48 drill bit, these screws provide reliable performance in coarse-spacing applications where speed and strength are critical.
