S-90122A334 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with ultra-corrosion-resistant coated alloy steel, extending service life in harsh industrial environments.
• Efficient self-drilling capability with No. 3 drill tip, eliminating the need for pre-drilling and saving installation time in aluminum and sheet metal.
• High drilling capacity of up to 0.21" thickness, providing reliable penetration in various metal applications.
• Secure and stable fastening thanks to the flanged design and external hex drive, ensuring strong holding power and reduced risk of loosening.
• Durable thread forming (BSD type) creates strong, permanent threads in materials, enhancing joint integrity under vibration and load.
• Full threading along the 2" length offers consistent grip and uniform stress distribution for improved fastening performance.
• Wide compatibility with right-hand thread and standard 1/4"-14 size, facilitating easy integration into existing industrial assemblies.

Professional Applications & Engineering Value

This flanged hex head tapping screw is specifically engineered to address common challenges in metalworking, such as time-consuming pre-drilling and corrosion-induced failures. Constructed from ultra-corrosion-resistant coated alloy steel, it withstands exposure to moisture and chemicals, reducing maintenance needs in industrial settings. The self-drilling No. 3 tip allows for quick installation in aluminum and sheet metal, penetrating up to 0.21" without pilot holes, which minimizes labor and tool costs. The external hex drive and flange provide enhanced torque transmission and seating, preventing pull-out in high-stress applications like HVAC systems, automotive assemblies, and construction frameworks. By combining thread forming technology with a fully threaded design, it ensures reliable, vibration-resistant connections that maintain integrity over time, making it an ideal choice for demanding B2B procurement in metal fabrication and repair projects.
