• Wide material compatibility for use in brass, cast iron, and sheet metal, offering versatile application across various industrial projects.
• Optimized thread engagement with UNC 1/4"-20 coarse threads and full threading, ensuring strong holding power and vibration resistance.
• Streamlined procurement and compliance by meeting RoHS 3 and REACH environmental regulations, ensuring global supply chain acceptance.
• Precise installation guidance with a recommended No. 7 drill bit (0.201" diameter), facilitating accurate hole preparation and reducing assembly errors.

Professional Applications & Engineering Value

These 1/4"-20 tapping screws are engineered to solve common fastening challenges in sheet metal, cast iron, and brass assemblies. The 410 stainless steel material provides excellent strength and rust resistance, crucial for outdoor or high-moisture environments. The Type F thread cutting feature allows the screw to form its own threads, reducing labor costs and assembly time by eliminating the need for separate tapping operations. With a UNC coarse thread and Phillips drive, these screws deliver high clamp load and are easy to install with standard tools, making them ideal for industrial fasteners in machinery, automotive, and construction applications where durability and reliability are paramount.

Specification Summary & Compliance

This product features a 1/4"-20 UNC coarse thread with a right-hand direction and full threading for consistent performance. The dimensional accuracy adheres to standard industrial tolerances for reliable fit. It is manufactured as a Type F tapping screw with a pan head style and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global distribution and use.
