S-90054A307 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Excellent holding power in sheet metal due to thread forming technology that creates strong, secure threads without pre-tapping.
• Versatile and secure fastening with an external hex/slotted drive, accommodating various tools for reliable installation.
• Maximum grip and stability from the fully threaded design and integrated flange, distributing load effectively.
• Optimized for 0.025" maximum drilling thickness in sheet metal, ensuring precise and efficient application performance.
• Broad compatibility with a No. 12 screw size and A/AB tapping screw type, meeting common industrial standards.
• Compliance with environmental regulations including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are engineered for robust sheet metal applications, where vibration resistance and long-term durability are critical. The thread forming design eliminates the need for pre-tapped holes, reducing assembly time and minimizing the risk of thread stripping in thin materials. Made from zinc-plated steel, they offer enhanced protection against rust and corrosion, ideal for HVAC, automotive, and machinery enclosures. The external hex/slotted drive provides flexibility for high-torque installation with standard tools, while the flanged head improves clamping force and prevents pull-through. This combination ensures reliable performance in high-stress environments, reducing maintenance and replacement costs.
