S-94077A225 1/2"-13 x 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Ultra-corrosion-resistant coated steel construction ensures long-term reliability in harsh industrial environments, reducing maintenance costs and replacement frequency.
• External hex drive design provides superior torque transfer during installation, minimizing tool slippage and ensuring secure fastening in high-torque applications.
• Flanged head design enhances load distribution and prevents pull-through in sheet metal and steel assemblies, improving joint integrity.
• Thread forming (Type C) tapping method creates strong, precise threads without chip removal, ideal for steel and sheet metal where thread durability is critical.
• Coarse UNC 1/2"-13 threading with five-lobe shank delivers excellent holding power and vibration resistance in demanding construction and metalworking applications.
• Fully threaded length of 2 1/2" allows for deep penetration and uniform stress distribution across the entire fastener engagement area.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and material transparency for global industrial supply chains.

Professional Applications & Engineering Value

Engineered for steel and sheet metal applications, these 1/2"-13 UNC hex head tapping screws solve critical fastening challenges in industrial settings. The thread forming design eliminates chip accumulation issues common in metalworking, while the ultra-corrosion-resistant coating prevents degradation in exposed or humid environments. The external hex drive ensures reliable installation with standard tools, reducing assembly time and improving workflow efficiency in construction, machinery, and structural steel projects. With a flanged head that distributes clamping force evenly, these screws prevent material deformation and maintain joint stability under dynamic loads, making them ideal for heavy-duty industrial fasteners where vibration resistance and long-term performance are paramount.

Specification Summary & Compliance

This thread forming screw features UNC coarse threading with standard Class 2A tolerances for consistent fit. Manufactured from coated steel with a five-lobe shank cross-section, it requires a 15/32" (0.4687") drill bit for proper installation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
