S-94077A305 5/8"-11 x 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Ultra-corrosion-resistant coated steel construction ensures long-term reliability in harsh industrial environments
• External hex drive design provides superior torque transmission and prevents tool slippage during installation
• Thread forming tapping method creates strong, permanent threads in steel and sheet metal without chip removal
• Flanged head design eliminates the need for separate washers and distributes clamping force evenly
• Five-lobe shank cross-section enhances resistance to vibration loosening in high-stress applications
• Coarse UNC thread pattern enables faster installation and superior holding power in various materials
• Fully threaded blunt tip allows for precise alignment and consistent engagement throughout the material thickness

Professional Applications & Engineering Value

Engineered specifically for steel and sheet metal applications, these 5/8"-11 UNC hex head tapping screws solve critical assembly challenges in industrial settings. The thread forming design eliminates the risk of metal shavings contaminating sensitive equipment while creating stronger thread engagement than conventional cutting screws. The ultra-corrosion-resistant coating provides essential protection against environmental factors in outdoor or high-moisture installations. With their external hex drive and flanged head, these fasteners deliver exceptional clamping force distribution and simplify installation in confined spaces, making them ideal for structural frameworks, machinery enclosures, and heavy-duty equipment assembly where vibration resistance and long-term performance are paramount.

Specification Summary & Compliance

This 5/8"-11 UNC coarse thread tapping screw features precise Class 2A thread tolerances and fully threaded construction with a blunt tip design. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental responsibility and workplace safety. Manufactured with a 1 1/2" length and 1.04" flange diameter, it's designed for use with 19/32" drill bits (0.5637" diameter) in steel and sheet metal applications requiring heavy-duty fastening solutions.
