S-93880A245 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Enhanced vibration resistance through thread forming technology that creates stronger, more permanent threads in sheet metal
• Maximum installation efficiency with dual external hex/slotted drive options accommodating various tool types
• Increased load distribution from the integrated flange design that prevents pull-through and reduces surface damage
• Optimal material engagement with full threading along the entire 3/4" length for superior holding power
• Simplified installation process using standard No. 21 drill bit (0.159") for precise hole preparation
• Environmental compliance assurance meeting RoHS 3 standards for safe, regulated industrial use

Professional Applications & Engineering Value

These No. 10-16 thread forming tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The zinc-plated steel construction provides reliable corrosion protection, while the thread forming technology displaces material rather than removing it, creating zero-clearance threads that significantly reduce loosening under dynamic loads. The flanged hex head design combines the high torque capability of an external hex with the increased bearing surface of a washer, eliminating the need for separate components. This fully threaded blunt tip screw ensures maximum thread engagement throughout the fastened materials, making it ideal for HVAC systems, electrical enclosures, and industrial machinery where sheet metal fastening demands both strength and durability.

Specification Summary & Compliance

This No. 10-16 x 3/4" tapping screw features precision right-hand threads with approximately 16 threads per inch and Class 2A thread tolerances for consistent performance. Manufactured from zinc-plated steel with a blunt tip and fully threaded shank, it's specifically engineered for thread forming applications in sheet metal using No. 21 drill bit preparation. The product is fully RoHS 3 (2015/863/EU) compliant, meeting international environmental standards for industrial components while delivering reliable fastening performance in demanding sheet metal assembly operations.
