S-93878A132 10-32 x 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
• Excellent thread-forming capability creates permanent, vibration-resistant threads in steel, aluminum, brass and cast iron without chips
• Fine UNF thread spacing provides enhanced holding power and superior resistance to loosening under dynamic loads
• Blunt tip design ensures precise alignment and prevents material splitting during installation in sheet metal applications
• Slotted pan head offers reliable driving compatibility with standard tools while the rounded profile minimizes snagging hazards
• Fully threaded 3/4" length delivers maximum engagement and consistent clamping force throughout the fastened joint
• Optimized installation with specified #15 drill bit (0.18") ensures proper fit and prevents thread stripping

Professional Applications & Engineering Value

These 10-32 UNF thread forming screws deliver exceptional engineering value by solving critical fastening challenges in metal fabrication and assembly. The zinc-plated steel construction provides reliable corrosion protection while maintaining high tensile strength. As thread forming tapping screws, they create strong, permanent threads in ductile materials like steel, aluminum, brass, and cast iron without generating chips that could contaminate sensitive assemblies. The fine thread spacing and fully threaded design ensure maximum resistance to vibration loosening, making them ideal for sheet metal applications, machinery assembly, and industrial equipment where reliable, long-term fastening is essential. The slotted pan head configuration allows for quick installation with standard tools while maintaining a low-profile appearance.

Specification Summary & Compliance

These tapping screws feature precision 10-32 UNF threads with Class 2A tolerance for consistent fit and performance. The thread forming design follows industry standards for self-tapping fasteners, manufactured from high-strength steel with zinc plating for corrosion protection. The 3/4" length and No. 10 screw size provide optimal dimensional accuracy, while the installation requires a #15 drill bit (0.18" diameter) for proper hole preparation. These industrial fasteners comply with relevant mechanical standards and are suitable for various manufacturing and construction applications requiring reliable metal-to-metal fastening solutions.
