S-93880A313 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced load distribution through integrated flange design that eliminates the need for separate washers
• Optimal thread engagement with full threading along the entire 3/4" length for maximum holding power in sheet metal
• Efficient installation using standard 3/8" external hex drive for quick assembly with common tools
• Reliable thread forming action with Type B tapping design that creates strong, permanent threads without chip removal
• Precision compatibility with 5.5mm (0.2165") drill bits for accurate hole preparation and secure fastening
• Environmental compliance meeting RoHS 3 standards for safe use in regulated applications

Professional Applications & Engineering Value

These 1/4"-14 zinc-plated steel flanged hex tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming design creates precise mating threads in ductile materials without generating chips, eliminating contamination risks in electrical enclosures, HVAC systems, and machinery panels. The combination of fully threaded construction and flanged head provides superior clamp load distribution, preventing material distortion in thin-gauge metals. The blunt tip ensures accurate starting position while the external hex drive allows for high-torque installation with standard industrial tools, making these Type B tapping screws ideal for production line efficiency and maintenance applications requiring reliable, long-term fastening solutions.

Specification Summary & Compliance

These inch-system fasteners feature precise 1/4" diameter threads with 14 TPI right-hand threading and Class 2A thread tolerances for consistent performance. The thread forming tapping method follows industry-standard Type B specifications for sheet metal applications. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety standards are met. The 3/4" length and 0.52" flange diameter provide standardized dimensions for reliable interchangeability in industrial fastening systems.
